Query metrics from other data sources
You can use CloudWatch to query, visualize, and create alarms for metrics from other data sources. To do so, you connect CloudWatch to the other data sources. This gives you a single, consolidated monitoring experience within the CloudWatch console. You can have a unified view of your infrastructure and application metrics regardless of where the data is stored, helping you identify and resolve issues faster.
After you connect to a data source using a CloudWatch wizard, CloudWatch creates an AWS CloudFormation stack that deploys and configures an AWS Lambda function. This Lambda function runs on demand every time you query the data source. The CloudWatch query builder shows you in real time a list of elements that can be queried, such as metrics, tables, fields, or labels. As you make choices, the query builder pre-populates a query in the native language of the selected source.
CloudWatch provides guided wizards for you to connect to the following data sources. For these data sources, you provide basic information to identify the data source and credentials. You can also manually create connectors to other data sources by creating your own Lambda functions.
Amazon OpenSearch Service– Derive metrics from your OpenSearch Service logs and traces.
Amazon Managed Service for Prometheus– Query these metrics using PromQL.
Amazon RDS for MySQL – Use SQL to convert data stored in your Amazon RDS tables into metrics.
Amazon RDS for PostgreSQL– Use SQL to convert data stored in your Amazon RDS tables into metrics.
Amazon S3 CSV files– Display metrics data from a CSV file stored in an Amazon S3 bucket.
Microsoft Azure Monitor– Query metrics from your Microsoft Azure Monitor account.
Prometheus– Query these metrics using PromQL.
After you create connectors to data sources, see Creating a graph of metrics from another data source for information about graphing a metric from a data source. For information about setting an alarm on a metric from a data source, see Create an alarm based on a connected data source.
