Eoghan Glynn 2013-12-10 14:08:16 UTC Doc Text Cause: a slow leak of exchanges is experienced with the original topology used by the QPID driver for the openstack AMQP layer.

Consequence: the number of orphaned direct exchanges reported by QPID grows monotonically over time.

Fix: the v2 topology was introduced specifically to address this issue but must be selected explicitly in configuration, which in this case occurs in the distribution configuration for Ceilometer.

Result: the prior leakage of exchanges is no longer observed.

Fix: the v2 topology was introduced specifically to address this issue but must be selected explicitly in configuration, which in this case occurs in the distribution configuration for Ceilometer.

Result: the prior leakage of exchanges is no longer observed. 		The QPID driver's v2 topology was introduced to specifically address the slow growth of orphaned direct exchanges over time. By default, however, services still use the original v1 topology of the QPID driver; the v2 topology has to be explicitly configured via the 'qpid_topology_version = 2' parameter.

With this fix, the Metering service's distribution configuration file (/usr/share/ceilometer/ceilometer-dist.conf) now contains this parameter. This effectively sets the QPID driver's v2 topology as the default.
