Hi

I have two indexes.  
One with data from our Windows servers and another with information from our CMDB.

I want to make a count of servers that have send data to Elastic within the last 24 hours from the Windows index and divide that count with a count of servers in the CMDB index

Something like _((Count of active servers in Windows index / Count of Servers from CMDB) \* 100) = “% of know servers that did send data”_

I haven’t found any way to do it in Kibana, but being new to Elastic there might be other ways to this.

Best regards  
Per Bejder

You can create an index pattern which includes both indices (`windows-data,cmdb-data`), then create a visualization which filters on the `_index` field). You can calculate the ratio using Lens formula: [Create visualizations with Lens | Kibana Guide [7.16] | Elastic](https://www.elastic.co/guide/en/kibana/current/lens.html#lens-formulas)

`unique_count(server.id, kql="_index:windows-data")/unique_count(server.id, kql="_index:cmdb-data")`

Thanks - I will test that
