Fleet management
Overview
Deploy configurations to collectors and manage them over OpAMP.
Fleet management connects a configuration you built in Telflo to the collectors running in your infrastructure. Instead of copying YAML to each host, your collectors connect to Telflo, pull their configuration, and report their status.
Telflo uses OpAMP (the Open Agent Management Protocol) to manage collectors remotely. OpAMP is the open protocol for sending configuration to telemetry agents and receiving their health and status.
The Fleet management section appears when fleet management is enabled for your account.
How it works
- Publish a configuration version. See Versions & publishing.
- Create a fleet from the published version. The fleet issues an install token and a supervisor bundle. See Create a fleet.
- Install collectors on your hosts from the bundle. Each collector runs a supervisor that speaks OpAMP. See Install collectors.
- Each collector connects to Telflo, pulls its assigned configuration, applies it, and reports the result.
- Track the fleet from its detail page. See Monitor a fleet.
