Hello all,
I have a scenario where I need to make calculations regarding license consumed, per host. However, since in the license_usage log, host value was squashed and I can not fix it for past events.
My theory to calculate average license consumption per host is: 1 - Calculate license used per index, per day
index=_internal source="*license_usage.log" component=LicenseUsage type=usage (idx=set1_*)
| timechart useother=false limit=100 span=1d sum(b) by idx
| fillnull value=0
Output Example for daily license consumption:
Date
set1_index1
set1_index2
set1_index3
22-02-2022
345
354
343
21-02-2022
3463
3463
234
2 - Calculate the distinct number of hosts in each index, using tstats:
| tstats values(host) as hosts, dc(host) as total_hosts where (index=set1_*) by _time,index
| timechart useother=false limit=100 span=1d max(total_hosts) as "TotalHosts" by index
| fillnull value=0
Output Example for number of hosts per index:
Date
set1_index1
set1_index2
set1_index3
22-02-2022

ISSUE: The name of the columns is not static. I can only use a prefix, defined in the index naming conventions.
Objective:
If I am able to divide the daily license consumption by the number of hosts, I have the average consumption per host.
Doe any of you can help me find how I made divide the values in the first query by the ones in the second query, geting a similar output to the table below?
Date
set1_index1
set1_index2
set1_index3
22-02-2022
172,5

85,75
21-02-2022
865,75

Thanks in advance for your help on this issue.
