To monitor TACACS you will need to use an External Monitor, which is just a monitor that triggers a script to run and output tells the monitor to mark the Pool Member as Up or Down (see LTM External Monitors and K7444: Requirements for external monitor output for more info and examples).

 

If you have a perl script that will work than upload to the F5 from System ›› File Management ›› External Monitor Program File List then create a new Monitor, setting the type to External and select the script you have uploaded and any other configuration parameters.

 

You might need to read through the start of the script you have to see if you need to pass any Arguments/Variables in to get the script to work correctly.
