thanks for the pointers Sam.I took a quick look. I agree that the VM Heartbeat / Health-check looks like a good fit into Masakari. Currently your instance monitoring looks like it is strictly black-box type monitoring thru libvirt events. Is that correct ? i.e. you do not do any intrusive type monitoring of the instance thru the QUEMU Guest Agent facility correct ?
That is correct: https://github.com/openstack/masakari-monitors/blob/master/masakarimonitors/instancemonitor/instance.py
I think this is what VM Heartbeat / Health-check would add to Masaraki. Let me know if you agree.
OK, so you are looking for something slightly different I guess, based on this QEMU guest agent? https://wiki.libvirt.org/page/Qemu_guest_agent That would require the agent to be installed in the images, which is extra work but I imagine quite easily justifiable in some scenarios. What failure modes do you have in mind for covering with this approach - things like the guest kernel freezing, for instance? __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
