Monitoring Amazon Keyspaces (for Apache Cassandra)

Monitoring is an important part of maintaining the reliability, availability, and performance of Amazon Keyspaces and your other Amazon solutions. Amazon provides the following monitoring tools to watch Amazon Keyspaces, report when something is wrong, and take automatic actions when appropriate:

  • Amazon Keyspaces offers a preconfigured dashboard in the Amazon Web Services Management Console showing the latency and errors aggregated across all tables in the account.

  • Amazon CloudWatch monitors your Amazon resources and the applications you run on Amazon in real time. You can collect and track metrics with customized dashboards. For example, you can create a baseline for normal Amazon Keyspaces performance in your environment by measuring performance at various times and under different load conditions. As you monitor Amazon Keyspaces, store historical monitoring data so that you can compare it with current performance data, identify normal performance patterns and performance anomalies, and devise methods to address issues. To establish a baseline, you should, at a minimum, monitor for system errors. For more information, see the Amazon CloudWatch User Guide.

  • Amazon CloudWatch alarms monitor a single metric over a time period that you specify, and perform one or more actions based on the value of the metric relative to a given threshold over a number of time periods. For example if you use Amazon Keyspaces in provisioned mode with application auto scaling, the action is a notification sent by the Amazon Simple Notification Service (Amazon SNS) to evaluate an Application Auto Scaling policy.

    CloudWatch alarms do not invoke actions simply because they are in a particular state. The state must have changed and been maintained for a specified number of periods. For more information, see Monitoring Amazon Keyspaces with Amazon CloudWatch.

  • Amazon CloudWatch Logs enables you to monitor, store, and access your log files from Amazon Keyspaces tables, CloudTrail, and other sources. CloudWatch Logs can monitor information in the log files and notify you when certain thresholds are met. You can also archive your log data in highly durable storage. For more information, see the Amazon CloudWatch Logs User Guide.

  • Amazon CloudTrail captures API calls and related events made by or on behalf of your Amazon Web Services account and delivers the log files to an Amazon S3 bucket that you specify. You can identify which users and accounts called Amazon, the source IP address from which the calls were made, and when the calls occurred. For more information, see the Amazon CloudTrail User Guide.

Amazon EventBridge is a serverless event bus service that makes it easy to connect your applications with data from a variety of sources. EventBridge delivers a stream of real-time data from your own applications, Software-as-a-Service (SaaS) applications, and Amazon services and routes that data to targets such as Lambda. This enables you to monitor events that happen in services, and build event-driven architectures. For more information, see the Amazon EventBridge User Guide.
