cpu metrics not visible.

Issue/Introduction
We have discovered few devices in snmpcollector probe and for these devices the all available CPU metrics are not shown. We can only see below metrics for these devices:
- CPUUtilizationLast5Min
- CPUUtilization5Min
- CPUUtilizationLastHour
Though we have enabled other CPU metrics In the template, we only see above 3 metrics for these. There are other devices of similar make and model and for them I can see all metrics.
Environment
Release : 9.x, 20.x
Component : UIM - SNMPCOLLECTOR
Resolution
The issue has been replicated in-lab. Please find our findings as follows:
Environment Details:
================
- UIM 20.3.3 with snmpcollector 4.04
IP Addresses used:
================
1) 192.168.5.26 -> this is the IP Address of working Windows device
2) 192.168.5.39 -> this is the IP Address of simulation from your non working device with issue
Note: the same template has been used with all CPU metrics enabled and deployed on the above two devices
Observations:
============
1) Observations made on 192.168.5.26 (working device):
-> the metrics available for the device in Operator Console:
-> From snmpcollector -> configure -> Profiles -> Expand 192.168.5.26 -> the following metrics have been discovered:
- Running Vendor Certification test on CPU:
-
- Output of Vendor test:
- Observe the above output contains entry for hrDeviceStatus, whose OID is 1.3.6.1.2.1.25.3.2.1.5.2

- Observe the number of metrics which depend on hrDeviceStatus
- Running snmpget on the OID 1.3.6.1.2.1.25.3.2.1.5.2 for verification:

- Observe in the snmpget output on the OID 1.3.6.1.2.1.25.3.2.1.5.2, we get Value=2
2) Observations made on 192.168.5.39 (non-working device):
-> From snmpcollector -> configure -> Profiles -> Expand 192.168.5.39 -> the following metrics have been discovered:
- Running Vendor Certification test on CPU:

OID=.1.3.6.1.2.1.25.3.2.1.5.2
Type=<Unknown>
Value=
- Observe in the snmpget output on the OID 1.3.6.1.2.1.25.3.2.1.5.2, we do not get Value= output, it is blank
Conclusion:
- Snmp Manager (which in this case is snmpcollector probe) just displays the results it fetches from the snmp agent
- The OID 1.3.6.1.2.1.25.3.2.1.5 with instance 2 (i.e. 1.3.6.1.2.1.25.3.2.1.5.2) does not output value. We have seen the issue with two tools:
(1) snmpcollector probe
(2) snmpget utility
- From the above observations, it is evident the the SNMP Agent on the end device with issue does not output the value for hrDeviceStatus, whose OID is 1.3.6.1.2.1.25.3.2.1.5.2, this is the cause of many missing metrics in the environment
- The customer would need to check with the Vendor on the cause of missing value for OID 1.3.6.1.2.1.25.3.2.1.5.2.
- The issue is with the snmpagent not providing us the value for 1.3.6.1.2.1.25.3.2.1.5.2 - may a reinstall / upgrade snmpagent on the end device is required, the vendor should be the right person to guide on the cause of the issue
