I am having ITSI 411.
and have Configure multiple ITSI deployments to use the same indexing layer.
Initially, I had not enabled backfill on KPIs , the services row in the service analyzer was empty. After enabling backfill at service level the service started appearing. that meant enabling backfill populated kpiid=SHKPI-XXX and with attribute isbackfilledevent=1.
backfill at service level is newly introduced in 411
What I understand in general is that servicehealth scores should be computed, why its not computed in 411 which should be of attribute isbackfilledevent=0.
And the behavior of not displaying any services (- No results found) and Health scores ( kpiid=SHKPI-XXX) not computed to summary indexes even for one working before suddenly without any clues in internal logs is worrisome.
