Macros examples

[arikin]

Any real life examples of macros used in Items?

The online manual actually just a reference. Lots of facts but examples are slim. Even the macro examples in the forums come up as errors.

For example trying to make an item where the port is an user macro.

Description: TCP PORT
Type: Simple check
Key: tcp_perf,{TCP.PORT}

--> That gives the lovely error msg:
Error in item key: invalid character '{' at position 9

--> Same for : Key: tcp_perf,{$TCP.PORT}

Yes the answer may make me look like a fool. But real working... examples would help prevent stupid questions like mine. (Yes I have spent hours on the inadequate search function of this forum. By the way google finds phrases on this forum better).

Good Morning,

as you can see, you can define macros in Templates and on the host itself.
If the macros have the same name in the template and the host, the value from the host will be use.

Here is an example for an item:

Host:        Template_xy
Description: Application Availability on Port {$PORT}
Type:        simple check
Key:         tcp,[{$PORT}]
Type info..: Numeric (unsigned)
Data type:   Decimal

In the template I have defined the macro $PORT with a standard value 3181. And on the hosts where I use this template I define the correct port if it's not the same.

Additionaly under Administration you can define global macros for the whole zabbix environment. I use these for date and time macros and update them every minute with a little PHP script.

Hope this will help you.

Thank you

Ah! Thank you.

So the square brackets are actually required.........
tcp,[{$PORT}]

Please forgive me. When a unix man page uses square brackets it means a range of values that can be used for that parameter. That is why I tried these:
tcp,{$PORT}
tcp,$PORT
