Code Samples for the Chrome Management Telemetry API

Visit Chrome Management Telemetry API for an overview of API features.

All the requests shown below use the following variables:

• $TOKEN - OAuth 2 token
• $CUSTOMER - ID of the customer or literal my_customer

List Telemetry Device Data

To list telemetry data for a chrome device use the /telemetry/devices endpoint. The readMask parameter is used to specify which device fields are returned. You can control pagination of the results using the pageSize and pageToken parameters. Specify a filter to further narrow down the results based off of device or report criteria.

Note: The readMask parameter is required for list requests. Only fields specified in the mask will be returned in the response. Also, requests that don't specify a reports_timestamp in the filter parameter will only return recent report data. Include reports_timestamp>=0 in the request to retrieve all report data.

List Telemetry Device Data Using a Timestamp Filter

The timestamp filter returns all devices, but only includes reports that conform to the timestamp filter and specified read_mask.

To use this filter, specify the reports_timestamp value in the filter parameter and include a timestamp value in either the Unix Epoch in milliseconds (ie. 1679288169623) or RFC 3339 "Zulu" formatted time (up to nine fractional digits ie. "2023-02-15T11:18:51.383Z") formats. Timestamps returned by the API are in the UTC timezone, so reports_timestamp filter values should also be in the UTC timezone. All standard number comparison operators (<, >, <=, >=, =) are supported.

Note: Requests without an explicit reports_timestamp filter will only return recent report data. Include reports_timestamp>=0 in the request to retrieve all report data.

List All Reports

Since only recent reports are returned when no reports_timestamp value is specified, the following call can be used to retrieve all device reports included in the read_mask for all devices.

  curl -X GET \
  -H "Authorization: Bearer $TOKEN" \
  "https://chromemanagement.googleapis.com/v1/customers/$CUSTOMER/telemetry/devices?readMask=name,customer,orgUnitId,deviceId,serialNumber,audioStatusReport,cpuStatusReport,heartbeatStatusReport,memoryStatusReport&filter=reports_timestamp>=0"

List Telemetry User Data

To list telemetry data for a chrome device use the /telemetry/users endpoint. The readMask parameter is used to specify which device fields are returned. You can control pagination of the results using the pageSize and pageToken parameters.

Note: The readMask parameter is required for list requests. Only fields specified in the mask will be returned in the response.

Request

List Telemetry Event Data

To list telemetry events for a customer, use the /telemetry/events endpoint. The readMask parameter is used to specify which fields are returned. In the near future, the readMask parameter will become optional, and the filter param with at least 1 event type will be required.

By default, the event's name, report_time, and event_type fields are included in the response. You can control pagination of the results using the pageSize and pageToken parameters. Additionally, you can filter results with the following parameters:

• device_id
• user_id
• device_org_unit_id
• user_org_unit_id
• timestamp
  • Input value can either be EPOCH milliseconds, ie timestamp<1667423821001 or RFC 3339, ie. timestamp<"2022-11-02T20:08:32.386Z"
• event_type
  • audio_severe_underrun
  • network_connection_state_change
  • usb_added
  • usb_removed
  • network_htps_latency_change

Note: Although the readMask parameter is currently required for list requests, it will be optional in the near future while the filter parameter with at least 1 event type specified will be required. Only fields specified in the mask or event type filter will be returned in the response.
