Summary

unknown collector `{0}`

Help

verify the collector name is registered in the agent config

Details

When this fires

Runtime, raised when something asks the engine to act on a collector that was never spawned. The engine looks up the name in its handles map (see Engine::handle in crates/nanook-engine/src/engine/mod.rs) for pause, resume, and trigger calls, and returns this if the name is missing. You will see it through nanook ctl or the admin socket, not via nanook check.

What to check

Check /state or nanook ctl ls for the live list. If you just edited config, make sure the agent reloaded (it spawns on startup or after respawn).
