newrelic_api.application_instances¶

class newrelic_api.application_instances.ApplicationInstances(api_key=None)¶

An interface for interacting with the New Relic Application Instances API.

__init__(api_key=None)¶

Parameters:	api_key (str) – The API key. If no key is passed, the environment variable NEW_RELIC_API_KEY is used.
Raises:	If the api_key parameter is not present, and no environment variable is present, a newrelic_api.exceptions.ConfigurationException is raised.

list(application_id, filter_hostname=None, filter_ids=None, page=None)¶

This API endpoint returns a paginated list of instances associated with the given application.

Application instances can be filtered by hostname, or the list of application instance IDs.

Parameters:	application_id (int) – Application ID filter_hostname (str) – Filter by server hostname filter_ids (list of ints) – Filter by application instance ids page (int) – Pagination index
Return type:	dict
Returns:	The JSON response of the API, with an additional ‘pages’ key if there are paginated results

metric_data(application_id, instance_id, names, values=None, from_dt=None, to_dt=None, summarize=False)¶

This API endpoint returns a list of values for each of the requested metrics. The list of available metrics can be returned using the Metric Name API endpoint. Metric data can be filtered by a number of parameters, including multiple names and values, and by time range. Metric names and values will be matched intelligently in the background. You can also retrieve a summarized data point across the entire time range selected by using the summarize parameter.

Note All times sent and received are formatted in UTC. The default time range is the last 30 minutes.

Parameters:	application_id (int) – Application ID instance_id (int) – Application Host ID names (list of str) – Retrieve specific metrics by name values (list of str) – Retrieve specific metric values from_dt (datetime) – Retrieve metrics after this time to_dt (datetime) – Retrieve metrics before this time summarize (bool) – Summarize the data
Return type:	dict
Returns:	The JSON response of the API

    "metric_data": {
        "from": "time",
        "to": "time",

                ]
            }
        ]
    }
}

metric_names(application_id, instance_id, name=None, page=None)¶

Return a list of known metrics and their value names for the given resource.

Parameters:	application_id (int) – Application ID instance_id (int) – Application Host ID name (str) – Filter metrics by name page (int) – Pagination index
