group fields in search command

Contributor

i would like to send an alert when newwork interface is down more than 3 min. That is to say i wanna group the field named "Status" together which value is either up or down, and the time difference is within 3 min. Now if i use "%LINK-3-UPDOWN"... | transaction host, interface | where eventcont%2!=0 per 3 min. but it have problems when e.g. down event is at 2:50 and up is at 3:10 (scheduled search is at 0:00,3:00,6:00...) even covering the search time range still exists this problem. any other best way to do this? thanks and regards,

In general you'd want some overlap in your search. So, if your search runs at 0:00, 3:00, and 6:00, you wouldn't want the search to only look back 3 hours. You'd want to look back maybe 3 hours 15 minutes.

However, that won't completely solve your problem because the outage could be days long. Maybe you could add something like this if there's no up event?

... | eval do_alert=if(now() - _time >= 180, "True", "False")

And then on the schedule set the alert to a custom condition of:

search do_alert=True
