There is a command group 'az_tsi_event source_eventhub'. This group of commands could 'manage event source with timeseriesinsights sub group event hub'. 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_tsi_event source_eventhub_update'.The syntax is: az tsi event-source eventhub update [--environment-name]
                                    [--event-source-name]
                                    [--ids]
                                    [--local-timestamp]
                                    [--resource-group]
                                    [--shared-access-key]
                                    [--subscription]
                                    [--tags]
                                    [--timestamp-property-name]. The 1th example of the child command would be to use it to 'updateeventhubeventsource', the syntax is: az tsi event-source eventhub update --environment-name "env1" --name "es1" --shared-access-key "someSecretvalue" --timestamp-property-name "someTimestampProperty" --resource-group "rg1". The parameter '--environment-name' is optional. the name of the time series insights environment associated with the specified resource group.. The parameter '--event-source-name --name -n' is optional. the name of the time series insights event source associated with the specified environment.. The parameter '--ids' is optional. one or more resource ids (space-delimited). it should be a complete resource id containing all information of 'resource id' arguments. you should provide either --ids or other 'resource id' arguments.. The parameter '--local-timestamp' is optional. an object that represents the local timestamp property. it contains the format of local timestamp that needs to be used and the corresponding timezone offset information. if a value isn't specified for localtimestamp, or if null, then the local timestamp will not be ingressed with the events. expected value: json-string/@json-file.. The parameter '--resource-group -g' is optional. name of resource group of environment. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--shared-access-key' is optional. the value of the shared access key that grants the time series insights service read access to the event hub. this property is not shown in event source responses.. The parameter '--subscription' is optional. name or id of subscription. you can configure the default subscription using `az account set -s name_or_id`.. The parameter '--tags' is optional. space-separated tags: key[=value] [key[=value] ...]. use "" to clear existing tags.. The parameter '--timestamp-property-name --ts-property-name' is optional. the event property that will be used as the event source's timestamp. if a value isn't specified for timestamppropertyname, or if null or empty-string is specified, the event creation time will be used..
