We are running ITSI on a dedicated Search head running 16 cores cpu , 23 gb RAM and about 150 gb disk. It's searching an Index Cluster serving a SH Cluster and two stand alone search heads.
We have about 400 services with 3-5 kpis each. The majority of these services have been created by import through search and mass produced. They have all worked fine. However, when we try to add more services, from a specific search, we are getting NaN for each KPI and ServiceHealthScore. We have removed backfilling on the service KPIs and set static thresholds. The skipped search rate is very low,( 1,34%, 66 searches) But the new services (138) all are missing values. When the service is opened up in deep dive and summary index turned off, we get data for the entirety of kpis. The Kpis use stats sum and count.
We turned up the
max_size_per_batch_save_mb = 100
Our ITSI_backfill is at 49 mb. we are not using Backfill on these services/kpis so that should not be the problem.
So I am wondering two things,
How does ITSI create the services and Kpis from search?
How do I reload a service and its kpis?

We had same issue ,when data fetches from summary index it shows no data but when disabling Summary Index it works.
Our problem resolved by adding more roles to admin.Try to play around roles and check if the serach works with Summary.
try to add all app_admin and user.
