Ops Manager v6.0 will EOL in January 2025. Upgrade to a higher Ops Manager version as soon as possible.

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://{OPSMANAGER-HOST}:{PORT}/api/public/v1.0

Resource

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

For 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.

For 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.

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.

For example:

../measurements?m=CONNECTIONS&m=OPCOUNTER_CMD&m=OPCOUNTER_QUERY

You must specify measurements that are valid for the host. Ops 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. Ops Manager adds the status field to the response body.

None

Request Body Parameters

This endpoint doesn't 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. For 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.
