I have created a template which contains running an external script to check if a route change has been detected.
We use redundant connections and want to monitor which connection is the active one. Therefore a script checks wich of two given IP addresses is found in a traceroute output.
The following macros have been added in that template:

{$IPROUTE1}
{$IPROUTE1NAME}
{$IPROUTE2}
{$IPROUTE2NAME}

The result of the external script can be:
0 = error
1 = route 1 active
2 = route 2 active

I wanted to use “value mapping” to translate the result to a more human readable result to show in “latest data”.
Therefore I created this value mapping in the template:

equals 0 = Error
equals 1 = {$IPROUTE1NAME}
equals 2 = {$IPROUTE2NAME}

At some host I have these macros defined:

{$IPROUTE1NAME} = Glasvezel
{$IPROUTE2NAME} = NLIX

The result is that in latest data of the host this is shown when route 1 is the active one:

{$IPROUTE1NAME} (1)

instead of the wanted/expected:

Glasvezel (1)

Can it be made possible to use macros in value mappings?
