Splunk Search

Top 10 ip addresses denied over last 7 days

Trying to write a search that will show top 10 "repeat" offenders over last 7 days. I'm guessing an eval(if) statement but not really sure. Only want to see repeat srcip's, not IP's that only get denied during 1 day.

Any help would be greatly appreciated.
Thanx

Try this. It will give you the top 10 repeat offenders, but depending on your data they may all be on the same day.

'... | stats count(_time) AS Occurs by src_ip | where Occurs > 6 | top limit=10 Occurs,src_ip | ...'

How 'bout this then?

index=yourIndex sourcetype=yourSourceType earliest=-7d@d | eventstats dc(date_mday) as days by src_ip | where days > 1 | top limit=10 src_ip

Would (date_mday) work better than _time to make sure it is only counting the days rather than time entries?

No, it works but need only IP
s with date returned if they have been denied more than 1 day over search period
