Solution

1. Check for the following common issues: 
   • Syslog, traps, or NetFlow traffic that may be thrashing the endpoint. 
   • Debug logging may need to be deactivated or turned off. 
   • Use Process Explorer to see if there are threads consuming CPU cycles. 
2. If the issues above were not the source of the problem, gather extended logs and send them as zip files to NinjaOne Support for resolution.

If you need help gathering the logs, please refer to the process below: 

Collect Logs

1. Open the endpoint's control panel to edit the system environment variables. You can easily find this by typing "environment" into your system's search tool and selecting the control panel option.
