Monitor
Continuous observation of state over time
Definition
Mechanism
A persistent process that uses a Loop to repeatedly execute Observe on a target System or State at defined intervals. It compares the observed state against a baseline or invariant, emitting a Signal if a deviation (Anomaly) is detected.
Invariants
- Liveness: runs continuously or at `interval`.
- Perturbs what it observes: repeated Observe consumes resources at the target and leaves records there. The degree varies; the fact does not.
Risks
Failure modes
Monitoring load becomes the {{anomaly}}
the observation cost is large enough to shift the baseline it is measuring against.
Baseline drift
the target changes legitimately and the unchanged baseline reports it as deviation.
