The ceilometer.volume.cinder Module¶

Common code for working with volumes

class ceilometer.volume.cinder.VolumeBackupSize(conf)[source]¶

Bases: ceilometer.volume.cinder._Base

FIELDS = ['name', 'object_count', 'container', 'volume_id', 'status', 'description']¶

default_discovery¶

get_samples(manager, cache, resources)[source]¶

Return a sequence of Counter instances from polling the resources.

Parameters:

manager – The service manager class invoking the plugin. cache – A dictionary to allow pollsters to pass data between themselves when recomputing it would be expensive (e.g., asking another service for a list of objects). resources – A list of resources the pollster will get data from. It’s up to the specific pollster to decide how to use it. It is usually supplied by a discovery, see default_discovery for more information.

class ceilometer.volume.cinder.VolumeSizePollster(conf)[source]¶

Bases: ceilometer.volume.cinder._Base

FIELDS = ['name', 'status', 'volume_type', 'os-vol-host-attr:host', 'migration_status', 'attachments', 'snapshot_id', 'source_volid']¶

default_discovery¶
