F5 as web server

Yes.

 
 when HTTP_REQUEST { 
 HTTP::respond 204 
 log local0. "Sent a 204!" 
 }  
 

...Will go to /var/log/ltm.

-Matt

will this log be cumulative?

 

This 204 irule when invoked will send out hundreds of thousands of 204's every hour.

Yeah you probably don't want to do that then, you'll fill up /var/log very quickly. You could log to a localX facility that you set up to send to a remote syslog server, but there's not really a good way to get statistics like you are looking for out of an iRule. You could increment a counter variable each time it was sent, but I can't think of a way to periodically log that counter.

You could use the 'b rule send_204_rule stats' to view the number of times the HTTP_REQUEST event has run since the config was last reloaded. Or as Denny suggested, you could use a global variable which counts the execution time. You'd want to add logic to log the current total every X number of seconds or X number of executions (Codeshare example: Click here). Or you could use a stats profile (article: Click here). The stats is accessible via the GUI (and should be accessible via SNMP, but due to a bug, CR117258, this doesn't work in 9.4.6).
