Hello,<div><br></div><div>I have recently installed OpenNebula 3.0 (from source) and noticed that the added hosts are not being monitored, they just remain in INIT state. In var/oned.log I see entries like these:</div><div>
<div>Thu Oct 6 08:01:51 2011 [InM][I]: Monitoring host zrhs69 (2)</div><div>Thu Oct 6 08:01:51 2011 [InM][I]: Monitoring host zrhs6a (3)</div><div>Thu Oct 6 08:02:06 2011 [ReM][D]: HostPoolInfo method invoked</div></div>
<div>oneadmin user is able to ssh into the hosts without a password.</div><div><br></div><div>After looking in etc/im_kvm folder I saw that it is empty. Is this normal? How are hosts being monitored in OpenNebula 3.0 ?</div>
<div><br></div><div>Can anyone give me a hint on how to proceed?</div><div><br></div><div>Best regards,</div><div>Florian</div><font color="#888888"><div><br></div>

<br></blockquote></div><br>Hello Florian,<div><br></div><div> In /etc/one/oned.conf at the " KVM Information Driver Manager Configuration " section:</div><div><div>IM_MAD = [</div><div> name = "im_kvm",</div>
<div> executable = "one_im_ssh",</div><div> arguments = "-r 0 -t 15 kvm" ]</div></div><div><br></div><div>The executable one_im_ssh is located in /usr/lib/one/mads or $ONE_LOCATION/lib/mads, depends if you installed OpenNebula self contained on in root (/). </div>
<div>The one_im_ssh script sets $MAD_LOCATION and executes $MAD_LOCATION/one_im_exec $*. Maybe you can find out what happens following the logic found in those scripts.</div><div><br></div><div>The monitoring part works for me. I have ONE3.0 on Debian Squeeze (6.0.2) as frontend. The nodes are also Debian 6.0.2 with qemu-kvm 0.12.5 and libvirt 0.8.3-5.</div>
