Well, Nagios is being considered to be used or used by Gluster guys. However, it will still require (AFAIK) to code some nagios plugin to perfrom the health check. In addition, you will have to report somehow the state change to engine. IMHO, this a bit of an overkill (look also at the time that the check is run - once in an hour, so it can't be compared to getVmStats). > > > > > > > > > > ----- Original Message ----- > > > > > From: "Eli Mesika" <[email protected]> > > > > > To: "users" <[email protected]> > > > > > Cc: "Arthur Berezin" <[email protected]> > > > > > Sent: Sunday, May 4, 2014 12:18:47 PM > > > > > Subject: [ovirt-users] oVirt 3.5 : "Power Management Health Check" - > > > > > feature pages > > > > > > > > > > Hi > > > > > > > > > > The following wiki pages were added to the "Power Management Health > > > > > Check" > > > > > feature planned for oVirt 3.5 > > > > > > > > > > http://www.ovirt.org/Features/PMHealthCheck > > > > > http://www.ovirt.org/Features/Design/DetailedPMHealthCheck > > > > > > > > > > Your comments/questions are mostly welcomed. > > > > > > > > > > Thanks > > > > > Eli Mesika > > > > > _______________________________________________ > > > > > Users mailing list > > > > > [email protected] > > > > > http://lists.ovirt.org/mailman/listinfo/users > > > > > > > > > > > _______________________________________________ > > > Users mailing list > > > [email protected] > > > http://lists.ovirt.org/mailman/listinfo/users > > > > > > _______________________________________________ Users mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/users
