Instance Method Details
#associate_kms_key(params = {}) ⇒ Struct
Associates the specified KMS key with either one log group in the account, or with all stored CloudWatch Logs query insights results in the account.
When you use AssociateKmsKey
, you specify either the logGroupName
parameter or the resourceIdentifier
parameter. You can't specify
both of those parameters in the same operation.
Specify the
logGroupName
parameter to cause all log events stored in the log group to be encrypted with that key. Only the log events ingested after the key is associated are encrypted with that key.Associating a KMS key with a log group overrides any existing associations between the log group and a KMS key. After a KMS key is associated with a log group, all newly ingested data for the log group is encrypted using the KMS key. This association is stored as long as the data encrypted with the KMS key is still within CloudWatch Logs. This enables CloudWatch Logs to decrypt this data whenever it is requested.
Associating a key with a log group does not cause the results of queries of that log group to be encrypted with that key. To have query results encrypted with a KMS key, you must use an
AssociateKmsKey
operation with theresourceIdentifier
parameter that specifies aquery-result
resource.Specify the
resourceIdentifier
parameter with aquery-result
resource, to use that key to encrypt the stored results of all future StartQuery operations in the account. The response from a GetQueryResults operation will still return the query results in plain text.Even if you have not associated a key with your query results, the query results are encrypted when stored, using the default CloudWatch Logs method.
If you run a query from a monitoring account that queries logs in a source account, the query results key from the monitoring account, if any, is used.
If you delete the key that is used to encrypt log events or log group query results, then all the associated stored log events or query results that were encrypted with that key will be unencryptable and unusable.
It can take up to 5 minutes for this operation to take effect.
If you attempt to associate a KMS key with a log group but the KMS key
does not exist or the KMS key is disabled, you receive an
InvalidParameterException
error.

#cancel_export_task(params = {}) ⇒ Struct
Cancels the specified export task.
The task must be in the PENDING
or RUNNING
state.

#create_delivery(params = {}) ⇒ Types::CreateDeliveryResponse
Creates a delivery. A delivery is a connection between a logical delivery source and a logical delivery destination that you have already created.
Only some Amazon Web Services services support being configured as a delivery source using this operation. These services are listed as Supported [V2 Permissions] in the table at Enabling logging from Amazon Web Services services.
A delivery destination can represent a log group in CloudWatch Logs, an Amazon S3 bucket, or a delivery stream in Firehose.
To configure logs delivery between a supported Amazon Web Services service and a destination, you must do the following:
Create a delivery source, which is a logical object that represents the resource that is actually sending the logs. For more information, see PutDeliverySource.
Create a delivery destination, which is a logical object that represents the actual delivery destination. For more information, see PutDeliveryDestination.
If you are delivering logs cross-account, you must use PutDeliveryDestinationPolicy in the destination account to assign an IAM policy to the destination. This policy allows delivery to that destination.
Use
CreateDelivery
to create a delivery by pairing exactly one delivery source and one delivery destination.
You can configure a single delivery source to send logs to multiple destinations by creating multiple deliveries. You can also create multiple deliveries to configure multiple delivery sources to send logs to the same delivery destination.
You can't update an existing delivery. You can only create and delete deliveries.

# File 'gems/aws-sdk-cloudwatchlogs/lib/aws-sdk-cloudwatchlogs/client.rb', line 652 def create_delivery(params = {}, = {}) req = build_request(:create_delivery, params) req.send_request() end |
#create_export_task(params = {}) ⇒ Types::CreateExportTaskResponse
Creates an export task so that you can efficiently export data from a
log group to an Amazon S3 bucket. When you perform a
CreateExportTask
operation, you must use credentials that have
permission to write to the S3 bucket that you specify as the
destination.
Exporting log data to S3 buckets that are encrypted by KMS is supported. Exporting log data to Amazon S3 buckets that have S3 Object Lock enabled with a retention period is also supported.
Exporting to S3 buckets that are encrypted with AES-256 is supported.
This is an asynchronous call. If all the required information is
provided, this operation initiates an export task and responds with
the ID of the task. After the task has started, you can use
DescribeExportTasks to get the status of the export task. Each
account can only have one active (RUNNING
or PENDING
) export task
at a time. To cancel an export task, use CancelExportTask.
You can export logs from multiple log groups or multiple time ranges to the same S3 bucket. To separate log data for each export task, specify a prefix to be used as the Amazon S3 key prefix for all exported objects.

#create_log_anomaly_detector(params = {}) ⇒ Types::CreateLogAnomalyDetectorResponse
Creates an anomaly detector that regularly scans one or more log groups and look for patterns and anomalies in the logs.
An anomaly detector can help surface issues by automatically discovering anomalies in your log event traffic. An anomaly detector uses machine learning algorithms to scan log events and find patterns. A pattern is a shared text structure that recurs among your log fields. Patterns provide a useful tool for analyzing large sets of logs because a large number of log events can often be compressed into a few patterns.
The anomaly detector uses pattern recognition to find anomalies
,
which are unusual log events. It uses the evaluationFrequency
to
compare current log events and patterns with trained baselines.
Fields within a pattern are called tokens. Fields that vary within a
pattern, such as a request ID or timestamp, are referred to as
dynamic tokens and represented by <*>
.
The following is an example of a pattern:
[INFO] Request time: <*> ms
This pattern represents log events like [INFO] Request time: 327 ms
and other similar log events that differ only by the number, in this
csse 327. When the pattern is displayed, the different numbers are
replaced by <*>

#create_log_group(params = {}) ⇒ Struct
Creates a log group with the specified name. You can create up to 1,000,000 log groups per Region per account.
You must use the following guidelines when naming a log group:
Log group names must be unique within a Region for an Amazon Web Services account.
Log group names can be between 1 and 512 characters long.
Log group names consist of the following characters: a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), '.' (period), and '#' (number sign)
Log group names can't start with the string
aws/
When you create a log group, by default the log events in the log group do not expire. To set a retention policy so that events expire and are deleted after a specified time, use PutRetentionPolicy.
If you associate an KMS key with the log group, ingested data is encrypted using the KMS key. This association is stored as long as the data encrypted with the KMS key is still within CloudWatch Logs. This enables CloudWatch Logs to decrypt this data whenever it is requested.
If you attempt to associate a KMS key with the log group but the KMS
key does not exist or the KMS key is disabled, you receive an
InvalidParameterException
error.
CloudWatch Logs supports only symmetric KMS keys. Do not associate an asymmetric KMS key with your log group. For more information, see Using Symmetric and Asymmetric Keys.

#create_log_stream(params = {}) ⇒ Struct
Creates a log stream for the specified log group. A log stream is a sequence of log events that originate from a single source, such as an application instance or a resource that is being monitored.
There is no limit on the number of log streams that you can create for
a log group. There is a limit of 50 TPS on CreateLogStream
operations, after which transactions are throttled.
You must use the following guidelines when naming a log stream:
Log stream names must be unique within the log group.
Log stream names can be between 1 and 512 characters long.
Don't use ':' (colon) or '*' (asterisk) characters.

#delete_account_policy(params = {}) ⇒ Struct
Deletes a CloudWatch Logs account policy. This stops the policy from applying to all log groups or a subset of log groups in the account. Log-group level policies will still be in effect.
To use this operation, you must be signed on with the correct permissions depending on the type of policy that you are deleting.
To delete a data protection policy, you must have the
logs:DeleteDataProtectionPolicy
andlogs:DeleteAccountPolicy
permissions.To delete a subscription filter policy, you must have the
logs:DeleteSubscriptionFilter
andlogs:DeleteAccountPolicy
permissions.

#disassociate_kms_key(params = {}) ⇒ Struct
Disassociates the specified KMS key from the specified log group or from all CloudWatch Logs Insights query results in the account.
When you use DisassociateKmsKey
, you specify either the
logGroupName
parameter or the resourceIdentifier
parameter. You
can't specify both of those parameters in the same operation.
Specify the
logGroupName
parameter to stop using the KMS key to encrypt future log events ingested and stored in the log group. Instead, they will be encrypted with the default CloudWatch Logs method. The log events that were ingested while the key was associated with the log group are still encrypted with that key. Therefore, CloudWatch Logs will need permissions for the key whenever that data is accessed.Specify the
resourceIdentifier
parameter with thequery-result
resource to stop using the KMS key to encrypt the results of all future StartQuery operations in the account. They will instead be encrypted with the default CloudWatch Logs method.

permission to perform this
operation.
You can specify the log group to search by using either
logGroupIdentifier
or logGroupName
. You must include one of these
two parameters, but you can't include both.
By default, this operation returns as many log events as can fit in 1 MB (up to 10,000 log events) or all the events found within the specified time range. If the results include a token, that means there are more log events available. You can get additional results by specifying the token in a subsequent call. This operation can return empty results while there are more log events available through the token.
The returned log events are sorted by event timestamp, the timestamp
when the event was ingested by CloudWatch Logs, and the ID of the
PutLogEvents
request.
If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account and view data from the linked source accounts. For more information, see CloudWatch cross-account observability.

#put_account_policy(params = {}) ⇒ Types::PutAccountPolicyResponse
Creates an account-level data protection policy or subscription filter policy that applies to all log groups or a subset of log groups in the account.
Data protection policy
A data protection policy can help safeguard sensitive data that's ingested by your log groups by auditing and masking the sensitive log data. Each account can have only one account-level data protection policy.
Sensitive data is detected and masked when it is ingested into a log group. When you set a data protection policy, log events ingested into the log groups before that time are not masked.
If you use PutAccountPolicy
to create a data protection policy for
your whole account, it applies to both existing log groups and all log
groups that are created later in this account. The account-level
policy is applied to existing log groups with eventual consistency. It
might take up to 5 minutes before sensitive data in existing log
groups begins to be masked.
By default, when a user views a log event that includes masked data,
the sensitive data is replaced by asterisks. A user who has the
logs:Unmask
permission can use a GetLogEvents or
FilterLogEvents operation with the unmask
parameter set to
true
to view the unmasked log events. Users with the logs:Unmask
can also view unmasked data in the CloudWatch Logs console by running
a CloudWatch Logs Insights query with the unmask
query command.
For more information, including a list of types of data that can be audited and masked, see Protect sensitive log data with masking.
To use the PutAccountPolicy
operation for a data protection policy,
you must be signed on with the logs:PutDataProtectionPolicy
and
logs:PutAccountPolicy
permissions.
The PutAccountPolicy
operation applies to all log groups in the
account. You can use PutDataProtectionPolicy to create a data
protection policy that applies to just one log group. If a log group
has its own data protection policy and the account also has an
account-level data protection policy, then the two policies are
cumulative. Any sensitive term specified in either policy is masked.
Subscription filter policy
A subscription filter policy sets up a real-time feed of log events from CloudWatch Logs to other Amazon Web Services services. Account-level subscription filter policies apply to both existing log groups and log groups that are created later in this account. Supported destinations are Kinesis Data Streams, Firehose, and Lambda. When log events are sent to the receiving service, they are Base64 encoded and compressed with the GZIP format.
The following destinations are supported for subscription filters:
An Kinesis Data Streams data stream in the same account as the subscription policy, for same-account delivery.
An Firehose data stream in the same account as the subscription policy, for same-account delivery.
A Lambda function in the same account as the subscription policy, for same-account delivery.
A logical destination in a different account created with PutDestination, for cross-account delivery. Kinesis Data Streams and Firehose are supported as logical destinations.
Each account can have one account-level subscription filter policy. If
you are updating an existing filter, you must specify the correct name
in PolicyName
. To perform a PutAccountPolicy
subscription filter
operation for any destination except a Lambda function, you must also
have the iam:PassRole
permission.

#put_data_protection_policy(params = {}) ⇒ Types::PutDataProtectionPolicyResponse
Creates a data protection policy for the specified log group. A data protection policy can help safeguard sensitive data that's ingested by the log group by auditing and masking the sensitive log data.
Sensitive data is detected and masked when it is ingested into the log group. When you set a data protection policy, log events ingested into the log group before that time are not masked.
By default, when a user views a log event that includes masked data,
the sensitive data is replaced by asterisks. A user who has the
logs:Unmask
permission can use a GetLogEvents or
FilterLogEvents operation with the unmask
parameter set to
true
to view the unmasked log events. Users with the logs:Unmask
can also view unmasked data in the CloudWatch Logs console by running
a CloudWatch Logs Insights query with the unmask
query command.
For more information, including a list of types of data that can be audited and masked, see Protect sensitive log data with masking.
The PutDataProtectionPolicy
operation applies to only the specified
log group. You can also use PutAccountPolicy to create an
account-level data protection policy that applies to all log groups in
the account, including both existing log groups and log groups that
are created level. If a log group has its own data protection policy
and the account also has an account-level data protection policy, then
the two policies are cumulative. Any sensitive term specified in
either policy is masked.

#put_delivery_destination(params = {}) ⇒ Types::PutDeliveryDestinationResponse
Creates or updates a logical delivery destination. A delivery destination is an Amazon Web Services resource that represents an Amazon Web Services service that logs can be sent to. CloudWatch Logs, Amazon S3, and Firehose are supported as logs delivery destinations.
To configure logs delivery between a supported Amazon Web Services service and a destination, you must do the following:
Create a delivery source, which is a logical object that represents the resource that is actually sending the logs. For more information, see PutDeliverySource.
Use
PutDeliveryDestination
to create a delivery destination, which is a logical object that represents the actual delivery destination.If you are delivering logs cross-account, you must use PutDeliveryDestinationPolicy in the destination account to assign an IAM policy to the destination. This policy allows delivery to that destination.
Use
CreateDelivery
to create a delivery by pairing exactly one delivery source and one delivery destination. For more information, see CreateDelivery.
You can configure a single delivery source to send logs to multiple destinations by creating multiple deliveries. You can also create multiple deliveries to configure multiple delivery sources to send logs to the same delivery destination.
Only some Amazon Web Services services support being configured as a delivery source. These services are listed as Supported [V2 Permissions] in the table at Enabling logging from Amazon Web Services services.
If you use this operation to update an existing delivery destination, all the current delivery destination parameters are overwritten with the new parameter values that you specify.

#put_delivery_destination_policy(params = {}) ⇒ Types::PutDeliveryDestinationPolicyResponse
Creates and assigns an IAM policy that grants permissions to CloudWatch Logs to deliver logs cross-account to a specified destination in this account. To configure the delivery of logs from an Amazon Web Services service in another account to a logs delivery destination in the current account, you must do the following:
Create a delivery source, which is a logical object that represents the resource that is actually sending the logs. For more information, see PutDeliverySource.
Create a delivery destination, which is a logical object that represents the actual delivery destination. For more information, see PutDeliveryDestination.
Use this operation in the destination account to assign an IAM policy to the destination. This policy allows delivery to that destination.
Create a delivery by pairing exactly one delivery source and one delivery destination. For more information, see CreateDelivery.
Only some Amazon Web Services services support being configured as a delivery source. These services are listed as Supported [V2 Permissions] in the table at Enabling logging from Amazon Web Services services.
The contents of the policy must include two statements. One statement enables general logs delivery, and the other allows delivery to the chosen destination. See the examples for the needed policies.

#put_delivery_source(params = {}) ⇒ Types::PutDeliverySourceResponse
Creates or updates a logical delivery source. A delivery source represents an Amazon Web Services resource that sends logs to an logs delivery destination. The destination can be CloudWatch Logs, Amazon S3, or Firehose.
To configure logs delivery between a delivery destination and an Amazon Web Services service that is supported as a delivery source, you must do the following:
Use
PutDeliverySource
to create a delivery source, which is a logical object that represents the resource that is actually sending the logs.Use
PutDeliveryDestination
to create a delivery destination, which is a logical object that represents the actual delivery destination.

#put_destination(params = {}) ⇒ Types::PutDestinationResponse
Creates or updates a destination. This operation is used only to create destinations for cross-account subscriptions.
A destination encapsulates a physical resource (such as an Amazon Kinesis stream). With a destination, you can subscribe to a real-time stream of log events for a different account, ingested using PutLogEvents.
Through an access policy, a destination controls what is written to
it. By default, PutDestination
does not set any access policy with
the destination, which means a cross-account user cannot call
PutSubscriptionFilter against this destination. To enable this,
the destination owner must call PutDestinationPolicy after
PutDestination
.
To perform a PutDestination
operation, you must also have the

#put_log_events(params = {}) ⇒ Types::PutLogEventsResponse
Uploads a batch of log events to the specified log stream.
The sequence token is now ignored in PutLogEvents
actions.
PutLogEvents
actions are always accepted and never return
InvalidSequenceTokenException
or DataAlreadyAcceptedException
even
if the sequence token is not valid. You can use parallel
PutLogEvents
actions on the same log stream.
The batch of events must satisfy the following constraints:
The maximum batch size is 1,048,576 bytes. This size is calculated as the sum of all event messages in UTF-8, plus 26 bytes for each log event.
None of the log events in the batch can be more than 2 hours in the future.
None of the log events in the batch can be more than 14 days in the past. Also, none of the log events can be from earlier than the retention period of the log group.
The log events in the batch must be in chronological order by their timestamp. The timestamp is the time that the event occurred, expressed as the number of milliseconds after
Jan 1, 1970 00:00:00 UTC
. (In Amazon Web Services Tools for PowerShell and the Amazon Web Services SDK for .NET, the timestamp is specified in .NET format:yyyy-mm-ddThh:mm:ss
. For example,2017-09-15T13:45:30
.)A batch of log events in a single request cannot span more than 24 hours. Otherwise, the operation fails.
Each log event can be no larger than 256 KB.
The maximum number of log events in a batch is 10,000.
The quota of five requests per second per log stream has been removed. Instead,
PutLogEvents
actions are throttled based on a per-second per-account quota. You can request an increase to the per-second throttling quota by using the Service Quotas service.
If a call to PutLogEvents
returns "UnrecognizedClientException"
the most likely cause is a non-valid Amazon Web Services access key ID
or secret key.

#put_metric_filter(params = {}) ⇒ Struct
Creates or updates a metric filter and associates it with the specified log group. With metric filters, you can configure rules to extract metric data from log events ingested through PutLogEvents.
The maximum number of metric filters that can be associated with a log group is 100.
When you create a metric filter, you can also optionally assign a unit and dimensions to the metric that is created.
Metrics extracted from log events are charged as custom metrics. To
prevent unexpected high charges, do not specify high-cardinality
fields such as IPAddress
or requestID
as dimensions. Each
different value found for a dimension is treated as a separate metric
and accrues charges as a separate custom metric.
CloudWatch Logs might disable a metric filter if it generates 1,000 different name/value pairs for your specified dimensions within one hour.
You can also set up a billing alarm to alert you if your charges are higher than expected. For more information, see Creating a Billing Alarm to Monitor Your Estimated Amazon Web Services Charges.

#put_query_definition(params = {}) ⇒ Types::PutQueryDefinitionResponse
Creates or updates a query definition for CloudWatch Logs Insights. For more information, see Analyzing Log Data with CloudWatch Logs Insights.
To update a query definition, specify its queryDefinitionId
in your
request. The values of name
, queryString
, and logGroupNames
are
changed to the values that you specify in your update operation. No
current values are retained from the current query definition. For
example, imagine updating a current query definition that includes log
groups. If you don't specify the logGroupNames
parameter in your
update operation, the query definition changes to contain no log
groups.
You must have the logs:PutQueryDefinition
permission to be able to
perform this operation.

#put_resource_policy(params = {}) ⇒ Types::PutResourcePolicyResponse
Creates or updates a resource policy allowing other Amazon Web Services services to put log events to this account, such as Amazon Route 53. An account can have up to 10 resource policies per Amazon Web Services Region.
4375 4376 4377 4378 |
# File 'gems/aws-sdk-cloudwatchlogs/lib/aws-sdk-cloudwatchlogs/client.rb', line 4375 def put_resource_policy(params = {}, = {}) req = build_request(:put_resource_policy, params) req.send_request() end |
#put_retention_policy(params = {}) ⇒ Struct
Sets the retention of the specified log group. With a retention policy, you can configure the number of days for which to retain log events in the specified log group.
To illustrate, imagine that you change a log group to have a longer retention setting when it contains log events that are past the expiration date, but haven’t been deleted. Those log events will take up to 72 hours to be deleted after the new retention date is reached. To make sure that log data is deleted permanently, keep a log group at its lower retention setting until 72 hours after the previous retention period ends. Alternatively, wait to change the retention setting until you confirm that the earlier log events are deleted.
When log events reach their retention setting they are marked for
deletion. After they are marked for deletion, they do not add to your
archival storage costs anymore, even if they are not actually deleted
until later. These log events marked for deletion are also not
included when you use an API to retrieve the storedBytes
value to
see how many bytes a log group is storing.

#put_subscription_filter(params = {}) ⇒ Struct
Creates or updates a subscription filter and associates it with the specified log group. With subscription filters, you can subscribe to a real-time stream of log events ingested through PutLogEvents and have them delivered to a specific destination. When log events are sent to the receiving service, they are Base64 encoded and compressed with the GZIP format.
The following destinations are supported for subscription filters:
An Amazon Kinesis data stream belonging to the same account as the subscription filter, for same-account delivery.
A logical destination created with PutDestination that belongs to a different account, for cross-account delivery. We currently support Kinesis Data Streams and Firehose as logical destinations.
An Amazon Kinesis Data Firehose delivery stream that belongs to the same account as the subscription filter, for same-account delivery.
An Lambda function that belongs to the same account as the subscription filter, for same-account delivery.
Each log group can have up to two subscription filters associated with
it. If you are updating an existing filter, you must specify the
correct name in filterName
.
To perform a PutSubscriptionFilter
operation for any destination
except a Lambda function, you must also have the iam:PassRole
permission.

#start_live_tail(params = {}) ⇒ Types::StartLiveTailResponse
Starts a Live Tail streaming session for one or more log groups. A Live Tail session returns a stream of log events that have been recently ingested in the log groups. For more information, see Use Live Tail to view logs in near real time.
The response to this operation is a response stream, over which the server sends live log events and the client receives them.
The following objects are sent over the stream:
A single LiveTailSessionStart object is sent at the start of the session.
Every second, a LiveTailSessionUpdate object is sent. Each of these objects contains an array of the actual log events.
If no new log events were ingested in the past second, the
LiveTailSessionUpdate
object will contain an empty array.The array of log events contained in a
LiveTailSessionUpdate
can include as many as 500 log events. If the number of log events matching the request exceeds 500 per second, the log events are sampled down to 500 log events to be included in eachLiveTailSessionUpdate
object.If your client consumes the log events slower than the server produces them, CloudWatch Logs buffers up to 10
LiveTailSessionUpdate
events or 5000 log events, after which it starts dropping the oldest events.A SessionStreamingException object is returned if an unknown error occurs on the server side.
A SessionTimeoutException object is returned when the session times out, after it has been kept open for three hours.
You can end a session before it times out by closing the session stream or by closing the client that is receiving the stream. The session also ends if the established connection between the client and the server breaks.
For examples of using an SDK to start a Live Tail session, see Start a Live Tail session using an Amazon Web Services SDK.

#start_query(params = {}) ⇒ Types::StartQueryResponse
Schedules a query of a log group using CloudWatch Logs Insights. You specify the log group and time range to query and the query string to use.
For more information, see CloudWatch Logs Insights Query Syntax.
After you run a query using StartQuery
, the query results are stored
by CloudWatch Logs. You can use GetQueryResults to retrieve the
results of a query, using the queryId
that StartQuery
returns.
If you have associated a KMS key with the query results in this account, then StartQuery uses that key to encrypt the results when it stores them. If no key is associated with query results, the query results are encrypted with the default CloudWatch Logs encryption method.
Queries time out after 60 minutes of runtime. If your queries are timing out, reduce the time range being searched or partition your query into a number of queries.
If you are using CloudWatch cross-account observability, you can use
this operation in a monitoring account to start a query in a linked
source account. For more information, see CloudWatch cross-account
observability. For a cross-account StartQuery
operation, the
query definition must be defined in the monitoring account.
You can have up to 30 concurrent CloudWatch Logs insights queries, including queries that have been added to dashboards.

#tag_log_group(params = {}) ⇒ Struct
The TagLogGroup operation is on the path to deprecation. We recommend that you use TagResource instead.
Adds or updates the specified tags for the specified log group.
To list the tags for a log group, use ListTagsForResource. To remove tags, use UntagResource.
For more information about tags, see Tag Log Groups in Amazon CloudWatch Logs in the Amazon CloudWatch Logs User Guide.
CloudWatch Logs doesn’t support IAM policies that prevent users from
assigning specified tags to log groups using the
aws:Resource/key-name
or aws:TagKeys
condition keys. For more
information about using tags to control access, see Controlling
access to Amazon Web Services resources using tags.

#tag_resource(params = {}) ⇒ Struct
Assigns one or more tags (key-value pairs) to the specified CloudWatch Logs resource. Currently, the only CloudWatch Logs resources that can be tagged are log groups and destinations.
Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values.
Tags don't have any semantic meaning to Amazon Web Services and are interpreted strictly as strings of characters.
You can use the TagResource
action with a resource that already has
tags. If you specify a new tag key for the alarm, this tag is appended
to the list of tags associated with the alarm. If you specify a tag
key that is already associated with the alarm, the new tag value that
you specify replaces the previous value for that tag.
You can associate as many as 50 tags with a CloudWatch Logs resource.

#untag_log_group(params = {}) ⇒ Struct
The UntagLogGroup operation is on the path to deprecation. We recommend that you use UntagResource instead.
Removes the specified tags from the specified log group.
To list the tags for a log group, use ListTagsForResource. To add tags, use TagResource.
CloudWatch Logs doesn’t support IAM policies that prevent users from
assigning specified tags to log groups using the
aws:Resource/key-name
or aws:TagKeys
condition keys.

#update_anomaly(params = {}) ⇒ Struct
Use this operation to suppress anomaly detection for a specified anomaly or pattern. If you suppress an anomaly, CloudWatch Logs won’t report new occurrences of that anomaly and won't update that anomaly with new data. If you suppress a pattern, CloudWatch Logs won’t report any anomalies related to that pattern.
You must specify either anomalyId
or patternId
, but you can't
specify both parameters in the same operation.
If you have previously used this operation to suppress detection of a
pattern or anomaly, you can use it again to cause CloudWatch Logs to
end the suppression. To do this, use this operation and specify the
anomaly or pattern to stop suppressing, and omit the suppressionType
and suppressionPeriod
parameters.
