    OPC-UA as item source

    I have a specific piece of hardware that provides usefull system information via OPC-UA and would love to keep track of them inside Zabbix.
    Is it possible to configure zabbix to query item values from an OPC-UA server?

      It's been a LONG time since I've done anything productive with OPC, and not at all with Zabbix, but thought I'd chime in.
      OPC servers access your process control data in the (semi-)proprietary formats of the device maker and expose that data for read/write access via clients to that server. When I was using OPC productively, that meant Windows Dynamic Data Exchange (DDE) but now apparently RESTful APIs are available:

      Zabbix native REST access, or via scripts, could get you there. Here's a python scripting video:

      There's been some Zabbix community work going back to at least 2020:

      Watching this topic, and participating as much as I am able, even though my SCADA days are long behind me! I hope this helps.

          Looks like that REST API is only available if you activate it inside the OPC-UA Server. I don't have access to that server, I can only connect to it and read items. So I guess there is no native way of doing this without building an external script for translation or something..

              You connect to it how? OPC-UA in this metaphor is the server (of process control data) and Zabbix is a client to that server. By what client-server protocol are you connecting?
