Named Telemetry Collections

Note: The nsfilter (namespace filter) query parameter is mandatory for every request. It sets the context, helping you look up resources within that namespace. Example: GET /itemsvc/api/v1/nameduseritems?nsfilter=proj_DrZrSNrW

Create Named Telemetry Collections#

Endpoints#

POST /itemsvc/api/v1/nameduseritems

Parameters#

Query#

Parameter	Type	Description	Required
`transactional`	Boolean	Set to true to make the request transactional.	Optional
`nsfilter`	String	namespace context	Required

Request#

Request body#

Parameter	Type	Description	Required
`_name`	String	Readable long-form name	Required
`_shortName`	String	An abbreviated name up to 22 characters that is used for reference	Required
`_description`	String	Describes the purpose of the NamedTelemetryCollection	Required
`_namespaces`	String	An array of namespaces you want to add the NamedTelemetryCollection to	Required
`_userType`	String	A user-defined type for the NamedTelemetryCollection that you can use to distinguish or group it by.	Required
`_itemClass`	String	Enter `"NamedTelemetryCollection"`.	Required
`_tsProperties`	Object	Pass an object with `_granularity` and `_expiry` properties.	Optional
`_tsProperties._granularity`	String	Enter one of the following options: `"seconds"`, `"minutes"`, `"hours"`. The default is `"minutes"`. The granularity defines the closest match to the time span between consecutive incoming measurements. If you ingest data from a given sensor once every 5 minutes, enter `"minutes"`.	Optional
`_tsProperties._expiry`	String	Enter an expiry time in seconds to automatically delete added readings after.	Optional

Expiry#

_expiry doesn't guarantee that expired data deletes immediately upon expiration. It is also controlled by_granularity as in below table. Data expire only when _ts crossed both covered time span and _expiry. For example, if you have granularity as hours and _expiry as 1 day it is possible that the data stays till 30 days from _ts

granularity	Covered Time Span
seconds	one hour
minutes	24 hours
hours	30 days

GET /itemsvc/api/v1/nameduseritems

Request#

Query parameters#

Parameter	Type	Description	Required
`query`	Object	Pass a query object with query parameters and values based on the NamedTelemetryCollection class. You can also use query operators. To query all versions of NamedTelemetryCollection rather than just the latest versions, add the query property and value `_versions.all: true`. For query examples, see Query parameter examples.	Optional
`project`	Object	Field projections to exclude or include fields in the response, for example, `project={"_metadata":0}`.	Optional
`page`	Object	Pass a Page object that defines the response pagination, for example, `?page={"_offset": 0, "_pageSize" 100}`	Optional
`sort`	Object	Pass a sort object to define the response sort order by a given property, using `1` for ascending sort and `-1` for descending sort, for example, `?sort={"_name":1}`	Optional
`userItemVersionId`	Object	Lookup RelatedItems for a given NamedTelemetryCollection version, rather than the current version.	Optional
`nsfilter`	String	namespace context	Required

Examples:

# searches by name, the response would have tip version only:?query={"_name": "General Medical Sensor data"}
# searches by item class, has all the versions?query={"_itemClass": "NamedTelemetryCollection","_versions.all":true}
# searches against all the versions and returns all the versions matching?query={"$and": [{"_itemClass": "NamedTelemetryCollection"},{"_versions._userAttributes.key":"value"}],"_versions.all":true}
