xeeshanmohsin,
Can you share the details of the external monitor that you have created to check the Syntax.
You are seeing an error similar to the following in /var/log/gtm:
gtmd[<PID>]: 011a4003:1: SNMP_TRAP: Pool /Common/<pool> member /Common/<virtual_server> (ip:port=<ip_address>:<port>) state change green --> red ( Monitor <monitor> from <ip_address> : missing program name)
You may also see the monitor provide results other than what you are expecting.
Environment
- BIG-IP GTM, DNS, or Link Controller
- External Monitor
Cause
This error can be caused in two ways:
- You've configured an external monitor on the GTM and didn't put the program name in the program name field
- You've created it with a program name, but didn't import the external monitor script into the GTM yet
Recommended Actions
Apply the proper program name or import the proper program file into the device when creating the monitor.

Check the permissions on the monitor, should be be read/write/execute by root.
If it's a production unit, I recommend to do it in a maintenance window.
Or, you may want to work with F5 support?

MVPI do not renember if the script should also be added on all F5 devices in a DNS sync group or prober pool to be used just so only the GTM with the script to do the job?
xeeshanmohsinscript is added to both GTM in the sync group

What about LTM ? The GTM can delegate the probes to the LTM devices 😀
