Hello,
I need to report antivirus daily update on servers,
i have an hourly logging of each "Endpoint" with version number.
How can i count field value variation for each day and each "Endpoint" ?
It would be great if you could provide an example,
if you want the value VARIATION during the day, maybe you want the first and last of each day and calculate a variation. this would be
xxx |bucket _time span=1d|stats first(version) as first, last(version) as last by _time, endpoint|eval variation=last-first
OR do a simple delta between the last value of each day :
xx|bucket _time span=1d|stats last(version) as last by _time, endpoint|delta last as variation
Also for variation, streamstats could be your friend. And lastly : check delta blogpost
Does it help ?
In general, you can do this by
<your basic search> |bucket _time span=1d |stats count by version_number,endpoint,_time
This will give you the count of different version numbers per day per host
If you want to do it in any specific way, please provide more details (sample events,fields etc)
