Problem

The SRE team is hunting compound failures, the records where several independent alarms trip at once. Surface every error record where at least two of these markers appear: 'Error' in the type name, 'null' in the message, 'api' in the service name, or a severity of 'error' or 'ERROR'.

Summary

The worst failures never arrive alone.
