Splunk Search

How to edit my search to find the time frame window with the least amount of events?

New Member

Hi there,

I am trying to return the top 3 results of three hour windows where an event is least likely to happen based on the past 30 days during working hours (Monday - Friday 9am - 5pm).

So far I have

event name here
 | eval day_of_week = strftime(_time,"%A")
 | where NOT (day_of_week="Saturday" OR day_of_week="Sunday")
 | bin span=1d _time
 | stats count dc(_time) as days by day_of_week
 | eval average_count = count / days
 | eventstats avg(average_count)
 | sort Average_Count | head 3
 | fields day_of_week, count

I am looking to return something like:
Example: Monday 9am - 12pm, Monday 2pm - 5pm and Friday 2pm - 5pm.

An ideas how to improve my search and return what I am looking for? Cheers

Try like this

your base search
| eval day_of_week = strftime(_time,"%A")
| eval hour=strftime(_time,"%H")
| where NOT (day_of_week="Saturday" OR day_of_week="Sunday") AND (hour>=9 AND hour<17)
| eval period=case(hour>=9 AND hour<12,"9 AM to 12 PM",hour>=12 AND hour<14,"12 PM to 2 PM",1=1,"2 PM to 5 PM")
| bin span=1d _time
| stats count dc(_time) as days by day_of_week period
| eval average_count = count/days
| sort 3 average_count
| eval day_of_week, period, count

Thanks so much.

However, I would like to return the top 3 x 3 hour time slots with the least amount of events not specific to line 5 in your suggestion.

Something like this instead:

 your base search
 | eval day_of_week = strftime(_time,"%A")
 | eval time= strftime(_time,"%m/%a")." ".strftime(_time,"%H %p")." - ".strftime(Max,"%H %p") 
 | fieldformat Max=strftime(Max,"%m/%a %H:%M")
 | tstats count latest(_time) as Max WHERE index=_internal BY _time span=3h
 | where NOT (day_of_week="Saturday" OR day_of_week="Sunday") AND (hour>=9 AND hour<17)
 | stats count dc(_time) as days by day_of_week period
 | eval average_count = count/days
 | sort 3 average_count
 | fields day_of_week, period, count

However, the above does not seem to work, can you help me out? Cheers
