Examples Using State Management › Monitor the Windows Task Scheduler

Monitor the Windows Task Scheduler

This example monitors the Task Scheduler for failed or excessive tasks on Windows. It consists of a set of entries for the sysedge.cf file and an associated schedlgu.cmd script. The schedlgu.cmd script counts *.job files, analyzes the *.txt files in the %SystemRoot%\Tasks directory, and writes the results into the %CASYSEDGE_DATA%\schedlgu.log file. SystemEDGE launches the script and monitors the schedlgu.log file to evaluate the current status.

Copy the schedlgu.cmd script into the %CASYSEDGE%\bin directory or add it to a configuration deployment package that delivers it to the %CASYSEDGE%\bin\managedscripts directory.
