  A "cloud-monitoring" source provides a client for the Cloud Monitoring API.

## About

The `cloud-monitoring` source provides a client to interact with the [Google
Cloud Monitoring API](https://cloud.google.com/monitoring/api). This allows
tools to access cloud monitoring metrics explorer and run promql queries.

Authentication can be handled in two ways:

1.  **Application Default Credentials (ADC):** By default, the source uses ADC
    to authenticate with the API.
2.  **Client-side OAuth:** If `useClientOAuth` is set to `true`, the source will
    expect an OAuth 2.0 access token to be provided by the client (e.g., a web
    browser) for each request.
