## How it works

[GCP Cloud Monitoring data source: Query GCP metrics directly from Grafana](cp-olly-gcp-monitoring-ds-light.svg "GCP Cloud Monitoring data source: Query GCP metrics directly from Grafana")

Authenticate with a service account JSON key, or use workload identity when you run Grafana in GKE. The plugin supports PromQL, Monitoring Query Language (MQL), and a visual query builder. For multi-project setups, grant your service account permissions across the projects and query them all from one Grafana instance.

## What you get

- All GCP service metrics
- PromQL, MQL, and visual builder query modes
- Alignment and aggregation
- Template variables
- Label filtering

## Considerations

- API latency
- Per-project authentication, typically
- Alert evaluation calls the API

## Authentication options

Service account JSON key or workload identity
