We are monitoring Microsoft Dynamics NAV instances by the Zabbix. And use LLD for discovery of list of NAV services.
Basically the service name is representing like: "MicrosoftDynamicsNavServer$Instance_Name" where "MicrosoftDynamicsNavServer$" is a constant value and "Instance_Name" is variable.
The problem is with displaying of NAV services names in "Monitoring"-"Overview" (see ) and "Hosts"-"Items" (see ) where the name of instance is starting from digit.
If NAV service instance have digits (2-9) after "$" symbol in the name then it is showing incorrectly (symbol "$" is omiting). Especially if this digit is 1. Then it is repeating several times. As you can see in right side of picture item keys are representing correctly. But its names are showing wrong in the lists (look at left side of and pictures).
Examples of LLD setup you can find in the attached pictures:
