I am trying to do something similar and have created 2 irules, I can see log entries that the "event" is occuring, but I never see that the second irule is called. I am going to attempt to combine into a single one. Has anyone had success using the above?

Hello,

I'm not sure issues you are facing, so did you write the rule library name in front of procedure on the call statement?

e.g.

call procLibrary::sendEmail

Please, check if this short example makes more sense to you:

# Some virtual server
ltm virtual vs_devcentral {
    destination 172.30.30.101:http
    ip-protocol tcp
    mask 255.255.255.255
    profiles {
        http { }
        tcp { }
    }
    rules {
        irule_devcentral
    }
    source 0.0.0.0/0
}
# iRule with events
ltm rule irule_devcentral {
    when HTTP_REQUEST {
           log local0. "This is from irule_devcentral"
           call irule_lib_dc::externalProcedure()
    }
}
 
# Library with procedures
ltm rule irule_lib_dc {
    proc externalProcedure() {
        log local0. "This is from externalProcedure() into irule_lib_dc"
        HTTP::respond 200 content "<html><head></head><body>Voila!</body></html>" Connection close
    }
}

The test:

[root@bigipdelta:Active:Standalone] tmp # curl -v http://172.30.30.101
* Rebuilt URL to: http://172.30.30.101/
*   Trying 172.30.30.101...
* Connected to 172.30.30.101 (172.30.30.101) port 80 (#0)

Log:

[root@bigipdelta:Active:Standalone] tmp # tail /var/log/ltm
