You certainly could create your own version of the app to do what you want. It would just be a matter of locating the part of the current script that you need and pasting that into your new app and then modifying to do what you want.
I have created some of my own Admin apps but not this one.
I would advise not updating the current Operations Monitor app. Make a duplicate and then modify.
I am not of a way to modify the QMC itself. I doubt that you would want to do that as updates could get tricky.
No reply so....
have you actually configure the monitor apps, so they know where the file store is that ontain the acrchived log file?
