使用配置采样、组和加密设置Amazon X-RayAPI

Amazon X-Ray 提供用于配置采样规则、组规则和加密设置的 API。

加密设置

使用PutEncryptionConfig要指定Amazon Key Management Service(Amazon KMS) 用于加密的密钥。

注意

X-Ray 不支持非对称 KMS 密钥.

$ aws xray put-encryption-config --type KMS --key-id alias/aws/xray
{
    "EncryptionConfig": {
        "KeyId": "arn:aws:kms:us-east-2:123456789012:key/c234g4e8-39e9-4gb0-84e2-b0ea215cbba5",
        "Status": "UPDATING",
        "Type": "KMS"
    }
}

对于密钥 ID，您可以使用别名（如示例中所示）、密钥 ID 或 Amazon 资源名称 (ARN)。

使用 GetEncryptionConfig 获取当前配置。当 X-Ray 应用设置时，状态将从UPDATING到ACTIVE.

$ aws xray get-encryption-config
{
    "EncryptionConfig": {
        "KeyId": "arn:aws:kms:us-east-2:123456789012:key/c234g4e8-39e9-4gb0-84e2-b0ea215cbba5",
        "Status": "ACTIVE",
        "Type": "KMS"
    }
}

要停止使用 KMS 密钥并使用默认加密，请将加密类型设置为NONE.

$ aws xray put-encryption-config --type NONE
{
    "EncryptionConfig": {
        "Status": "UPDATING",
        "Type": "NONE"
    }
}

采样规则

您可以管理采样规则在您的账户中使用 X-Ray API。有关添加和管理标签的更多信息，请参阅为 X-Ray 采样规则和组添加标签.

利用 GetSamplingRules 获取所有采样规则。

$ aws xray get-sampling-rules
{
    "SamplingRuleRecords": [
        {
            "SamplingRule": {
                "RuleName": "Default",
                "RuleARN": "arn:aws:xray:us-east-2:123456789012:sampling-rule/Default",
                "ResourceARN": "*",
                "Priority": 10000,
                "FixedRate": 0.05,
                "ReservoirSize": 1,
                "ServiceName": "*",
                "ServiceType": "*",
                "Host": "*",
                "HTTPMethod": "*",
                "URLPath": "*",
                "Version": 1,
                "Attributes": {}
            },
            "CreatedAt": 0.0,
            "ModifiedAt": 1529959993.0
        }
    ]
}

默认规则应用于与其他规则不匹配的所有请求。它是最低优先级的规则，不能删除。但是，您可以使用 UpdateSamplingRule 更改速率和容器大小。

例 的 API 输入UpdateSamplingRule— 10000-默认t.json
{
    "SamplingRuleUpdate": {
        "RuleName": "Default",
        "FixedRate": 0.01,
        "ReservoirSize": 0
    }
}

以下示例使用之前的文件作为输入，将默认规则更改为没有存储库的百分比。标签是可选的。如果选择添加标签，则需要标签密钥，标签值是可选的。要从取样规则中删除现有标签，请使用UntagResource

$ aws xray update-sampling-rule --cli-input-json file://1000-default.json --tags [{"Key": "key_name","Value": "value"},{"Key": "key_name","Value": "value"}]
{
    "SamplingRuleRecords": [
        {
            "SamplingRule": {
                "RuleName": "Default",
                "RuleARN": "arn:aws:xray:us-east-2:123456789012:sampling-rule/Default",
                "ResourceARN": "*",
                "Priority": 10000,
                "FixedRate": 0.01,
                "ReservoirSize": 0,
                "ServiceName": "*",
                "ServiceType": "*",
                "Host": "*",
                "HTTPMethod": "*",
                "URLPath": "*",
                "Version": 1,
                "Attributes": {}
            },
            "CreatedAt": 0.0,
            "ModifiedAt": 1529959993.0
        },

利用 CreateSamplingRule 创建更多采样规则。当您创建规则时，大多数规则字段都是必填字段。以下示例将创建两条规则。这第一条规则为 ScoreKeep 示例应用程序设定了基本费率。它匹配 API 提供的所有与更高优先级规则不匹配的请求。

例 的 API 输入UpdateSamplingRule— 9000-base-scorekeep.json
{
    "SamplingRule": {
        "RuleName": "base-scorekeep",
        "ResourceARN": "*",
        "Priority": 9000,
        "FixedRate": 0.1,
        "ReservoirSize": 5,
        "ServiceName": "Scorekeep",
        "ServiceType": "*",
        "Host": "*",
        "HTTPMethod": "*",
        "URLPath": "*",
        "Version": 1
    }
}

第二条规则也适用于 ScoreKep，但它具有更高的优先级，更具体。该规则为轮询请求设置了非常低的采样率。这些是客户端每隔几秒钟发出的 GET 请求，以检查游戏状态的变化。

例 的 API 输入UpdateSamplingRule— 5000 个轮询分数 keep.json
{
    "SamplingRule": {
        "RuleName": "polling-scorekeep",
        "ResourceARN": "*",
        "Priority": 5000,
        "FixedRate": 0.003,
        "ReservoirSize": 0,
        "ServiceName": "Scorekeep",
        "ServiceType": "*",
        "Host": "*",
        "HTTPMethod": "GET",
        "URLPath": "/api/state/*",
        "Version": 1
    }
}

标签是可选的。如果选择添加标签，则需要标签密钥，标签值是可选的。

$ aws xray create-sampling-rule --cli-input-json file://5000-polling-scorekeep.json --tags [{"Key": "key_name","Value": "value"},{"Key": "key_name","Value": "value"}]
{
    "SamplingRuleRecord": {
        "SamplingRule": {
            "RuleName": "polling-scorekeep",
            "RuleARN": "arn:aws:xray:us-east-1:123456789012:sampling-rule/polling-scorekeep",
            "ResourceARN": "*",
            "Priority": 5000,
            "FixedRate": 0.003,
            "ReservoirSize": 0,
            "ServiceName": "Scorekeep",
            "ServiceType": "*",
            "Host": "*",
            "HTTPMethod": "GET",
            "URLPath": "/api/state/*",
            "Version": 1,
            "Attributes": {}
        },
        "CreatedAt": 1530574399.0,
        "ModifiedAt": 1530574399.0
    }
}
$ aws xray create-sampling-rule --cli-input-json file://9000-base-scorekeep.json
{
    "SamplingRuleRecord": {
        "SamplingRule": {
            "RuleName": "base-scorekeep",
            "RuleARN": "arn:aws:xray:us-east-1:123456789012:sampling-rule/base-scorekeep",
            "ResourceARN": "*",
            "Priority": 9000,
            "FixedRate": 0.1,
            "ReservoirSize": 5,
            "ServiceName": "Scorekeep",
            "ServiceType": "*",
            "Host": "*",
            "HTTPMethod": "*",
            "URLPath": "*",
            "Version": 1,
            "Attributes": {}
        },
        "CreatedAt": 1530574410.0,
        "ModifiedAt": 1530574410.0
    }
}

要删除采样规则，请使用 DeleteSamplingRule。

$ aws xray delete-sampling-rule --rule-name polling-scorekeep
{
    "SamplingRuleRecord": {
        "SamplingRule": {
            "RuleName": "polling-scorekeep",
            "RuleARN": "arn:aws:xray:us-east-1:123456789012:sampling-rule/polling-scorekeep",
            "ResourceARN": "*",
            "Priority": 5000,
            "FixedRate": 0.003,
            "ReservoirSize": 0,
            "ServiceName": "Scorekeep",
            "ServiceType": "*",
            "Host": "*",
            "HTTPMethod": "GET",
            "URLPath": "/api/state/*",
            "Version": 1,
            "Attributes": {}
        },
        "CreatedAt": 1530574399.0,
        "ModifiedAt": 1530574399.0
    }
}

组

您可以使用 X-Ray API 管理您账户中的组。组是由筛选条件表达式定义的跟踪的集合。您可以使用组生成其他服务图并提供 Amazon CloudWatch 指标。请参阅从获取数据Amazon X-Ray以了解有关通过 X-Ray API 使用服务图和指标的更多详细信息。有关组的更多信息，请参阅配置组. 有关添加和管理标签的更多信息，请参阅为 X-Ray 采样规则和组添加标签.

使用 CreateGroup 创建一个组。标签是可选的。如果选择添加标签，则需要标签密钥，标签值是可选的。

$ aws xray create-group --group-name "TestGroup" --filter-expression "service(\"example.com\") {fault}" --tags [{"Key": "key_name","Value": "value"},{"Key": "key_name","Value": "value"}]
{
    "GroupName": "TestGroup",
    "GroupARN": "arn:aws:xray:us-east-2:123456789012:group/TestGroup/UniqueID",
    "FilterExpression": "service(\"example.com\") {fault OR error}"
}

使用获取所有现有群组GetGroups.

$ aws xray get-groups
{
    "Groups": [
        {
            "GroupName": "TestGroup",
            "GroupARN": "arn:aws:xray:us-east-2:123456789012:group/TestGroup/UniqueID",
            "FilterExpression": "service(\"example.com\") {fault OR error}"
        },
		{
            "GroupName": "TestGroup2",
            "GroupARN": "arn:aws:xray:us-east-2:123456789012:group/TestGroup2/UniqueID",
            "FilterExpression": "responsetime > 2"
        }
    ],
	"NextToken": "tokenstring"
}

使用更新组UpdateGroup. 标签是可选的。如果选择添加标签，则需要标签密钥，标签值是可选的。要从组中删除现有标签，请使用UntagResource.

$ aws xray update-group --group-name "TestGroup" --group-arn "arn:aws:xray:us-east-2:123456789012:group/TestGroup/UniqueID" --filter-expression "service(\"example.com\") {fault OR error}" --tags [{"Key": "Stage","Value": "Prod"},{"Key": "Department","Value": "QA"}]
{
    "GroupName": "TestGroup",
    "GroupARN": "arn:aws:xray:us-east-2:123456789012:group/TestGroup/UniqueID",
    "FilterExpression": "service(\"example.com\") {fault OR error}"
}

删除组DeleteGroup.

$ aws xray delete-group --group-name "TestGroup" --group-arn "arn:aws:xray:us-east-2:123456789012:group/TestGroup/UniqueID" 
    {
    }
