API: how to get a trigger based on the expanded expression?

[Mojah]

Hi,

I'm using a query like this (simplified by zabbixapi in ruby):

result = zbx.client.api_request(
      :method => "trigger.get",
      :params => {
        :filter => {
          :expression => "{13360}#0.2"
        },
        :output => "extend",
        :expandExpression => true,
        :expandDescription => true,
      }
    )

The above works, as I refer to the expression in the 'short' unexpanded version of '{13360}#0.2' where {13360} is the ID that refers to an item.

However, I would like to use this way:

result = zbx.client.api_request(
      :method => "trigger.get",
      :params => {
        :filter => {
          :expression => "{hostname:nginx.config_version.last(0)}#0.2"
        },
        :output => "extend",
        :expandExpression => true,
        :expandDescription => true,
      }
    )

In the last example, the :expression contains the full expression that would also be visible in the WebUI. However, I can't find a way where this epxression filter would yield any results.

Does anyone have any idea? Or is the :expression parameter only supporting the short, non-expanded, version?

There's currently no way to retrieve triggers by expanded expression. Filter parameters only accept values as they are stored in the database, and expressions are stored in a "compact" format.
