Re: [openstack-dev] [Ceilometer] Generate Event or Notification in Ceilometer
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.

You *could* use Ceilometer for this, sure. But I just don't recommend it. For performance reasons.

Re: [openstack-dev] [Ceilometer] Generate Event or Notification in Ceilometer
If all you want to do is publish a notification you can use oslo.messaging directly. Or, for something lighter weight, we have Notabene, which is a small wrapper on Kombu. An example of how our notification simulator/generator uses it is available here: https://github.com/StackTach/notigen/blob/master/bin/event_pump.py Of course, you'll have to ensure you fabricate a proper event payload. Hope it helps -S From: Duan, Li-Gong (Gary@HPServers-Core-OE-PSC) [li-gong.d...@hp.com] Sent: Tuesday, July 29, 2014 6:05 AM To: openstack-dev@lists.openstack.org Subject: [openstack-dev] [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?
