You can get rid of the trailing numers using the PTF.RenameSensors tool.
Get rid of the trailing numbers in a sensor name
The Renaming Rules allow you to get rid of the trailing numbers in all your sensor names.
Sensor names like “PING 2” and “HTTP 1” will be renamed to “PING” and “HTTP” in one batch.
Do you want to rename all your “PING”, “PING 1”, “PING 2”, “ping” and “Ping” sensors to one universal name like “PING”?
PTF RenameSensors finds them for you and renames them according the Renaming Rules that you can set yourself.
