SQLMonitor brings availability, waits, workload, blocking and long-running request diagnostics into PRTG — with bounded local logging and a deliberately read-only shadow-analysis workflow.
From broad performance signals. To the query that matters.
Performance
Availability, waits, workload and resource counters for continuous operational visibility.
LONREQ
Bounded diagnostics for long-running requests, with optional local activity detail.
BLOCKED
Detect blocked SQL activity and expose the workload that deserves attention.


Capture useful diagnostics. Keep the scope controlled.
SQLMonitor 1.5.1.0 can write local diagnostic material on the PRTG probe. Keep access restricted, use safe SQL logging when required and set a suitable maximum file size.

Test a termination policy. Change nothing in SQL Server.
Shadow analysis identifies sessions that would meet a selected policy and writes the result to SQLMonitor_LONREQ_SHADOW.log. It is deliberately read-only.

Channels: ShadowRoot_Count, WouldKill_Count, ShadowRoot_MaxSec and ShadowLog_Error.
No active SQL KILL is performed by SQLMonitor 1.5.1.0.
