Datadog Agent Agent not collecting GCP metrics

What is Datadog Agent Agent not collecting GCP metrics

Understanding Datadog Agent

Datadog Agent is a powerful tool designed to collect metrics, logs, and traces from your infrastructure and applications. It acts as a bridge between your systems and the Datadog platform, enabling real-time monitoring and analytics. The Agent can be deployed on various environments, including cloud platforms like Google Cloud Platform (GCP), to gather critical performance data.

Identifying the Symptom

One common issue users encounter is the Datadog Agent not collecting GCP metrics. This symptom is typically observed when expected metrics from GCP services do not appear in the Datadog dashboard, leading to gaps in monitoring and analysis.

Common Error Messages

While there may not be an explicit error message, the absence of GCP metrics in your Datadog dashboard is a clear indicator of this issue.

Exploring the Issue

The root cause of the Datadog Agent not collecting GCP metrics often lies in either the metrics collection not being enabled or the Agent lacking the necessary permissions to access GCP resources. Without proper configuration and permissions, the Agent cannot retrieve the required data from GCP services.

Permissions and Configuration

To collect metrics from GCP, the Datadog Agent requires specific permissions to access GCP APIs. Additionally, the metrics collection feature must be explicitly enabled in the Agent's configuration.

Steps to Fix the Issue

To resolve the issue of the Datadog Agent not collecting GCP metrics, follow these steps:

1. Enable GCP Metrics Collection

Open the Datadog GCP Integration page. Ensure that the GCP integration is enabled and configured correctly. Verify that the necessary GCP services are selected for metrics collection.

2. Grant Necessary Permissions

Access the GCP IAM & Admin console. Create or update a service account with the following roles: roles/monitoring.viewer and roles/logging.viewer. Ensure that the service account key is correctly configured in the Datadog Agent.

3. Update Datadog Agent Configuration

Edit the datadog.yaml file located in the Agent's configuration directory. Add or update the gcp_project_id and gcp_credentials_file fields with the appropriate values. Restart the Datadog Agent to apply the changes using the command: sudo service datadog-agent restart.

Conclusion

By ensuring that GCP metrics collection is enabled and the Datadog Agent has the necessary permissions, you can effectively resolve the issue of missing GCP metrics. Regularly review your configuration and permissions to maintain seamless integration between Datadog and GCP.
