Questions tagged [amazon-cloudwatch]

Amazon CloudWatch provides monitoring for AWS cloud resources and the applications customers run on AWS. Use this tag when asking about CW features such as metrics or alarms. Use amazon-cloudwatchlogs instead when asking about log groups, log streams, and metric filters.

From the web site:

Developers and system administrators can use it to collect and track metrics, gain insight, and react immediately to keep their applications and businesses running smoothly. Amazon CloudWatch monitors AWS resources such as Amazon EC2 and Amazon RDS DB instances, and can also monitor custom metrics generated by a customer’s applications and services.

Usage Guidance

  • Use this tag when asking about CW metrics or CW alarms, the CW API, etc.
  • Do not use this tag when asking only about log groups, log streams, metric filters, etc; use instead.
  • Use both if asking about both (for example, if asking about a CW Logs metric filter that aggregates in a CW custom metric that triggers a CW alarm)

When does AWS CloudWatch create new log streams?

AWS CloudWatch has Log Groups and Log streams. A log group seems reasonable to me: Each product (e.g. each Lambda function, each Sagemaker endpoint) has its own log group. But then there are log streams. When does AWS CloudWatch create new log…
