    Description

      PMM Server can support up to 100 AWS RDS instances. When enhanced monitoring is configured, rds_exporter will crash when attempting to add greater than 100 AWS RDS instances.

      RDS exporter calls cloudwatch's method FilterLogEvents with a parameter LogStreamNames,
      which cannot be longer than 100 elements:

      PR: https://github.com/percona/rds_exporter/pull/47

       

      QA: no need to have extensive testing on 100+ RDS. Making sure we don't  have regression is good enough
