User macro in trapper item does not expand

[hansv]

Hi there,

I've setup a template with a user macro like so:

{$PROCNAME} => zabbix_agentd

In the template I've created a couple of items. One is of type zabbix-agent, having this key:

sw.proc.status.procname[{$PROCNAME}]

This fires a script that is defined as a UserParameter. The script does some work (gathers stats in /proc for a process (zabbix_agentd, in this example)) and sends data back with zabbix_sender.

The rest of the items in the template are set up as type zabbix-trapper, like so:

sw.proc.utime[{$PROCNAME}]
sw.proc.rss[{$PROCNAME}]

Now, the sw.proc.status.procname[{$PROCNAME}] expands to sw.proc.status.procname[zabbix_agentd], according to the server debug log.

As soon as it queries the client, the client sends its data, like so:

- sw.proc.utime[zabbix_agentd] 168
- ...

The server responds with:
info":"Processed 0 Failed 9 ...

I suspect that the macro isn't being expanded here, as I thought it would.

When I change this item to:
sw.proc.utime[{$PROCNAME}]
to this:
sw.proc.utime[zabbix_agentd]

The server responds with:
info":"Processed 1 Failed 8 ...

So, it does work when the key parameter is set to a static value, instead of a user macro.

Is this intentional, or am I hitting a bug?

Edit: I'm using v1.8.4

Cheers,
- hans

I'm seeing the same issue on 2.2 still - did you get any resolution to this?

Works here , both in 2.0.10 and 2.2.1

(just a question: you are not using {$PROCNAME} within your script, right? What happens if you send the value manually via "zabbix-send"?)

Not the OP, but I raised a ZBX bug about this, and it got marked as a duplicate of a previous Won't Fix ticket.

https://support.zabbix.com/browse/ZBX-7925

As you can see by my examples, I manually send with zabbix_sender and item with key trap.test[macro] with the server trapper item key trap.test[{$MACROTEST}] and {$MACROTEST} = macro in the host user macros.

on the ticket, richlv suggests using LLD instead, so I am making my script emit the nessicary JSON items that it will later populate with zabbix_sender...
