Monitors CPU utilization on an asset and triggers an alarm if above the specified threshold.
System type: All but Other/Unidentified
Category: Performance
On Windows assets, the methods for measuring CPU utilization is WMI or Windows performance counters.
For WMI or Windows performance counters, a Windows user with permissions to read the registry on the monitored asset is required.
When using Windows performance counters, the service “Remote Registry” must be enabled and started on the monitored asset.
On Unix assets, KNM connects to a monitored asset using SSH2, issuing commands specific to the selected operating system. Ensure the user used for UNIX assets can issue required commands, like vmstat or mpstat. If required, install the system tools for your system that include the mpstat utility to monitor specific CPUs or cores. Otherwise, only overall system load will be monitored.
Note: If you experience issues with this monitor type on Windows machines, try unchecking the Use WMI checkbox on the Advanced tab of the asset node.
Max CPU load - The maximum CPU utilization in percent.
CPU number - The number of the CPU on the host. This value is usually automatically obtained from the relevant asset. To refresh the list, press the Rescan CPUs link.
Detailed error report (Windows only) - If checked, includes the top 5 processes by CPU usage.
Inherit credentials - Specifies the Windows domain credential, if one is required. If checked, inherited. If blank, overrides the Windows domain credential set for the asset on the Authentication tab of an asset node.
