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. L
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.
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:
