Although NetCollector reports are customizable to some extent, I don't think we offer IPSLA or Juniper RPM metrics under NetCollector reports. Your best bet would be to use NetPlanner capacity reports which are customizable and support IPSLA and Juniper RPM data. The other option would be to view this data in Portal and create a report for that dashboard. In either case your options to customize are limited.
To continue on with Hemant's statement - view the NetCollector reports as more of an inventory assessment than a performance reporting tool. The majority of reportable items are derived from SNMP acquired metrics which formulate (and populate) the attributes of a node model.
Portal/NetPlanner are your best options to extract this information in a single point.
