- Availability group collector (replica and database replica states, queues, commit times) and rules: SQLI-AG-001 unhealthy/disconnected replica or suspended data movement (scripts HADR RESUME), SQLI-AG-002 secondary behind (estimated data loss and redo time) - SQL Agent collector using only granted msdb tables (no EXECUTE on msdb functions): SQLI-JOB-001 failed job with the failing step's message (backup/CHECKDB jobs are High), SQLI-JOB-002 SQL Agent not running - Integration tests create a real availability group (CLUSTER_TYPE NONE) and a failing job in the test container (HADR and Agent enabled) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01E3EExwndy8Z22EK2Qpt6BK
