So that dashboards are getting wrong information Splunk enterprise security app. Please help me where I did mistake.
The values() option only gives you each value once.
If signature exists more than once, it's only contained once in the result (like an implicit dedup). Therefore, you might less results than by simply counting them.
Use list() instead of values(), that should fix it.
