Question : Limiting API calls

Antoine-Sevec commented 3 months ago

Hi !

Is it possible to limit API calls to AWS with a variable ?

We have a very large increase in our CloudWatch API (GetMetricData) costs and would like to be able to reduce the frequency.

Thank you for your support

Hello,

The exporter exposes the rds_api_call_total metrics, so you can confirm if the costs are related to the exporter (also visible in the exporter's internal dashboard).

Unfortunately, the exporter doesn't support yet instance filtering, so metrics of all RDS instances will be scrapped.

As mitigation, you may:

Increase the Prometheus Scrape interval, having a 5 minutes metrics polling could reduce API calls
Disable some collectors in configuration, mainly the logs size that need many calls to the AWS RDS API.

I hope it will help
