[one-users] Monitoring issue right after host creation [No Monitoring Information | OpenNebula 3.2.0]

[biro lehel]

Hello Ruben,

as I mentioned at the bottom of my previous email, I already run /var/tmp/one/im/run_probes with the necessary parameters on pcls (my only host), which resulted in the same (empty) output. The file exists, it just doesn't produce the expected (or any) output, and I couldn't find the reason so far.

I didn't try 'onehost sync', but I could try tomorrow morning (since I got home already, and I'm not at the respective computers), if you consider that it might help.

Any other suggestions?

Cheers,
Lehel.

Hi,
Could you please check the contents of  /var/tmp/one/im/ at pcls? It seems that there are no probes there. If that's the case you can copy them by hand or use onehost sync and wait for a monitoring action on the host.


Cheers
Ruben

Hello,

I tried to add my one and only host, by executing on the front-end:



> onehost create pcls im_kvm vmm_kvm tm_shared dummy

Issuing the 'onehost list' command, the result seems to be the one expected. However, issuing 'onehost show pcls' command results in zero values and NO monitoring information:



oneadmin at linux-4dsu:~/remotes/im> onehost show pcls

MONITORING INFORMATION   

(the report ends here, without monitoring information).

I had some errors before, oned.log having:



Thu Mar  8 15:49:03 2012 [InM][I]: Command execution fail: 'if [ -x "/var/tmp/one/im/run_probes" ]; then /var/tmp/one/im/run_probes kvm 4 pcls; else                              exit 42; fi'
Thu Mar  8 15:49:03 2012 [InM][I]: ExitCode: 42


Thu Mar  8 15:49:03 2012 [InM][E]: Error monitoring host 4 : MONITOR FAILURE 4 -

However, I
 fixed this by simply adding execution permission to the run_probes file mentioned above (since, it didn't have one). At this moment, oned.log contains no errors (to be precise, it says,

Thu Mar  8 17:16:12 2012 [ReM][D]: HostPoolInfo method invoked


Thu Mar  8 17:16:12 2012 [ReM][D]: VirtualMachinePoolInfo method invoked
Thu Mar  8 17:16:12 2012 [ReM][D]: AclInfo method invoked
Thu Mar  8 17:16:13 2012 [InM][I]: Monitoring host pcls (6)
Thu Mar  8 17:16:18 2012 [InM][I]: ExitCode: 0


Thu Mar  8 17:16:18 2012 [InM][D]: Host 6 successfully monitored.
Thu Mar  8 17:16:19 2012 [ReM][D]: UserPoolInfo method invoked
Thu Mar  8 17:16:19 2012 [AuM][D]: Message received: LOG I 874 ExitCode: 0

).



Firing the respective command on the host (  /var/tmp/one/im/run_probes kvm 4 pcls ) also results in no output and no errors (it simply puts a space on a new line in the CLI).

I don't
 think that this is the expected behavior and I think that there is a problem somewhere. What am I missing? Any suggestions?

Thanks,
Lehel.
