alert: silence non-Mobula head_lag stale alerts - #922
Merged
Conversation
Rename AggregatorHeadLagStale to MobulaHeadLagStale and filter the expression on aggregator='mobula'. Non-Mobula aggregator health (gecko, codex, ...) is tracked via log tailing, not paged. Operator feedback 2026-07-06: 'on veut dans l'alerting seulement si ca concerne mobula; le reste on sen fou'. The rule previously fired every few hours on gecko/bnb because the WBNB/BUSD pool went idle in 2024 (separate fix #920 replaces that pool with WBNB/USDT V3), and periodically on codex due to WS disconnects — both being third-party issues Mobula operators cannot act on. Prometheus alert_type label + severity stay identical so the alertmanager routing / silencer rules keep working.

Rename
AggregatorHeadLagStale→MobulaHeadLagStaleand filter onaggregator="mobula". Non-Mobula aggregators (gecko, codex) are tracked via log tailing only.Rationale
The old rule fired every few hours on gecko/bnb (dead WBNB/BUSD pool — separate fix in #920) and periodically on codex (WS disconnects). Both are third-party issues Mobula operators cannot act on.
