Doesn't matter

it would be very useful, especially for clouds

Happy with the auto-registration functionality in 2.0.2 but this would be a significant improvement when using Zabbix to monitor elastic cloud hosts and applications. Same for snmp/impi.

Maybe run script action as well? you could run external code that hits the API to do anything you want then.

i need this feature too. auto add snmp and impi interface!

There has to be a option using which we can enable SNMP, JMX interface on auto registered hosts..

I need this as well. Specifically the SNMP interface in my case. The snmp based templates I used to auto link in 1.8 now are not able to be linked which, in my case, breaks all the templates assignments because the snmp template was linked with the main "default" template being linked during the auto reg process.

This should not be considered just an improvement requests. Auto linking broke from version 1.8 to 2.0 for people who auto link snmp templates. It's a regression.

Support. This is a very useful functionality.

This was also a significant problem for us because of auto-linking. Because we have templates with items which need JMX, auto registration failed to link ALL templates, not just the items (or at the very least, the templates) that need JMX. So the host would get added with no monitoring at all.

I ended up fixing this by adding a database trigger to auto add the JMX interface when the Agent interface is added. This allowed the auto-registration with template linking to work. Yes it ends up adding a JMX interface to all hosts, even those without JMX, but unless a monitoring item tries to use the JMX interface, nothing complains.

Below is the trigger for anyone interested in it. It's made for postgres. You'll likely need to change the port from 9810 to your JMX port:

CREATE OR REPLACE FUNCTION interface_create_jmx() RETURNS TRIGGER as $$
  BEGIN
    IF new.type != 1 OR new.main != 1 THEN
      RETURN NULL;
    END IF;
    BEGIN
      INSERT INTO interface (hostid,main,type,useip,ip,dns,port,bulk, interfaceid) SELECT new.hostid, 1, 4, new.useip, new.ip, new.dns, 9810, new.bulk, nextid+1 FROM ids WHERE table_name='interface' AND field_name='interfaceid';
      UPDATE ids SET nextid=nextid+1 WHERE table_name='interface' AND field_name='interfaceid';
    EXCEPTION
      WHEN unique_violation THEN
        -- do nothing
    END;
    RETURN NULL;
  END;
$$ LANGUAGE plpgsql;

CREATE TRIGGER interface_create_jmx AFTER INSERT ON interface
  FOR EACH ROW EXECUTE PROCEDURE interface_create_jmx();

+1 we really need this for SNMP/JMX monitoring of auto-registered hosts.

Back in early 2013, we were almost forced to move off Zabbix due the feature-breaking change back when 2.0 was released. We had to develop an external automation system that used various API calls just to allow auto-registrations to continue to work with SNMP linked templates.

It's sad to have to used a kludge just because we chose to use linked templates.

Used a setup similar to what Patrick did, but we use the zabbixapi gem to workaround this for now. Requires a script that fires during auto-registration to determine the system type, add the JMX interface, and then has to apply the templates with JMX items afterwards.

Would really streamline our process to have JMX interface and templates applied without needing the separate actions/scripts.

This would be useful functionality in a large cloud environments hosting Java applications. Especially if you link templates to hosts matching certain auto registration criteria (for example: HostMetadata contains string "Cassandra" or "Elasticsearch"), you end up in a situation where adding JMX interface has to be done either manually or with post registration external scripts. Upvoted!

I came across same issue, however interface automation during auto-registration can be achieved through ansible zabbix module. We have successfully implemented in our environments.

I believe it has been implemented under https://support.zabbix.com/browse/ZBXNEXT-2072 in Zabbix 5.2.

Sorry, didn't notice that it is about auto-discovery, re-opened.
