Hi Phani,
In CA UIM Snap we have the option for adding the custom monitor by adding the specific OID values for monitoring purpose.
The profile is created in SNMP Collector Probe.
I had followed the below procedure.
1) I had collected few OID values for which I had to monitor for the device.
2) Created a new custom monitor added the fields also I wanted to populate values in percentage so in value section I had mentioned % .
3) In the profile created I had added that custom monitor.
But when I had checked in the Reports section for the custom monitor I am unable to find that.
I will also attach the images which can helpful for your reference.
Regards,
Sumeet Mishra
