Hi all,


Juste tried to implement a single Linux Host with the CMA agent configured on my poller (Centreon 24.10.12)
I chose the default mode : "The Agents connects to the Poller".


Everything is working well, but I am suprised to see that:

- All the services are by in Passive Mode (→ not possible to force check)
- If the centagent service (On the monitored host) fails to start or stops for any reason : All the services will remain OK status … so no alert … which means that the host is not rmonitored any more.  (This is inherent to the PASSIVE MODE)
​​​​​​​- Another consequence is that (with passive service) you cannot see the real Command executed by the probe by clicking on it  (As we have with Active probes).

I was expecting that the agent would initiate the connection to the poller while starting only… and that then: the probes executions would be initiated by the poller (as active services).

Is there any improvement planned or that or is it wanted to be working like that ?

I was told that services are also all passive with the other mode : "The Poller connects to the Agent".
(I didn’t try it again)

Thanks a lot,

Kind Regards.

Hi,

Thanks for your feedbacks.

- All the services are by in Passive Mode (→ not possible to force check)
Yes, in order to match with observability/opentelemetry philosophy, CMA run in passive mode.

It allow, for example, to handle huge volumetry, by reducing poller workload.

We will bring forcecheck in 25.10.0

 

- If the centagent service (On the monitored host) fails to start or stops for any reason : All the services will remain OK status … so no alert … which means that the host is not rmonitored any more.  (This is inherent to the PASSIVE MODE)


We will bring freshness management (with existing configuration fields) and retries in next minor 25.10.x (.1 or .2)

 

- Another consequence is that (with passive service) you cannot see the real Command executed by the probe by clicking on it  (As we have with Active probes).


You can, in resource status, but only for Linux Hosts, since there is a bug linked to Windows commands. We will fix it in next minor 25.10.x (.1 or .2)

 

I was told that services are also all passive with the other mode : "The Poller connects to the Agent".

Yes, the direction only impact initial connection. Once connection is establshed, communication is the same (bidirectional, and passive mode).
 

Hope it helps
