The ceilometer.storage.impl_log Module

Simple logging storage backend.

class ceilometer.storage.impl_log.Connection(url)

Bases: ceilometer.storage.base.Connection

Log the data.

clear()

clear_expired_metering_data(ttl)

Clear expired data from the backend storage system.

Clearing occurs according to the time-to-live. :param ttl: Number of seconds to keep records for.

get_meter_statistics(sample_filter, period=None, groupby=None, aggregate=None)

Return a dictionary containing meter statistics.

Meter statistics is described by the query parameters. The filter must have a meter value set.

{ ‘min’:

‘max’: ‘avg’: ‘sum’: ‘count’: ‘period’: ‘period_start’: ‘period_end’: ‘duration’: ‘duration_start’: ‘duration_end’: }

get_meters(user=None, project=None, resource=None, source=None, limit=None, metaquery=None, unique=False)

Return an iterable of dictionaries containing meter information.

{ ‘name’: name of the meter,

‘type’: type of the meter (gauge, delta, cumulative), ‘resource_id’: UUID of the resource, ‘project_id’: UUID of project owning the resource, ‘user_id’: UUID of user owning the resource, }

Parameters:

• user – Optional ID for user that owns the resource.
• project – Optional ID for project that owns the resource.
• resource – Optional resource filter.
• source – Optional source filter.
• limit – Maximum number of results to return.
• metaquery – Optional dict with metadata to match on.
• unique – If set to true, return only unique meter information.

get_resources(user=None, project=None, source=None, start_timestamp=None, start_timestamp_op=None, end_timestamp=None, end_timestamp_op=None, metaquery=None, resource=None, limit=None)

Return an iterable of dictionaries containing resource information.

{ ‘resource_id’: UUID of the resource,

‘project_id’: UUID of project owning the resource, ‘user_id’: UUID of user owning the resource, ‘timestamp’: UTC datetime of last update to the resource, ‘metadata’: most current metadata for the resource, ‘meter’: list of the meters reporting data for the resource, }

Parameters:

• user – Optional ID for user that owns the resource.
• project – Optional ID for project that owns the resource.
• source – Optional source filter.
• start_timestamp – Optional modified timestamp start range.
• start_timestamp_op – Optional start time operator, like gt, ge.
• end_timestamp – Optional modified timestamp end range.
• end_timestamp_op – Optional end time operator, like lt, le.
• metaquery – Optional dict with metadata to match on.
• resource – Optional resource filter.
• limit – Maximum number of results to return.

get_samples(sample_filter, limit=None)

Return an iterable of samples.

Items are created by ceilometer.meter.meter_message_from_counter().

record_metering_data(data)

Write the data to the backend storage system.

Parameters:data – a dictionary such as returned by ceilometer.meter.meter_message_from_counter.
