Hi,

How to alert when http status=404 is over 5 percent of total traffic ?

This is the simple search query I use. Need your help to add the correct condition for the alert.

tag=NginxLogs  host=www* status=404

Thanks for your help.

Try this

tag=NginxLogs host=www* |stats count by status|eventstats sum(count) as total|eval perc=round((count/total)*100,2)|where status="404" AND perc>5
Happy Splunking!

you can also achieve it using below query:

tag=NginxLogs host=www* status=404

| stats count by status
| eval total=[search tag=NginxLogs host=www* | stats count(src) as total | eval total="\"".total."\""| return $total]
| eval percent=round((count/total)*100,2)
| where percent>5

In my environment, this query ran faster.

you can be more efficient if you mention index=xyz in your query. (in our case we did)

Thank You!

Can you explain where do I add it in order for that to be an Alert?
