The ceilometer.compute.pollsters.disk Module¶

class ceilometer.compute.pollsters.disk.AggregateDiskPollster(conf)[source]¶

Bases: ceilometer.compute.pollsters.GenericComputePollster

aggregate_method(result)[source]¶

static get_additional_metadata(instance, stats)[source]¶

get_samples(*args, **kwargs)[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.
