Description Graeme Gillies 2016-01-22 04:55:43 UTC

When using horizon on a moderately loaded RHOS 7.0.3 installation, if you browse to the url

http://openstack.example.com/dashboard/admin/metering/

the page sits there taking forever to load, eventually timing out with a 504 error.

This 504 error is coming from haproxy which has a hard limit set to time out pages that take longer than 1 minute to load.

The underlying issue looks like this page and the way it interacts with ceilometer is simply sub par.

Unfortunately, this is a well known issue; see https://julien.danjou.info/blog/2014/openstack-ceilometer-the-gnocchi-experiment

The only recommendation I can currently give is to disable the metering panel:

[root@euler enabled(keystone_admin)]# pwd
/usr/share/openstack-dashboard/openstack_dashboard/local/enabled

[root@euler enabled(keystone_admin)]# cat _99_disable_metering_panel.py
# The slug of the panel to be added to HORIZON_CONFIG. Required.
PANEL = 'metering'
# The slug of the dashboard the PANEL associated with. Required.
PANEL_DASHBOARD = 'admin'
# The slug of the panel group the PANEL is associated with.
PANEL_GROUP = 'admin'

REMOVE_PANEL = True


That's not a real fix; on the long term, horizon should stop using ceilometer and should switch to gnocchi.

Unfortunately, there not really anything we can do to fix this. Ceilometer is the wrong tool for this kind of task. Upstream will remove metering via ceilometer in horizon.
