Unsecure install of Centreon Monitoring Agent

Hi, 

Thanks for your interest in Centreon Monitoring Agent

No TLS option is provided in 24.10.8 (web) / 24.10.7 (collect) version of Centreon.

So you may need an update.

You will find No TLS documentation in this section : https://docs.centreon.com/pp/integrations/plugin-packs/getting-started/how-to-guides/cma/#testing-mode-unencrypted-communication

Telle me if you need more detail on this.

The certificates in Poller/agent configuration are mandatory only if you select “TLS” option.

Otherwise, they are not present (as said, this option is only available in 24.10.8 webapp)

Thanks for your reply!

It seems to work with my host when the agent initiates the connection with the poller (passive mode). I would like to switch to active mode. According to the manual, the checks are OK, but I can’t acknowledge the alerts, so I deduce that the host is still in passive mode.

Second question: in production, we will have around 500 hosts (on 20 pollers). Is there a way to bulk select hosts in the poller/agent configuration (under the "host configurations" step)?

Hi,

you are welcome !

What’s exactly the problem/error message on acknowledgements ? It should work in both modes.

There is no active mode for now in Centreon Monitoring Agent, the two connection mode are only for the connection initialization. Once the connection is established, the communication is done the same way on both modes, but remains passive. You can check the schema here : https://docs.centreon.com/pp/integrations/plugin-packs/getting-started/how-to-guides/cma/#how-do-the-host-and-the-poller-interact, you will see that only the first arrow (initiate) changes.

For 500 hosts on 20 pollers, i suggest to use API in order to popule Agent configuration.

Let me know if you need API examples.

Thank you Florian !

If it’s possible, I would like some examples ;-)

Here is an example (we will improve the API documentation on this) : 

Tell me if you need more help on this, and we will plan a meet.

{
	"type": "centreon-agent",
	"name": "my-agent-conf",
	"connection_mode": "secure",
	"poller_ids": [
		5
	],
	"configuration": {
		"is_reverse": true,
		"otel_public_certificate": "poller_certif.crt",
		"otel_private_key": "poller_key.key"}
        ],
		"hosts": [
			{
				"address": "1.2.3.4",
				"port": 443,
				"poller_ca_certificate": "poller_certif.crt",
		        "poller_ca_name": "poller_name"}
			}
		]
	}
}

Why not for a meet, if possible.  Thanks Florian!

How can we organise ourselves ?

I sent you a private message

Done! Thanks
