Error: “Install .NET FW 4.8 on the target machine” Upgrading ControlUp Monitors

Posted on

A user was trying to upgrade ControlUp Monitors from 8.7.0.579 but kept getting a message to install .NET FW 4.8 on the target machine. This is a known issue which is fixed either by patching or uninstalling a patch (specifically ms patch kb5011048). Rolling back the upgrade was the current solution, but the user had the current version 4.8 (not 4.8.1) and a clean install worked. The KB article for this issue is: Error when deploying ControlUp Monitor: Install .NET FW 4.8 on the target machine.

Will Data sources fail over to a different Site if all ControlUp Monitors in that site are down?

Posted on

A user asked about a recent feature where data sources will failover to a different site if all monitors in that site are down. It turns out that this is not a feature, but the team is working on data aggregation between sites instead.

Troubleshooting a Trigger to Delete Profiles in ControlUp

Posted on

A user was trying to set up a trigger that would delete profiles older than one day if disk space drops below 10%, but the trigger wouldn't run. It turned out that it needed to be set up to delete at an exact threshold (e.g., 10%), and not a range (e.g., 9% to 11%). The user enabled an email alert to confirm the CU was picking up the trigger, and adjusted the settings so it would run below their personal threshold.

It was clarified that the shared credential could be set as the Monitor service account / domain identity through the ControlUp Console.

Troubleshooting an On-Premises 8.7 Issue with SOP Not Functioning

Posted on

A customer upgraded their On-Premises environment from 8.5 to 8.7 and introduced SOP 8.7, however it was not functioning. Possible fixes such as restarting ControlUp Monitor and SOP, changing the SSL cert, toggling "Ignore SSL Cert Errors", checking port 443, checking UserManagement logs, checking docker logs, creating a monitor log (Log4Net) and generating the key file again were suggested. They would also benefit from visiting https://support.controlup.com/v1/docs/cop-87-security-enhancement-for-monitor-sop-communication for further instructions.

Running a ControlUp Automated Action fails with EventID 5005

Posted on

A user experienced an error when running an automated action with EventID 5005 due to UAC being enabled. The user then ran the action as a specific user that had rights to start VMs in vCentral, and it was suggested that the action could be run from a Monitor server instead. Any logs can be shared by opening a ticket or in private with support. ControlUp has a log4net script action available to investigate this issue further. The registry key EnableLUA will be read if the script is set to "controlup console/monitor".
