-Gnocchi Plugin Guide for OSM MON
-********************************
-The Gnocchi plugin for the MON module allows an OSM user to utilise metric and
-resource functionality from their OpenStack deployment.
-
-This plugin allows you to create, list, delete and read metric data.
-
- .. note::
-
-
- An update metric request can also be performed but Gnocchi does not
- support this functionality, your request will just be logged.
-
-Supported Metrics
------------------
-Currently this plugin only supports the following metrics:
-
-* AVERAGE_MEMORY_UTILIZATION
-* DISK_READ_OPS
-* DISK_WRITE_OPS
-* DISK_READ_BYTES
-* DISK_WRITE_BYTES
-* PACKETS_DROPPED
-* PACKETS_RECEIVED
-* PACKETS_SENT
-* CPU_UTILIZATION
-
-Configuring a Metric
---------------------
-Any of the above OpenStack metrics can be configured based on the following
-configuration options:
-
-* Resource_uuid: Specifies the resource that your metric will be configured for.
-* Metric_name: Specify one of the above metrics for your desired resource.
-* Metric_unit: the unit that you wish your metric to be monitored in.
-
- .. note::
-
-
- Your metric can only be specified once for a particular resource.
-
-Deleting a Metric
------------------
-To delete a metric all that is required is to specify the metric_uuid of the
-metric you wish to delete.
-
-Listing Metrics
----------------
-A full list of OSM generated metrics can be created by perform a list request
-without defining any list parameters.
-
-Specific lists can also be created based on two different input parameters:
-
-* Metric_name
-* Resource_uuid
-
-These parameters will generate a list of metrics that have the metric_name
-and/or the resource_uuid defined. These parameters can be defined seperately or
-in combination.
-
-Reading Metric Data
--------------------
-To define what metric data you want to read from the Gnocchi database a no. of
-parameters have to be defined:
-
-* Metric_uuid: To define which metric's data you would like to read.
-* Collection_unit: Defines the unit of time that you want to read the metric
- data over.
-
- .. note::
-
-
- The units that you can define include: HR, DAY, WEEK, MONTH, YEAR.
-
-* Collection_period: defines the integer value of the collection period.
- E.g. 1 DAY.
-
-This type of request results in a list of data values and a corresponding list
-of timestamps.
