Exclude kernel memory utilization from monitoring in Performance management

[Purneswara Rao Konda]

Hi Community,

Is there a way to exclude kernel memory of devices from monitoring and Memory Utilization dashboard in performance management? Please suggest

Hi Eshwar,

Portal dashboards renders the metrics captured from the devices. If the Memory metric includes the kernel memory you need to change the current Vendor Certification to create a new metric without the kernel memory or identify if there is already a metric providing that information

What is the Vendor Certification of the Metric Family?

Hi Jose, Thank you for response.

We have two kind of vendor devices such as Cisco and Aruba. When I look at the vendor for Memory metric family the below list is associated with Metric family.


when I drilldown into Cisco Memory, I could see the no Metric expression for "cpu memory reserved for kernal usage". Does that mean Kernal memory excluding in Memory utilization?

Hi Eshwar,

when a Vendor certification has no Value Expression for a Metric, it means the Vendor certification does not implement that metric

Cisco Memory Vendor Certification uses CISCO-MEMORY-POOL-MIB but there isn't any OID that offer what you are looking for.

The only 2 VCs that gather memory used by kernel are these ones, but they seem to not be supported by your devices because even they are in a higher priority your devices are using Cisco Memory

With that said, I would talk to Cisco to ask if there is any OID supported by your devices providing the information you are looking for. If there is, then we could make a recertification or Vendor Extension

If there's nothing written on the Metric Expression column, it means that the value cannot be reported by the selected Vendor Certification. Those that have something written can be reported upon (metric name being the reported parameter name).
