Get Measurement Types

To retrieve the Measurement Types that apply to a specific measurement without returning a large document, issue the following GET command with a value of PT5M for both the granularity and period. This returns a document with only one data point for each measurement.

Base URL: https://cloud.mongodb.com/api/public/v1.0

Resource

copy

GET /groups/{PROJECT-ID}/hosts/{HOST-ID}/measurements

Request Path Parameters

Name	Type	Description
PROJECT-ID	string	Unique identifier of the project that owns the host.
HOST-ID	string	Unique identifier of the host that serves the MongoDB process.

Request Query Parameters

Unique Query Parameters

This endpoint accepts the following query parameters to filter returned measurements:

Name	Type	Description
granularity Required	string	Duration in ISO 8601 notation that specifies the interval between measurement data points. Measurement granularity can be expressed as days, hours, minutes, seconds and milliseconds using the following notation: P (for period) followed by: D for days (if desired) T for time (after days) H for hours M for minutes S for seconds Example Notation Duration PT30S 30 seconds P1T12H 1 day, 12 hours PT0.5S 500 milliseconds
period	string	Duration in ISO 8601 notation that specifies how far back in the past to retrieve measurements. Example To request the last 36 hours, include this query parameter: period=P1DT12H.
start	string	Timestamp in ISO 8601 date and time format in UTC for the beginning of the period for which to retrieve measurements. If you specify start you must also specify end.
end	string	Timestamp in ISO 8601 date and time format in UTC for the end of the period for which to retrieve measurements. If you specify end you must also specify start.
m	string	Measurements to return. If m is not specified, all measurements are returned. To specify multiple values for m, you must repeat the m parameter. Example copy ../measurements?m=CONNECTIONS&m=OPCOUNTER_CMD&m=OPCOUNTER_QUERY You must specify measurements that are valid for the host. Cloud Manager returns an error if any specified measurements are invalid For available measurements, see Measurement Types.

Note

Each measurement request must include either the period query parameter or both the start and end query parameters.

Common Query Parameters

This endpoint also accepts the query parameters common to all endpoints that return a single response:

Name	Type	Description	Default
pageNum	integer	Page number (1-index based).	1
itemsPerPage	integer	Number of items to return per page, up to a maximum of 500.	100
pretty	boolean	Indicates whether the response body should be in a prettyprint format.	false
envelope	boolean	Indicates whether or not to wrap the response in an envelope. Some API clients cannot access the HTTP response headers or status code. To remediate this, set "envelope" : true in the query. For endpoints that return one result, response body includes: status HTTP response code envelope Expected response body For endpoints that return a list of results, the results object is an envelope. Cloud Manager adds the status field to the response body.	None

Request Body Parameters

This endpoint does not use HTTP request body parameters.

Response

Name	Type	Description
databaseName	string	Database to which the measurement applies. Populated for Get Database Measurements only.
end	string	Timestamp in ISO 8601 date and time format in UTC for the end of the period the returned measurements cover.
granularity	string	Duration in ISO 8601 notation that specifies the size of the interval that each data point covers. Example PT5M specifies a 5-minute granularity.
groupId	string	Unique identifier of the project that owns the host.
hostId	string	Unique identifier of the host to which the measurements pertain.
measurements	object array	Each object in this array represents a measurement and the data points for that measurement.
measurements.dataPoints	object array	Each object represents a single data point. If there is no data point available for a particular moment in time, this value is set to null.
measurements.dataPoints.timestamp	string	Timestamp in ISO 8601 date and time format in UTC for the beginning of the time interval this data point represents.
measurements.dataPoints.value	float	Value of this data point.
measurements.name	string	Name of the measurement. Accepted values are given in the Measurement Types page.
measurements.units	string	How this measurement is quantified. Accepted units are: PERCENT MILLISECONDS BYTES GIGABYTES BYTES_PER_SECOND MEGABYTES_PER_SECOND GIGABYTES_PER_HOUR SCALAR_PER_SECOND SCALAR
partitionName	string	Name of the disk partition that stores the MongoDB process database. Populated for Get Disk Partition Measurements only.
processId	string	FQDN and port of the MongoDB process.
start	string	Timestamp in ISO 8601 date and time format in UTC for the beginning of the period the returned measurements cover.
