The Clear Linux* OS telemetry client provides an admin tool called telemctl that is used for managing the telemetry services and probes. The tool is located in /usr/bin. Running it with no argument results in the following:

sudo telemctl
/usr/bin/telemctl - Control actions for telemetry services
  stop       Stops all running telemetry services
  start      Starts all telemetry services
  restart    Restarts all telemetry services
  is-active  Checks if telemprobd and telempostd are active
  opt-in     Opts in to telemetry, and starts telemetry services
  opt-out    Opts out of telemetry, and stops telemetry services
  journal    Prints telemetry journal contents. Use -h argument for more

telemctl commands:


The commands to start, stop and restart the telemetry services manage all required services and probes on the system. There is no need to separately start/stop/restart the two client daemons telemprobd and telempostd. The restart command option will call telemctl stop followed by telemctl start .


The is-active option reports whether the two client daemons are active. This is useful to verify that the opt-in and opt-out options have taken effect, or to ensure that telemetry is functioning on the system. Note that both daemons are verified.

sudo telemctl is-active
telemprobd : active
telempostd : active

Opt-in to telemetry

To opt-in to the telemetry services, simply enter the opt-in command and start the service:

sudo telemctl opt-in

This removes the file /etc/telemetrics/opt-out file, if it exists, and starts the telemetry services.


To opt-in but not immediately start telemetry services, you will need to run the command sudo telemctl stop after the opt-in command is entered. Once you are ready to start the service, enter the command sudo telemctl start.

Opt-out of telemetry

To stop sending telemetrics data from your system, opt out of the telemetry service:

sudo telemctl opt-out

This creates the file /etc/telemetrics/opt-out and stops the telemetry services.
