There is a command group 'az_load_test run_server metric'. This group of commands could 'command group to manage load test run server metrics'. 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_load_test run_server metric_add'.The syntax is: az load test-run server-metric add --aggregation
                                   --app-component-id
                                   --app-component-type
                                   --load-test-resource
                                   --metric-id
                                   --metric-name
                                   --metric-namespace
                                   --test-run-id
                                   [--resource-group]. The 1th example of the child command would be to use it to 'add a server metric for an app component to a test run', the syntax is: az load test-run server-metric add --test-run-id sample-test-run-id --load-test-resource sample-alt-resource --resource-group sample-rg --metric-id "/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/Sample-rg/providers/Microsoft.Compute/virtualMachineScaleSets/sample-temp-vmss/providers/microsoft.insights/metricdefinitions/Percentage CPU" --metric-name  "Percentage CPU" --metric-namespace microsoft.compute/virtualmachinescalesets --aggregation Average --app-component-type Microsoft.Compute/virtualMachineScaleSets --app-component-id /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/sample-rg/providers/Microsoft.Compute/virtualMachineScaleSets/app-comp-name. The parameter '--aggregation' is required. It is used to aggregation to be applied on the metric.. The parameter '--app-component-id' is required. It is used to fully qualified resource id of the app component. for example, subscriptions/{subid}/resourcegroups/{rg}/providers/microsoft.loadtestservice/loadtests/{resname}.. The parameter '--app-component-type' is required. It is used to type of resource of the app component. refer https://learn.microsoft.com/cli/azure/resource#az-resource-show.. The parameter '--load-test-resource --name -n' is required. It is used to name or arm resource id of the load testing resource.. The parameter '--metric-id' is required. It is used to fully qualified id of the server metric. refer https://docs.microsoft.com/en-us/rest/api/monitor/metric-definitions/list#metricdefinition.. The parameter '--metric-name' is required. It is used to name of the metric. example, requests/duration.. The parameter '--metric-namespace' is required. It is used to namespace of the server metric. example, microsoft.insights/components.. The parameter '--test-run-id -r' is required. It is used to test run id of the load test run.. The parameter '--resource-group -g' is optional. name of resource group. you can configure the default group using `az configure --defaults group=<name>`..
