gcp-idle-resources-metrics
Identify unused resources at Google Cloud Platform through Prometheus’ metrics
Current supported services
- Google Compute Engine
- Instances
- Disks
Usage
Set up a service account on the project you want to monitor. You must grant roles/compute.viewer to it.
You can authenticate by setting the Application Default Credentials (i.e: Placing the service account’s JSON key and setting the environment variable GOOGLE_APPLICATION_CREDENTIALS=path-to-credentials.json) or letting the application automatically load the credentials from metadata (Workload Identity is recomended).
You must set, at least, the project ID and the regions you want to monitor. Either by:
- Specifying through command args
--project_id --regions us-east1,us-central1 - Specifying through environment variables
GCP_PROJECT_ID= GCP_REGIONS=us-east1,us-central1(if authenticating through metadata, the project doesn’t need to be specified)
Docker
