The API consists of six main resources:
1. Versions - Provides information about the supported Monasca API versions.
2. Metrics - The metric resource allows the storage and retrieval of metrics.
3. Measurements - Operations for accessing measurements of metrics.
4. Statistics - Operations for accessing statistics about metrics.
1. Versions - Provides information about the supported versions of the API.
2. Metrics - Provides for storage and retrieval of metrics.
3. Measurements - Operations for querying measurements of metrics.
4. Statistics - Operations for evaluating statistics of metrics.
5. Notification Methods - Represents a method, such as email, which can be associated with an alarm via an action. When an alarm is triggered notification methods associated with the alarm are triggered.
5. Alarms - Identifies one or more metrics scoped by name and dimensions, which should trigger a set of actions when the value of a threshold is exceeded.
5. Alarms - Provides CRUD operations for alarms and querying the alarm state history.
Before using the API, you must first get a valid auth token from Keystone. All API operations require an auth token specified in the header of the http request.
## Name and Dimensions
## Metric Name and Dimensions
A metric is uniquely identified by a name and set of dimensions.
### Name
Defines the name of a metric. A name is of type string(64).
### Dimensions
A dictionary of (key, value) pairs. The key and value are of type string(255). Dimensions may only use the characters from: a-z A-Z 0-9 . _ -.

# Common Responses
The Monasca API utilizes HTTP response codes to inform clients of the success or failure of each request. Clients should use the HTTP response code to trigger error handling if necessary (many errors can be resolved by retrying the request after a short delay). This section discusses various API error responses.
* 200 - A request succeeded.
* 201 - A resource has been successfully created.
* 204 - No content
* 400 -
* 400 - Bad request
* 401 - Unauthorized
* 404 - Not found
* 409 - Conflict
