Documentation on TEMPLATE_NAME:METRIC

[jjschultz]

I was reviewing the latest "Template Module Linux network interfaces by Zabbix agent".
In the Trigger "Interface {#IFNAME}: Link down" the Descriptions says "3. {TEMPLATE_NAME:METRIC.diff()}=1) - trigger fires only if operational status was up(1) sometime before. (So, do not fire 'ethernal off' interfaces.)"

What is TEMPLATE_NAME:METRIC ?
I could not find any documentation on this.

I assume this is a MACRO to a Item in the current Template

• TEMPLATE_NAME="Template Module Linux network interfaces by Zabbix agent"
• METRIC= ?

I am not sure what item METRIC is referencing.
I assume it has something to do with the last line in the Problem expression, based on the Description.

[FONT=Lucida Sans Unicode]{$IFCONTROL:"{#IFNAME}"}=1 and ({Template Module Linux network interfaces by Zabbix agent:vfs.file.contents["/sys/class/net/{#IFNAME}/operstate"].last()}=2 and [B]{Template Module Linux network interfaces by Zabbix agent:vfs.file.contents["/sys/class/net/{#IFNAME}/operstate"].diff()}=1[/B])[/FONT]

"METRIC" is referring to the metric that is being collected and then evaluated in the trigger, in this case "vfs.file.contents["/sys/class/net/{#IFNAME}/operstate"]".

I see the trigger expressions in the template documentation have not been yet updated to the Zabbix 5.4 format.
