CMK version: 2.0.0:p16
OS version: CentOS 7
I have successfully converted our custom notification script to python3 
. It uses the same parameters described in documentation Notifications - via Email, SMS, Ticketsystems and more. I was hope to improve my script, but not sure how.
For example, in the print screen you see “Destination IP” and “SNMP community”, where you can enter a parameter value. I want to add an field to my customer script, so that it’s more clear which value should be entered where. Is there anybody that done this before?

Ps I come so far, that I understand that the parameters are passed in this script. /opt/omd/versions/2.0.0p16.cee/lib/python3/cmk/gui/plugins/wato/notifications.py. That it passes to the script that eventually executes.
