[openstack-dev] [pacemaker] Live migration with VirtualDomain resource-agent
by Murali Annamneni 27 Nov '18

27 Nov '18

Hi, I'm trying to setup pacemaker for live-migration when a compute node hosting the VM goes down. So, I created cluster resource for the compute-instance (demo1) with 'VirtualDomain' resource agent. >>> pcs resource create demo1 VirtualDomain migrateuri="qemu+tcp://<DestinationCompuNode>:16509/system" config="/etc/pacemaker/demo1.xml" migration_transport="tcp" meta allow-migrate="true" op start timeout="120s" op stop timeout="180s" And I manually shutdown the compute node hosting the vm, but, I don't see the migration is happening. Can someone please help me what I am missing here ? Thanks & Regards, Murali __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: OpenStack-dev-request@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

Re: [OCTAVIA] How to monitor amphora
by Bedyk, Witold 27 Nov '18

Hi everyone, Monasca is the service which offers centralized monitoring and logging. As Joseph has written, you can probably use the monasca-agent and configure the existing system[1] and process[2] checks. If you need Octavia specific metrics, you can instrument your code using monasca-statsd library [3]. Best greetings Witek [1] https://github.com/openstack/monasca-agent/blob/master/docs/Plugins.md#syst… [2] https://github.com/openstack/monasca-agent/blob/master/docs/Plugins.md#proc… [3] https://github.com/openstack/monasca-statsd

Re: [OCTAVIA] How to monitor amphora
by Joseph Davis 27 Nov '18

Hello Sa Pham and others, Just to throw another option in to your discussion, the monasca-agent would also be able to monitor the cpu, memory, etc. on an amphora. Similar to how the Ceilometer agent -> Gnocchi publishing would work, you could then use Monasca services to track usage and set alarms. And Monasca handles storage in a time series database (Cassandra or InfluxDB). https://github.com/openstack/monasca-agent/blob/master/docs/Agent.md has some details, an you can always ask questions in #openstack-monasca. joseph Adam Harwell wrote: I would also note (though I'm guessing you've heard this from Michael already) that logging and metrics for internal amphora data (like Haproxy logs, agent logs, etc) is on our roadmap to officially expose via some mechanism. We discussed possible ways to do this at the last PTG, but we were just waiting on someone to have time to do a blueprint for review. If you'd like to help get support for this upstream, you're welcome (actually, highly encouraged!) to hop into our IRC channel #openstack-lbaas and we can even help you get started.
