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.

Files

River files are plain text files with the .river file extension. You can refer to each River file as a “configuration file” or a “River configuration.”

River files must be UTF-8 encoded and can contain Unicode characters. River files can use Unix-style line endings (LF) and Windows-style line endings (CRLF), but formatters may replace all line endings with Unix-style ones.
