 Description   

The agent protocol for passive checks is simple and efficient, but at the same time it's very difficult to extend. Especially, when it comes to preserving compatibility with some very old agents. We should create a better, JSON-based protocol for passive checks (used by the new agents in 7.0) but keep support for the old protocol intact. One way to do it is to replace item key with the new JSON struct but fall back to the old proptocol if the agent returns error about invalid key format.

I see the request data is a list of items, and so is the response from the agent. But there are no item keys in the response list.

Is it expected that data for multiple items is returned in the same order as requested, or is it expected that only one item is ever requested, even though it is a list?

It's for future use markkul

I guess this change caused ZBX-24600.

Comment by Marina Generalova [ 2024 Nov 13 ]

Currently, documentation does not mention that as a result of this change, Zabbix get utility now returns the exit code 1 for unsupported item keys. The documentation will be updated in ZBX-24600.
