Hi boyemillar! Thank you for your contribution.

Please could you tell something more about keys of items you have used in your map? How originally keys look like in host configuration page and does it match with keys used in the map? Please replace sensitive details in item keys by some fake ones.

I tried to create a host using official "Template OS Linux" template and added 4 map host elements in my map for just created host with following labels:
1) {{HOST.HOST}:agent.ping.last()}
2) {{HOST.HOST}:vm.memory.size[total].last()}
3) {{HOST.HOST}:vm.memory.size[{$TOTAL}].last()}
4) {{HOST.HOST}:vm.memory.size\\{$TOTAL}.last()}

1st and 2nd macros returned last values for each of item used in functional macro. The 3rd and 4th macros was resolved as "UNKNOWN" text as you have mentioned in description but that's how I would expect it to work. All 4 samples worked equally in 4.0.0, 4.0.4, 4.0.5 as well as in all 4.0.x versions released later. What I'm doing differently from your case? I'm wondering how it would work for you in old releases.

Hi Thanks for looking into this..

I first noticed this on our VDI map which pulls data via a template from our VMWare VCenter

On the map label for one of my items i'm using this

This is what used to work before we moved from v4.0.5 to v4.2.0

Resolved in feature/ZBX-15954-4.2

Hi Miks

I have tried the changes you made to the /usr/share/zabbix/include/classes/macros/CMacrosResolver.php and it seems to have fixed the issue for me. The Macros which were not showing are now displaying fine.

Thank you boyemillar for feedback. Good to hear that problem is solved. The fix should be included in next minor release.

Fixed in:

• 4.2.5rc1 3e869f100c7
• 4.4.0alpha1 (master) 4dfb0aa4066
