Howto use item as trigger function argument

[jcesario]

I would like to do something like this. However zabbix keeps throwing a syntax error at me

{Template_MySQL50_Repl:mysql50.repl[Relay_Log_Pos].last(0)}>65536 & {Template_MySQL50_Repl:mysql50.repl[Master_Log_File].str({Template_MySQL50_Repl:mysql50.repl[Relay_Master_Log_File].last(0)})}=0

* Incorrect trigger expression. [ ... & {Template_MySQL50_Repl:mysql50.repl[Master_Log_File].str( ... ]

bump? Could use some help with this.

It is not supported.

Seriously 0.o ? That seems like such a common thing to do. Compare two dynamic strings against each other...

Any idea when it may be supported? I'm using this to look for servers that will die soon because of full memory timeleft(//vm.memory.size[available],3d,0) - which is fine - mostly. But I want to do it for all the server's uptime, perhaps minus 10 minutes for bootup and stabilisation, like timeleft(//vm.memory.size[available],system.uptime-10m,0). However, I can't find a way to do that. How can I?
