Sometimes it can be difficult to monitor a application. For example even if the application hand the process can still be there. A solution can be to monitor if the application still write anything to the logfile. I have written a simple VB script that will monitor that.<\/font><\/p>\n

strComputer = \".\"
\nSet objFSO = CreateObject(\"Scripting.FileSystemObject\")
\nSet objFile = objFSO.GetFile(\"c:\\log.txt\")
\nConst EVENT_WARNING = 2
\nSet objShell = CreateObject(\"Wscript.Shell\")<\/code>If DateDiff(\"n\", objFile.DateLastModified, Now) > 1 Then
\nobjShell.LogEvent EVENT_WARNING, _
\n\"objFile is older than 4 hours. Please investigate. The file is: \" & objFile
\nend If<\/p>\n

<\/code>If DateDiff(\"n\", objFile.DateLastModified, Now) > 1 Then <\/code>
\nThis line is interesting. “n”\u00c2\u00a0menas minute, in this case an alert will be generated if the file haven’t been updated for a minute.
\nYou can switch “n” to one of the following:<\/p>\n

m – months
\nd – days
\nh – hours
\nn – minutes
\ns – seconds<\/p>\n

If the file isent newer than your settings a event will be generated in the local event viewer. That event we can collect with MOM.<\/p>\n

This line controlls which file to monitor
\nSet objFile = objFSO.GetFile(\"c:\\log.txt\")<\/code><\/p>\n

How-to make MOM send alerts<\/p>\n
