Telegraf Controller documentation

Telegraf Controller is a centralized application for managing Telegraf deployments at scale. Use it to define configurations once and apply them consistently across fleets of agents. Monitor agent health and roll out updates without manually editing individual agents.

Key features

• Create and manage agent configurations
• Connect agents to Telegraf Controller
• Monitor the overall health of your agent deployment
• Roll out changes safely and verify agent status
• Apply custom logic to agents to identify when they are considered “not reporting”

Configuration and agent workflow

• Create and store Telegraf configurations in Telegraf Controller
• Start a Telegraf agent, pulling its configuration from Telegraf Controller, and have it regularly check for configuration updates.
• Agents use the Telegraf Heartbeat output plugin (available with Telegraf v1.37+) to report their status back to Telegraf Controller
• Telegraf Controller provides agent-specific and deployment-wide health information.
• When you update a configuration, agents see the change and load the updated configuration.
