For operators, I got the feeling that existing solutions fit well: - Traditional monitoring tools (Nagios, Zabbix, ....) are necessary anyway for infrastructure monitoring (CPU, RAM, disks, operating system, RabbitMQ, databases and more) and diagnostic purposes. Adding OpenStack service checks is fairly easy if you already have the toolchain. Is it really so easy? Rabbitmq has an "aliveness" test that is easy to hook into. I don't know exactly what it does, other than what the doc says, but I should not have to. If I want my standard monitoring system to call into a cloud and ask "is nova healthy?", "is glance healthy?", etc. are their such calls? David, I think a healthchecking API per service is a fantastic idea. I would like to see the same thing in OpenStack services. The real way to check health of nova for example, is for Nova to do the job of checking it’s own health. It knows its internals best and can do the job. Maybe this project can introduce API calls and implementations into the major services to do such work. Regards -steve There are various sets of calls associated with nagios, zabbix, etc. but those seem like "after-market" parts for a car. Seems to me the services themselves would know best how to check if they are healthy, particularly as that could change version to version. Has their been discussion of adding a health-check (admin) api in each service? Lacking that, is there documentation from any OpenStack projects about "how to check the health of nova"? When I saw this thread start, that is what I thought it was going to be about. -David - OpenStack projects like Rally or Tempest can generate synthetic loads and run end-to-end tests. Integrating them with a monitoring system isn't terribly difficult either. As far as Monitoring-as-a-service is concerned, do you have plans to integrate/leverage Ceilometer?

CloudPulse provides Openstack health-checking services to both operators, tenants, and applications. This project will begin as a StackForge project based upon an empty cookiecutter[1] repo. The repos to work in are: Server: https://github.com/stackforge/cloudpulse Client: https://github.com/stackforge/python-cloudpulseclient Please join us via iRC on #openstack-cloudpulse on freenode. I am holding a doodle poll to select times for our first meeting the week after summit. This doodle poll will close May 24th and meeting times will be announced on the mailing list at that time. At our first IRC meeting, we will draft additional core team members, so if your interested in joining a fresh new development effort, please attend our first meeting. Please take a moment if your interested in CloudPulse to fill out the doodle poll here: https://doodle.com/kcpvzy8kfrxe6rvb The initial core team is composed of Ajay Kalambur, Behzad Dastur, Ian Wells, Pradeep chandrasekhar, Steven Dake and Vinod Pandarinathan. I expect more members to join during our initial meeting. A little bit about CloudPulse: Cloud operators need notification of OpenStack failures before a customer reports the failure. Cloud operators can then take timely corrective actions with minimal disruption to applications. Many cloud applications, including those I am interested in (NFV) have very stringent service level agreements. Loss of service can trigger contractual costs associated with the service. Application high availability requires an operational OpenStack Cloud, and the reality is that occascionally OpenStack clouds fail in some mysterious ways. This project intends to identify when those failures occur so corrective actions may be taken by operators, tenants, and the applications themselves. OpenStack is considered healthy when OpenStack API services respond appropriately. Further OpenStack is healthy when network traffic can be sent between the tenant networks and can access the Internet. Finally OpenStack is healthy when all infrastructure cluster elements are in an operational state. For information about blueprints check out: https://blueprints.launchpad.net/cloudpulse https://blueprints.launchpad.net/python-cloudpulseclient For more details, check out our Wiki: https://wiki.openstack.org/wiki/Cloudpulse Plase join the CloudPulse team in designing and implementing a world-class Carrier Grade system for checking the health of OpenStack clouds. We look forward to seeing you on IRC on #openstack-cloudpulse.
