Spectrum Performance View / Spectrum Health View does not show all DSS (landscapes) health information.
In 10.4.2.0 and earlier, InfluDB does not support DSS with more than 6 landscapes. Some landscapes will not show in InfluxDB and therefore, no data for Grafana Dashboards for those DSS servers.
Release : 20.2
Component : Spectrum Core / SpectroSERVER
This is a known issue resolved in 10.4.3:
This is also resolved in PTF patch 10.04.02.01.PTF_10.4.2.112a. This patch has multiple fixes and is required to install on both SpectroSERVERs and OneClick servers. If you wish to obtain this patch in lieu of full upgrade, please contact Broadcom support.
