in need of help for my first Zabbix trigger :(

[chavv]

Hi, I am trying to make a trigger for IIS port.
I want it to be checked from the agent running on the same machine.
IIS is listening on ports (say), 7028 (http) and 8443 (https)
After applying App IIS template I get a trigger checking for port 80(disabled on machine) - but no matter what I try i can't make it check for other port(s)

original trigger is called: Template App IIS by Zabbix agent: IIS: Port {$IIS.PORT} is down
expression is: "net.tcp.service[{$IIS.SERVICE},,{$IIS.PORT}]"

I tried changing the defined value of $iis.port (by changing value of the macro), - no success
tried writing 7028 instead of $iis.port eg
"net.tcp.service[{$IIS.SERVICE},,7028]"
result:

Cannot add trigger

• Incorrect item key "net.tcp.service[{$IIS.SERVICE},,7028]" provided for trigger expression on "MyHost".

I simply want to check 2 other ports instead of 80. Surely its very simple
Thanks

Hi,
I've managed to simply change the value of IIS.PORT as on the screenshot and it works. Please go to Configuration -> Hosts.

If you would like to monitor two services, I suggest adding a second set of macros, let's say named {$IIS.SERVICE2} and {$IIS.PORT2}, one item and one trigger.

Clone item "IIS by Zabbix agent: IIS: {$IIS.PORT} port ping" and change the key to the proper macros.

Then clone trigger "IIS by Zabbix agent: IIS: Port {$IIS.PORT} is down" and change the expression.

Works in Zabbix 6.0.
This is how generated alarms will look like.

Thank you very much for detailed explanation! I was completlely missing the part where first must make "item", then clone trigger!
I was able to make checks using

{MyHost:net.tcp.listen[7028].last()}=0

but all my attempts to use the tcp.service end giving "down" state, eg:
"net.tcp.service[{$IIS.SERVICE},,$IIS.PORT]" , even when trying to use [http,,80] or any combination of $IIS.SERVICE , $IIS.PORT and number. But it could be that something was messed up, before asking here

as this is still a "test" setup /test zabbix server and test machines/ , I will start from scratch and think should be ok now - after getting some basics... and probably going to read bit more of documentation before jumping into the fire

Thanks a lot
