Caution

Grafana Agent has reached End-of-Life (EOL) on November 1, 2025. Agent is no longer receiving vendor support and will no longer receive security or bug fixes. Current users of Agent Static mode, Agent Flow mode, and Agent Operator should proceed with migrating to Grafana Alloy. If you have already migrated to Alloy, no further action is required. Read more about why we recommend migrating to Grafana Alloy.

Important: This documentation is about an older version. It's relevant only to the release noted, many of the features and functions have been updated or replaced. Please view the current version.
