Hi Jay,
Thanks for your comment. You suggestion is good but I am wondering why we cannot use or leverage Ceilometer to monitor infrastructure-related, as it can used to monitor tenant-related things.

I would not use Ceilometer for this, as it is more tenant-facing than infrastructure service facing. Instead, I would use a tried-and-true solution like Nagios and NRPE checks. Here's an example of such a check for a keystone endpoint: https://github.com/ghantoos/debian-nagios-plugins-openstack/blob/master/plugins/check_keystone Best, -jay From: Duan, Li-Gong (Gary@HPServers-Core-OE-PSC) Sent: Tuesday, July 29, 2014 5:05 PM To: openstack-dev@lists.openstack.org Subject: [Ceilometer] Generate Event or Notification in Ceilometer Hi Folks, Are there any guide or examples to show how to produce a new event or notification add add a handler for this event in ceilometer? I am asked to implement OpenStack service monitoring which will send an event and trigger the handler once a service, say nova-compute, crashes, in a short time. :( The link (http://docs.openstack.org/developer/ceilometer/events.html) does a good job on the explanation of concept and hence I know that I need to emit notification to message queue and ceilometer-collector will process them and generate events but it is far from real implementations.
