Bug Description

The following low-priority bug was fixed in Ceilometer Mitaka.
https://bugs.launchpad.net/ceilometer/+bug/1499403

However, in combination with Nagios and other monitoring tools we use in scope of LMA, this issue results in Ceilometer flapping on the monitoring dashboard and makes Ceilometer monitoring useless.
So, we need to backport this fix into the older MOS versions we are shipping with LMA.

Fix for resource polling warnings

When neutron services are disabled,
neutron client logs the 404 exception
at warn level, this exception log
is unwanted and it suffices to log
just the error message.

Test steps:

1. Create env with telemetry on controller
2. Go to controller and check log file /var/log/ceilometer/ceilometer-agent-central.log

Customer issue caused by multiline warning:

"2016-10-21 07:35:34.013 20951 WARNING ceilometer.neutron_client [-] 404 Not Found

The resource could not be found."

After patching that should be one line warning:

"2016-10-21 12:08:56.343 15005 WARNING ceilometer.neutron_client [-] The resource could not be found."

After updates:

The resource could not be found.

Move to Confirmed status.

In MOS7 and MOS8 neutron client has different behavior compared to MOS9. That is the reason that we have multiline warning on configurations without Neutron DVR. But with fully configured Neutron DVR there is no such problem as it was confirmed from customer side.

Bug fixed in MOS7 but result is not equal to https://bugs.launchpad.net/ceilometer/+bug/1499403
