Memory utilization monitor tests free memory and triggers an alarm if it is below the given threshold or if the asset is unavailable.
System type: All but Other/Unidentified
Category: Performance
On Windows assets, 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 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. free -m is the default command. It may require software installation on your asset.
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.
Free memory - The amount of free memory required. If the free memory goes below this value the monitor fails the test.
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.
Task Manager approx - If checked, calculates memory utilization using a method that approximates Windows Task Manager values. If blank, uses a legacy Network Monitor method.
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.
