OpManager provides you the information on the processes that are currently running on the managed device. For this, OpManager uses the protocol of the default credential of that device (SNMP / WMI / CLI).
To view the details, navigate to the Snapshot page of the device from the Inventory, and you can view all the processes that are currently running on the device from the Active Processes tab.
Also, if you have enabled Custom Dials for your devices, you can view the top 10 processes of a device by clicking on the Process Diagnostics icon on the top-right corner of the dial. From there, you can choose to end processes that are consuming a lot of resources by simply clicking on the Kill Process (bin) icon.
