The Spectrum Inside view in Grafana viewer is only showing 5 SpectroSERVERS. The logs show that it gathered SSPerformance models for only 5 SS when there are 12.
The REST query used to populate the SpectroSERVER hostnames had a throttle limit of 5.
Release : 20.2
Component : Spectrum Core / SpectroSERVER
Needed to use the fixed InsideView executable in patch Spectrum_10.04.01.PTF_10.4.111
This will be fixed in NetOps Spectrum 20.2.5
