Description Sasha Smolyak 2017-08-21 07:42:55 UTC
Description of problem:
Ceilometer can't find nova instance because of name differences: it appears as compute-2 for ceilometer in ceilometer.conf (host = socket.gethostname()) and as 
host=compute-2.localdomain in nova.conf.
So there are no events sent from that instance.

There are several ways of workaround, from removing host= in
nova.conf to adding it to ceilometer.conf.It should work by default so there should not be any need to add or remove host.

You can add Ceilometer DFG to this bug

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. Deploy puddle 2017-18-18.2
2. Create an instance
3. Observe the instance hostname

Actual results:
The names differ, no resource is found by ceilometer

Expected results:
The ceilometer must find the resource automatically

Additional info:

Comment 1 Sven Anderson 2017-08-25 15:01:57 UTC
If I'm not mistaken the nova.conf is correct, and the ceilometer.conf is wrong. So, I will move it to the Telemetry DFG for now.

Comment 2 Julien Danjou 2017-09-16 12:23:41 UTC
This is only a problem for deployment where hosts do not have fully qualified hostname, e.g. they rely on localdomain.
