There is a command group 'az_load_test run_metrics'. This group of commands could 'command group to retrieve load test run 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_metrics_get dimensions'.The syntax is: az load test-run metrics get-dimensions --load-test-resource
                                        --metric-definition-name
                                        --metric-dimension
                                        --metric-namespace
                                        --test-run-id
                                        [--end-time]
                                        [--interval]
                                        [--resource-group]
                                        [--start-time]. The 1th example of the child command would be to use it to 'get cpu metric dimension values for a given load test run', the syntax is: az load test-run metrics get-dimensions --test-run-id sample-test-run-id --load-test-resource sample-alt-resource --resource-group sample-rg --metric-namespace EngineHealthMetrics --metric-name CPU --metric-dimension EngineId. The 2th example of the child command would be to use it to 'get response time metric dimension values for a given load test run  time period and aggregation interval', the syntax is: az load test-run metrics get-dimensions --test-run-id sample-test-run-id --load-test-resource sample-alt-resource --resource-group sample-rg --metric-namespace LoadTestRunMetrics --metric-name ResponseTime --metric-dimension RequestName --start-time 2023-01-01T15:16:17Z --end-time 2023-01-01T16:17:18Z --interval PT5M. 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-definition-name --metric-name' is required. It is used to name of the metric.. The parameter '--metric-dimension' is required. It is used to value of the metric dimension.. The parameter '--metric-namespace' is required. It is used to namespace of the metric. allowed values: loadtestrunmetrics, enginehealthmetrics.. The parameter '--test-run-id -r' is required. It is used to test run id of the load test run.. The parameter '--end-time' is optional. iso 8601 formatted end time.. The parameter '--interval' is optional. iso 8601 formatted interval. allowed values: pt10s, pt1h, pt1m, pt5m, pt5s.. The parameter '--resource-group -g' is optional. name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--start-time' is optional. iso 8601 formatted start time..
