I am not sure what version broke this but I believe it was around 8 or 9. I used to be able to use the symbols < or > in naming sensors. What I do is use them to "point" where backbone links on my switches go to. e.g. "Switch1 port x -> Switch2 port y". However, ever since upgrading to version 8 or 9 it replaces > with ] and < with [ so consequently "Switch1 port x -> Switch2 port y" gets changed to "Switch1 port x -] Switch2 port y" which looks stupid because it no longer looks like a pointer. So why does the software replace symbols < and > with [ and ] ?? What is really bizarre is all the sensors I created prior to the upgrade still have the > symbol. It is only new sensors I create that have > changed to ].

During "hardening" our software against malicious exploits like Cross-Site-Scripting-Attacks and similar stuff we had to implement a mechanism that replaces all < and > and a few other potentially hazardous characters from all form fields that users can enter into the software.

You can use characters #171 and #187 « » (in the object name edit field hold the left ALT key and enter 0171 resp. 0187 on the numeric keypad).

Or use "charmap.exe" of your windows installation, select character u+2192 and click copy, then paste into PRTG's webGUI.

THANK YOU SO MUCH!!! Although on my computer #174 and #175 produce the characters you mentioned. I consider this closed. Thanks for the excellent tip.
