Hey
I'm trying to extract the values from _time to new fields (Year, Month, Day), in order to compare average of events during current month to last 3 months, but it seems like they do not get any value.
here is my search:
'soc_events'
| search * Rule_Name="*"
| eval mytime=strftime(_time, "%Y/%m/%d")
| rex field=mytime "(\"?<Year>\d+)/(?<Month\d+)/(?<Day>\d+)\""
| stats count as Count by Year,Month,Day
| sort Year,Month,Day
| eventstats last(Month) as Current_Month last(Year) as Current_Year
| where Month!=CurrentMonth OR Year!=Current_Year
| stats avg(Count) as DayAveravge values(Month) as Months by Day
The regular expression does not match the data. Since the 'mytime' field does not contain quotation marks, they should not be in the rex
command. Try | rex field=mytime "(?<Year>\d+)/(?<Month>\d+)/(?<Day>\d+)"
.
That's not all. Once you filter out all events from the current year using | where Month!=CurrentMonth OR Year!=Current_Year
you're likely to have nothing left.
What problem is this query trying to solve?
well as i said i'm trying compare average of events during current month to last 3 months
i did few changes that helped a little :
'soc_events'
| search * Rule_Name="*"
| eval mytime=strftime(_time, "%Y/%m/%d")
| rex field=mytime "("?<Year>\d+)/(?<Month\d+)/(?<Day>\d+)""
| stats count as Count by Year,Month,Day
| sort Year,Month,Day
| eventstats last(Month) as Current_Month last(Year) as Current_Year
| where Month!=Current_Month OR Year!=Current_Year
| stats avg(Count) as DayAveravge values(Month) as Months by Day
but now the query does not compare the previous months to this one like i wanted it to
I don't see the differences in the latest query.
The events of the last 3 months will all have Year==2020 and Current_Year==2020. Therefore, they will all fail where Year!=Current_Year
and will not be displayed.
