Description Takashi Kajinami 2021-01-15 06:03:41 UTC

Description of problem:

Currently the following meters are enabled by default when ManagePolling: true.

However disk.* meters were already removed from ceilometer[1], and
we don't have any valid disk performance meters enabled.

Because of this we don't get any disk performance captured by ceilometer,
unless we customize pollong.yaml


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


How reproducible:
Always

Steps to Reproduce:
1. Deploy overcloud with ceilometer enabled and ManagePolling: true
2. Create an instance

Actual results:
Any disk performance meters are not captured

Expected results:
Disk performance meters are captured
