I'm new to splunk queries and how to create an alert using Linux commands on Splunk?

[Vin]

I need to write a Splunk alert to check number of connections on a server. Using below Linux command I can get the results on the server. But help me out in creating an alert on Splunk with the command.

ps -ef | grep '[s]shd' | grep -v ^root | grep -i file* | wc -l

That's a pretty straightforward query in Splunk.  However, do you have the equivalent to "ps -ef" logged in Splunk?  If not, then the alert won't work.

Another option is to create a scripted input that executes that CLI command and logs the result in Splunk.  Then you can alert on it.
