The local resource caching mechanism may cause legacy resource info resided in the local cache and never be cleaned, uless the service being restarted. e.g. an instance has been migrated to another host, the instance info will reside in the cache on the ceilometer-polling service running on the old compute host.

|
|
A local cache is used when polling instance metrics to minimise calls Nova
|
|
API. A new option is added `resource_cache_expiry` to configure a time to
|
|
live for cache before it expires. This resolves issue where migrated
|
|
instances are not removed from cache. This is only relevant when
|
|
`instance_discovery_method` is set to `naive`. It is recommended to use
|
|
`libvirt_metadata` if possible.
