API get trigger. What's in the expression?

[jefftang]

What I do a trigger.get through the api, the expressions that come back look like:

{26009}>0

instead of

{hostname:mykey.last{0}}>0


it does not seem to correspond to an itemid. What is that number? And how do I get an expanded expression. I'd rather modify the api call to have it expand it, but I'll look it up if I have to.

{26009}>0

That is a reference to the function table. When the Zabbix server comes across that item it will reference the function table looking for function 26009, and it's last value, which is then substituted in and the statement is evaluated.

Have you tried adding the parameter "select_fuctions":"extend" or "refer" to your query? Looking at the docs this might give you what you are looking for. Otherwise there does not look to be a way to do this right now with the API.

Thanks for the pointer. select_functions and select_items really give me what I want, which is the itemids associated with the triggers.

Cool, glad to know it worked.
