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.

Request

  curl -X GET \
  -H "Authorization: Bearer $TOKEN" \
  "https://chromemanagement.googleapis.com/v1/customers/$CUSTOMER/telemetry/devices?readMask=name,customer,orgUnitId,deviceId,serialNumber,cpuInfo,cpuStatusReport,memoryInfo,memoryStatusReport,osUpdateStatus&pageSize=2"

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 (milliseconds) or RFC 3339 "Zulu" formatted time (up to nine fractional digits) formats. Timestamps returned by the API are in UTC timezone, so reports_timestamp filter values should ideally also be in the UTC timezone.

Request

  curl -X GET \
  -H "Authorization: Bearer $TOKEN" \
  "https://chromemanagement.googleapis.com/v1/customers/$CUSTOMER/telemetry/devices?readMask=name,customer,orgUnitId,deviceId,serialNumber,cpuStatusReport,memoryStatusReport,osUpdateStatus&filter=reports_timestamp=\"2023-02-15T11:18:51.383Z\""

The reports_timestamp value can either be RFC 3339 "Zulu" formatted (ie. "2023-02-15T11:18:51.383Z", double quotes included) or Unix Epoch in milliseconds (ie. 1679288169623). All standard number comparison operators (<, >, <=, >=, =) are supported.

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
