Infrastructure as Code (IaC) approach for database monitoring using pod annotations.

Coroot can now automatically discover and collect metrics from database instances (pods) annotated with coroot.com/*-scrape annotations.
For example, to enable Postgres-specific metrics collection from a CloudNativePG database, configure the Cluster with the following annotations:

apiVersion: postgresql.cnpg.io/v1
kind: Cluster
metadata:
  name: cnpg-example
spec:
  instances: 2
  inheritedMetadata:
    annotations:
      coroot.com/postgres-scrape: "true"
      coroot.com/postgres-scrape-credentials-secret-name: cnpg-app
      coroot.com/postgres-scrape-credentials-secret-username-key: username
      coroot.com/postgres-scrape-credentials-secret-password-key: password
