KPIs for .NET Monitoring, Automation & Session Replay

Windows User Session Replay

X

X

Windows User Login

X

X

Count of Windows user logins.

Windows User Click

X

X

A business-meaningful click matching a configured selector (vs. Mouse Click's unconditional telemetry), measured by response duration.

Windows Mouse Click

X

X

Raw, unconditional telemetry for any mouse click on a UI control.

X

X

Windows Change Event

X

X

Windows Freeze

X

X

Duration a monitored window was unresponsive before recovering (SendMessageTimeout polling); recorded on recovery, not onset.

Windows Crash

X

X

The monitored process exited with a non-zero code (unhandled exception, access violation, WER fast-fail); any non-clean exit qualifies.

ASPNET Request Execution Time

X

Milliseconds to execute the last request (ISAPI level).

ASPNET Request Wait Time

X

Milliseconds the most recent request waited in queue before processing.

ASPNET Worker Process Restarts

X

Number of times a worker process restarted on the server.

IIS Errors

X

Failed requests parsed from IIS error logs.

IIS Failed Request

Percent of elapsed time spent performing garbage collection.

NET GDI Objects

X

Current GDI object count owned by the target process — classic native-leak signal (agent collected).

NET USER Objects

X

Current USER object count (windows, menus, hooks) owned by the target process — classic native-leak signal (agent collected).

NET Thread Contention Rate

X

Rate at which threads unsuccessfully attempt to acquire a managed lock.
