Is there any clamp for Predictive Insight(PI)?

Environment

DX OI 2x onpremise

Resolution

1) There is a clamp of 50k metrics for Predictive Insight 

Make sure to configure and enable the most relevant and important metrics only

2) You can increase the default clamp by adding the below environment variables in the doi-pi-projection deployment
 
  ES_METRICS_METADATA_SEARCH_LIMIT =50000
  ES_METRICS_METADATA_SEARCH_LIMIT_OVERRIDE in case we want to override it.
 
3) Important Notes:
 
- ES_METRICS_METADATA_SEARCH_LIMIT is used to set the default limit for all tenants.
- The increase of the default clamp will have some performance impact
- You will also need to increase  the cpu cores and memory allocated to the doi-pi-projection deployment
