Anzine321 Did you copy and paste the iRule because it seems that based on your spacing that you might have typed it out and missed something along the way.

      iCall is just a scheduler, it's pretty much a crontab job that will "survive" upgrades and reboots since it's coded into the configuration files. 

      Use tmsh show sys icall to display the runtime info, like this: 

       

      ----------------------------------------------------
Sys::iCall::Periodic Handler: *****-scheduler
----------------------------------------------------
Number of times handler signalled 15.4K
Number of times handler ran 15.4K
Creation time 06/16/23 16:38:15
Current status active
Time since last status change 06/16/23 16:38:15

       

      In the article you provided, it runs this command: exec perl /shared/scripts/vpn_ccu_monitor.pl

      - This files needs to exist, and as the article says it should have the execution permissions (chmod +x) 
      - You should try to run this script manually at least once, before attempting to schedule it. This way you'll see if it runs properly, or if it returns errors. 
      - One thing I noticed, the script calls for the #!/usr/bin/perl -w interpreter. 
      I know that the perl interpreter was moved to /bin/perl in more recent versions (run which perl to find it), as I've had to correct this syntax on multiple scripts I was using. 
      - I'm not sure if the script returns anything into output. It's a good idea to add some "echo $variable" commands during the debugging, to confirm everything works properly.
