[ZBX 2.2] - Regex, discovery and macros

[eljibe]

Hi all,

I'm using a File system discovery rule, on several hosts.
In the discovery, I specify the filter {#FSNAME} and I want to use a host macro for my regular expression.
Here is my regular expression:

^/DB2/MUP10/.*(_data[0-9]*|_tmp|Logiciel|Donnees|arch|log)$

It works perfectly. Except it only works for one host.
Some other hosts have exactly the same file system, BUT using the path

^/DB2/<VARIABLE>/.*(_data[0-9]*|_tmp|Logiciel|Donnees|arch|log)$

I want to use a macro here and have this regular expression:

^/DB2/{$MYMACRO}/.*(_data[0-9]*|_tmp|Logiciel|Donnees|arch|log)$

And filling the value of the macro on each host.
Is this possible ? So far I have tried and failed.
