How to add Quality of Service in navigation panel under SLM in USM?
You don't need to add QOS in the SLM, this is just the place to maintain (delete, export) QOS definitions in the UMP.
When you enable QOS metrics in a monitoring profile or probe, the qos definition will show in the list in SLM.
Does this help ?
If not, let me know what you are trying to achieve.
I don't have QOS option visible in the USM. I want to delete the QOS data of few servers which has been decommissioned from infrastructure.
The Quality of service tab is in SLM ( this is a portlet in UMP which you have to add) , not in USM.
In the SLM Qos section you can perform your Qos data maintenance.
