Hi guys,

I need to create this alert that will fetch failed logins that happen more than 3 times within 15 minutes and display the results as user and the number of events per that user.

I am thinking using something like:

index=indexName eventtype="failed_logins" | bucket _time span=15m

or

index=indexName eventtype="failed_logins" | tranactions <something?> maxspan=15m

Anyone experts can give me some guide?

hi normangoh,
write your query

 index=indexName eventtype="failed_logins" 

and backup simply as an alert with the following characteristics:
alt text

when your research to see all the results, you can use the following query:

 index = indexName eventType = "failed_logins" user = * |table  user  _raw
