Open Stack

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.



Regards,

Gary

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:

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.

Regards,
Gary
