There is a command group 'az_dt_twin_telemetry'. This group of commands could 'test and validate the event routes and endpoints of a digital twins instance'. The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'. The group of commands has global parameter '--output -o' which means 'Output format.'. The group of commands has global parameter '--query' which means 'JMESPath query string. See <a href="http://jmespath.org/">http://jmespath.org/</a> for more information and examples.'. The group of commands has global parameter '--subscription' which means 'Name or ID of subscription. You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_dt_twin_telemetry_send'.The syntax is: az dt twin telemetry send --dt-name
                          --twin-id
                          [--component]
                          [--dt-id]
                          [--resource-group]
                          [--telemetry]
                          [--telemetry-source-time]. The 1th example of the child command would be to use it to 'send twin telemetry', the syntax is: az dt twin telemetry send -n {instance_or_hostname} --twin-id {twin_id}. The 2th example of the child command would be to use it to 'send twin telemetry with a custom telemetry source timestamp and message identifier', the syntax is: az dt twin telemetry send -n {instance_or_hostname} --twin-id {twin_id} --tst {telemetry_source_timestamp} --dt-id {dt_id}. The parameter '--dt-name --dtn -n' is required. It is used to digital twins instance name or hostname. if an instance name is provided, the user subscription is first queried for the target instance to retrieve the hostname. if a hostname is provided, the subscription query is skipped and the provided value is used for subsequent interaction.. The parameter '--twin-id -t' is required. It is used to the digital twin id.. The parameter '--component' is optional. the path to the dtdl component. if set, telemetry will be emitted on behalf of the component.. The parameter '--dt-id' is optional. a unique message identifier (in the scope of the digital twin id) that is commonly used for de-duplicating messages. if no value is provided a guid is automatically generated.. The parameter '--resource-group -g' is optional. digital twins instance resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--telemetry' is optional. inline telemetry json or file path to telemetry json. default payload is an empty object: {}.. The parameter '--telemetry-source-time --tst' is optional. an rfc 3339 timestamp that identifies the time the telemetry was measured..
