A user asked for help with an unhealthy monitor on ControlUp. They suspected a logon trigger to be the cause and found a solution by filtering the triggers to only run on sessions with valid parameters. A different user suggested checking the automated actions queue and restarting the affected monitor. Registry keys can also be set to delay the problem, but a permanent fix will be available in 9.1 or partial fix in 9.0.5.
Read the entire ‘Troubleshooting an Unhealthy Monitor on ControlUp’ thread below:
When a monitors Automated Actions Health state is Unhealthy, is there something I can look at to help me troubleshoot? I think I have it isolated to a logon trigger that runs a really light AD query for user-specific information then adds tags to the machine\session, but I can’t tell why. The monitor itself has resources to spare, and I’ve cycled services on a couple of occasions. The only long-term fix so far has been to turn off that trigger…but I want it! lol
The automated actions queue is growing.
Check this. I’m willing to bet the first items in the queue have been there for a while
If that’s the case. You’ll want to restart the affected monitor.
There are some registry keys you can set to delay the problem. But for a permanent fix you’re waiting for 9.1
9.0.5 has a partial fix if you’re not on that yet
That snippet confirmed it was my logon triggers that were clogging things up. In the other thread you mentioned something about blank machine column entries. Machines were fine for me but the user column was empty or not the format I was expecting. Solid chance my script was bombing out or prompting input or something goofy I didn’t expect with malformed params.
I set the script to abort if params were empty, and added a filter on the trigger that requires "DOMAIN*" as user which I’m hoping will only attempt to run the scripts on sessions that actually have the valid params. I’ll keep an eye on it!
