boto.ec2.cloudwatch
===================

This module provides an interface to the Elastic Compute Cloud (EC2)
CloudWatch service from AWS.

class class boto.ec2.cloudwatch.CloudWatchConnection(aws_access_key_id=None, aws_secret_access_key=None, is_secure=True, port=None, proxy=None, proxy_port=None, proxy_user=None, proxy_pass=None, debug=0, https_connection_factory=None, region=None, path='/', security_token=None, validate_certs=True)

   Init method to create a new connection to EC2 Monitoring Service.

   B{Note:} The host argument is overridden by the host specified in
   the boto configuration file.

   DefaultRegionEndpoint = 'monitoring.us-east-1.amazonaws.com'

   DefaultRegionName = 'us-east-1'

   build_list_params(params, items, label)

   build_put_params(params, name, value=None, timestamp=None, unit=None, dimensions=None, statistics=None)

   create_alarm(alarm)

      Creates or updates an alarm and associates it with the specified
      Amazon CloudWatch metric. Optionally, this operation can
      associate one or more Amazon Simple Notification Service
      resources with the alarm.

      When this operation creates an alarm, the alarm state is
      immediately set to INSUFFICIENT_DATA. The alarm is evaluated and
      its StateValue is set appropriately. Any actions associated with
      the StateValue is then executed.

      When updating an existing alarm, its StateValue is left
      unchanged.

      Parameters:
         **alarm** (*boto.ec2.cloudwatch.alarm.MetricAlarm*) --
         MetricAlarm object.

   delete_alarms(alarms)

      Deletes all specified alarms. In the event of an error, no
      alarms are deleted.

      Parameters:
         **alarms** (*list*) -- List of alarm names.

   describe_alarm_history(alarm_name=None, start_date=None, end_date=None, max_records=None, history_item_type=None, next_token=None)

      Retrieves history for the specified alarm. Filter alarms by date
      range or item type. If an alarm name is not specified, Amazon
      CloudWatch returns histories for all of the owner's alarms.

      Amazon CloudWatch retains the history of deleted alarms for a
      period of six weeks. If an alarm has been deleted, its history
      can still be queried.

      Parameters:
         * **alarm_name** (*string*) -- The name of the alarm.

         * **start_date** (*datetime*) -- The starting date to
           retrieve alarm history.

         * **end_date** (*datetime*) -- The starting date to retrieve
           alarm history.

         * **history_item_type** (*string*) -- The type of alarm
           histories to retreive (ConfigurationUpdate | StateUpdate |
           Action)

         * **max_records** (*int*) -- The maximum number of alarm
           descriptions to retrieve.

         * **next_token** (*string*) -- The token returned by a
           previous call to indicate that there is more data.

      :rtype list

   describe_alarms(action_prefix=None, alarm_name_prefix=None, alarm_names=None, max_records=None, state_value=None, next_token=None)

      Retrieves alarms with the specified names. If no name is
      specified, all alarms for the user are returned. Alarms can be
      retrieved by using only a prefix for the alarm name, the alarm
      state, or a prefix for any action.

      Parameters:
         * **action_name** -- The action name prefix.

         * **alarm_name_prefix** (*string*) -- The alarm name prefix.
           AlarmNames cannot be specified if this parameter is
           specified.

         * **alarm_names** (*list*) -- A list of alarm names to
           retrieve information for.

         * **max_records** (*int*) -- The maximum number of alarm
           descriptions to retrieve.

         * **state_value** (*string*) -- The state value to be used in
           matching alarms.

         * **next_token** (*string*) -- The token returned by a
           previous call to indicate that there is more data.

      :rtype list

         * **dimension_filters** -- A dictionary containing name/value
           pairs that will be used to filter the results.  The key in

   put_metric_alarm(alarm)

      Creates or updates an alarm and associates it with the specified
      Amazon CloudWatch metric. Optionally, this operation can
      associate one or more Amazon Simple Notification Service
      resources with the alarm.

      When this operation creates an alarm, the alarm state is
      immediately set to INSUFFICIENT_DATA. The alarm is evaluated and
      its StateValue is set appropriately. Any actions associated with
      the StateValue is then executed.

         MetricAlarm object.

   put_metric_data(namespace, name, value=None, timestamp=None, unit=None, dimensions=None, statistics=None)

      Publishes metric data points to Amazon CloudWatch. Amazon
      Cloudwatch associates the data points with the specified metric.
      If the specified metric does not exist, Amazon CloudWatch
      creates the metric. If a list is specified for some, but not
      all, of the arguments, the remaining arguments are repeated a
      corresponding number of times.

      Parameters:
         * **namespace** (*str*) -- The namespace of the metric.

         * **name** (*str or list*) -- The name of the metric.

         * **value** (*float or list*) -- The value for the metric.

         * **timestamp** (*datetime or list*) -- The time stamp used
           for the metric. If not specified, the default value is set
           to the time the metric data was received.

         * **unit** (*string or list*) -- The unit of the metric.
           Valid Values: Seconds | Microseconds | Milliseconds | Bytes
           | Kilobytes | Megabytes | Gigabytes | Terabytes | Bits |
           Kilobits | Megabits | Gigabits | Terabits | Percent | Count
           | Bytes/Second | Kilobytes/Second | Megabytes/Second |
           Gigabytes/Second | Terabytes/Second | Bits/Second |
           Kilobits/Second | Megabits/Second | Gigabits/Second |
           Terabits/Second | Count/Second | None

         * **dimensions** (*dict*) -- Add extra name value pairs to
           associate with the metric, i.e.: {'name1': value1, 'name2':
           (value2, value3)}

         * **statistics** (*dict or list*) --

           Use a statistic set instead of a value, for example:

              {'maximum': 30, 'minimum': 1, 'samplecount': 100, 'sum': 10000}

   set_alarm_state(alarm_name, state_reason, state_value, state_reason_data=None)

      Temporarily sets the state of an alarm. When the updated
      StateValue differs from the previous value, the action
      configured for the appropriate state is invoked. This is not a
      permanent change. The next periodic alarm check (in about a
      minute) will set the alarm to its actual state.

      Parameters:
         * **alarm_name** (*string*) -- Descriptive name for alarm.

         * **state_reason** (*string*) -- Human readable reason.

         * **state_value** (*string*) -- OK | ALARM |
           INSUFFICIENT_DATA

         * **state_reason_data** (*string*) -- Reason string (will be
           jsonified).

   update_alarm(alarm)

      Creates or updates an alarm and associates it with the specified
      Amazon CloudWatch metric. Optionally, this operation can
      associate one or more Amazon Simple Notification Service
      resources with the alarm.

      When this operation creates an alarm, the alarm state is
      immediately set to INSUFFICIENT_DATA. The alarm is evaluated and
      its StateValue is set appropriately. Any actions associated with
      the StateValue is then executed.

      When updating an existing alarm, its StateValue is left
      unchanged.
