OpenTelemetry Collector exporter experiences retryable errors due to backend unavailability
The OpenTelemetry Collector may intermittently fail to export telemetry data when the backend API is unavailable or overloaded. These failures manifest as timeouts (`context deadline exceeded`) or transient HTTP 502 responses. While retry logic is typically enabled, repeated failures can introduce delay or backpressure.

MongoDB Replica Set Primary Election Failure
Detects high-severity MongoDB replica set primary election failures that result in no primary node being available,causing complete service unavailability. This rule targets catastrophic conditions that break replica set consensus:
  • Primary node failures followed by election timeouts where no secondary can become primary
  • Network partitions isolating replica set members and preventing quorum formation
  • Heartbeat failures and connectivity issues leading to election failures
  • Replica set state transitions indicating election problems
