PerformanceMonitor 3.12.0 is out. Free.

Darling now tracks backups and CHECKDB for every database, checks SQL Agent alerts, and warns before an identity column runs out.

Sorry if 3.11 broke your route edits. Fixed.

PerformanceMonitor 3.11.0 is out now. Free.

Darling can hand an alert to your own AI agent. Give it the keys and it can force a plan or kill a session, and every move gets logged. Also new: query tags and quiet windows.

PerformanceMonitor 3.9.0 is out.

Alerts open right into the charts that explain them. Query plans get a minimap and flag possible parameter sniffing. PostgreSQL servers get analyzed too: vacuum, bloat, blocking, waits.

PerformanceMonitor 3.8.0: build your own alert rules on any metric it collects, SQL Server or Postgres. High CPU pages name the backup that caused them. Long query alerts name the Agent job. Your 2am self deserves this.
