Overview
Deploy configurations to a fleet of collectors and manage them remotely.
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.
You roll a configuration out to the fleet, watch each collector's health and status, detect drift from the version you approved, and roll back, all without logging into individual hosts.
Fleet management delivers configuration to your collectors and reads their status back. It is never in your telemetry data path: telemetry flows directly from your collectors to your backends.
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 connects to Telflo. 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.
Key terms
| Term | Meaning |
|---|---|
| Fleet | A named group of collectors that share one published configuration. |
| Instance | A single collector that has enrolled in a fleet. |
| Install token | A credential in the supervisor bundle that authenticates a collector to its fleet. It can expire and be rotated or revoked. |
| Default version | The published version the fleet assigns to its instances. Set it with Set Default Version. |
| Served configuration | The configuration version Telflo has delivered to an instance. |
| Assigned configuration | The configuration version an instance is set to run. |
| Drift | An instance whose served configuration version does not match its assigned version. |
Prerequisites
- A configuration with a published version. See Versions & publishing.
- Hosts where you can install a collector. Collectors run on Linux (arm64 or amd64/x86_64), in Docker or directly on a host.
