Re: [ovirt-users] oVirt 3.5 : "Power Management Health Check" - feature pages
Gilad, this is integral part of HA, For HA to work properly we rely on PM mechanism, this feature makes sure PM is available, ie. running existing "Check PM" periodically. We need to look at integrating a monitoring tool and it's benefits separately.

But it's an overkill for this RFE - run "PM Check" periodically, in addition to initial PM check at host setup stage.

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" > > > > > To: "users" > > > > > Cc: "Arthur Berezin" > > > > > 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 > > > > > Users@ovirt.org > > > > > http://lists.ovirt.org/mailman/listinfo/users > > > > > > > > > > > ___ > > > Users mailing list > > > Users@ovirt.org > > > http://lists.ovirt.org/mailman/listinfo/users > > > > > > ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

There are 2 major issues that we still don't cover: - No HA for monitoring, who checks the hosts when the engine is down. - No scale - the engine is a bottle-neck in network and compute. Although the above is a huge arch change, we need to start somewhere, this feature sounds like a candidate to introduce it. About the examples: http://sixrevisions.com/tools/10-free-server-network-monitoring-tools-that-kick-ass/ The main goal of the feature if my suggestion is taken, is to select to most appropriate one.

Hi, what 3rd party for example do you refer to?

Re: [ovirt-users] oVirt 3.5 : "Power Management Health Check" - feature pages
In this case engine periodically checks health of hosts' power management as HA relies on it.

Re: [ovirt-users] oVirt 3.5 : "Power Management Health Check" - feature pages
Hi Eli, Here is my comment :) Why engine needs to send the status health check, isn't there any 3rd parties that does it, that we can integrate with? If found, it probably has /less (known) bugs/more features/ and it's already written, tested, documented, allows further integration and probably deals with scale. btw, fixed some typos in your pages :-) Thanks, Gilad. - Original Message - > From: "Eli Mesika" > To: "users" > Cc: "Arthur Berezin" > 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 > Users@ovirt.org > http://lists.ovirt.org/mailman/listinfo/users > ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
