Memory utilization monitor tests free memory and triggers an alarm if it is below the given threshold or if the device is unavailable.
System type: All but Other/Unidentified
Category: Performance
On Windows devices, the methods for measuring memory 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 device is required.
When using Windows performance counters, the service “Remote Registry” must be enabled and started on the monitored device.
On Unix devices, KNM connects to a monitored device using SSH2, issuing commands specific to the selected operating system. Ensure the user used for UNIX devices can issue required commands. free -m is the default command. It may require software installation on your device.
Note: If you experience issues with this monitor type on Windows machines, try unchecking the Use WMI checkbox on the Advanced tab of the device node.

Unit - The unit of free memory tested. The free memory threshold is specified in this unit.
Process report - If checked, process memory consumption is included in the alarm message.
Inherit credentials - Specifies the Windows domain credential, if one is required. If checked, inherited. If blank, overrides the Windows domain credential set for the device on the Authentication tab of a device node.
