Monitoring Amazon Managed Prometheus (AMP)

Hello, I am looking for the same thing. For now the only useful piece of information I could find is from the Cost Explorer.

We would like to see metrics like prometheus_tsdb_head_series or similar that show how many samples we have in AMP.

This is already possible:

awscurl --service="aps" \
  --region="us-east-1" \
  "https://aps-workspaces.us-east-1.amazonaws.com/workspaces/${WORSKPACE_ID}/api/v1/query?query=prometheus_tsdb_head_series"
