Horizon resource usage showing just glance meters

This document (7022318) is provided subject to the disclaimer at the end of this document.

Environment

SUSE OpenStack Cloud 6

Situation

In Resource Usage tab in Horizon only Image (glance service) meters are retrieved.  CPU, RAM, network and disk usage details are not displayed.

Resolution

Manually increase the "default_api_return_limit" ceilometer configuration option value by creating a custom /etc/ceilometer/ceilometer.conf.d/101-ceilometer-api.conf configuration file on each controller node with the following contents:

[api]

default_api_return_limit = 1000

Cause

The ceilometer admin dashboard in Horizon doesn't specify a limit for the number of entries returned by ceilometer API calls. Default_api_return_limit configuration option is used to limit the number of returned entries, which on certain systems may be too low.

Ceilometer CLI doesn't suffer from this limitation. Following command takes precedence over default_api_return_limit and can be used to verify whether ceilometer has the data available :

ceilometer meter-list -l 5000
