Hi, If you don't want to install any agents like snmpd or nrpe and plugins on your hosts, you can monitor some basic metrics like cpu, memory, status, nics,... of your hosts with check_rhev3, as Dominique already mentioned. See the documentation about what's possible at the moment: https://github.com/ovido/check_rhev3/wiki/Usage-Documentation If you're missing something, this plugin doesn't provide yet (but is possible to fetch using oVirt's REST-API), please let me know and I'll update the plugin.

I think it depends all on what you do want to monitor.  a simple PING check is the least you should do, but this often is not enough. You can check the management modules of your hosts for hardware issues (iDRAC, ILO, IMM, ...) via nagios. In Addition to that, you can install a nagios (NRPE) client on your hypervisor, if you are running CentOS/RHEL/Fedora and perform some checks via this client. In addition to that, we do have check_rhev3 (https://github.com/ovid o/check_rhev3) running against our engine hosts to monitor various elements like status of host/cluster/network etc of our oVirt infrastructure. best,  Dominique -----Original Message----- From: Massimo Mad <mad1969it(a)gmail.com&gt; To: users(a)ovirt.org <users(a)ovirt.org&gt; Subject: [ovirt-users] Monitor with nagios Date: Fri, 29 Jan 2016 12:54:47 +0100 i want to monitor my infrastructure with 4 host bare-metal, but on the host there is not the snmp service installed.
