Okay got it. Thanks for the clarification.

Hi Achim,

it's not a Decanter issue but a Karaf instance warning.

Let me explain.

Decanter JMX collector retrieves all MBeans in the MBean server and get all attributes on the MBeans.

Especially, it gets the Karaf InstanceMBean, and it gets the "instances" attribute (returning a tabular data of all Karaf instances, including the root instance).

When we call "instances" attribute (even using jconsole or any JMX client), the InstanceMBean connects using ssh on the instances to get their current status (started or not).

So, the warning you are seeing is actually the log when the Decanter JMX collector call the "instances" attribute on the InstanceMBean.

To avoid this, you can:
- if you don't care about this MBean, you can exclude the InstanceMBean object name in the Decanter JMX collector configuration
- just turn OFF (or use WARN) for the logger (in etc/org.ops4j.pax.logging.cfg, you just add log4j.logger.org.apache.sshd.core=WARN)

Regards
JB

Are there any updates on this? I have the same issue on Windows running
Decanter 1.1.0 on Karaf 4.0.5.

I did run the following statements

feature repo:add decanter 1.1.0
feature:install decanter-collector-jmx

I already tryed to change the url from local to service:jmx:rmi... but
the warning still occurs.

Thanks

    This is running on my Windows XP laptop in sort of a test mode. I am
    running 4.0.4 though.  This issue didn’t exist until I installed
    Decanter for whatever reason.  I guess I could just uninstall
    everything that came with Decanter and see if the problem goes
    away.  I’ll hold off on that for a bit and see if anybody else has
    thoughts.____

    Scott,

    I just tested on a fresh Karaf 4.0.4 and I'm not having any errors.

    i.e.:

    - Maybe a firewall blocking it or something?
    - I'm on linux, you're maybe on another OS?

    I'm not experienced enough with sshd, if the 2 above are not a
    problem or the same as me. We will need to wait for someone else :)

        Scott,

        Can you tell us what features you exactly installed? (or
        commands you executed)
        Since "Decanter / ElasticSearch / Kibana" is a little vague..

                Can you tell us which version of decanter is installed?
                In case of 3.0 snapshot, that is a rather old version
                and is not the latest, as we decided to detach the
                decanter versioning from the karaf base versioning. ____

                In that case make sure you have the latest released
