Hello, im using Opennebula latest version for my vmware cluster (22 hosts - 12 datastores), active and monitored in opennebula is just 30 vm. From some weeks my opennebula server going to high load, i checked /var/log/one/oned.log and no errors but the vm status became UNKNOWN. I had done some tests and discovered that after restart opennebula the load is low… after 10/15 minutes the first 100 is at 100% and so on for all the server cpus, so for me the only solution is just restart opennebula. I suppose that ruby is getting all the server resources infact after 1 hour i can see serval processes as this: /bin/bash /var/lib/one/remotes/im/run\_probes vcenter /var/lib/one//datastores 4124 20 4 Cluster I attached the HTOP resut… What’s wrong with my opennebula installation ?

It seems that monitoring takes more that 60 seconds to finish, the default monitoring interval. This causes new monitoring processes to start before the previous one finished. - Stop OpenNebula - Clean the host of run probes / ruby processes - Time the execution of the monitoring agent (as oneadmin): ```auto $ time /bin/bash /var/lib/one/remotes/im/run_probes vcenter /var/lib/one//datastores 4124 20 4 Cluster ``` - Change the monitoring interval to a higher value that the time you got in the last step > ---
