There is a command group 'az_tsi_environment_gen1'. This group of commands could 'manage a gen1 environment in the specified subscription and resource group'. 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_environment_gen1_update'.The syntax is: az tsi environment gen1 update [--data-retention-time]
                               [--environment-name]
                               [--exceeded-behavior {pauseingress, purgeolddata}]
                               [--ids]
                               [--no-wait]
                               [--resource-group]
                               [--sku]
                               [--subscription]
                               [--tags]. The 1th example of the child command would be to use it to 'environmentsgen1update', the syntax is: az tsi environment gen1 update --name "env1" --sku name="S1" capacity=2                --resource-group "rg1" --data-retention-time "P30D" --storage-limit-exceeded-behavior PurgeOldData. The parameter '--data-retention-time' is optional. iso8601 timespan specifying the minimum number of days the environment's events will be available for query.. The parameter '--environment-name --name -n' is optional. name of the environment.. The parameter '--exceeded-behavior --storage-limit-exceeded-behavior' is optional. the behavior the time series insights service should take when the environment's capacity has been exceeded. if "pauseingress" is specified, new events will not be read from the event source. if "purgeolddata" is specified, new events will continue to be read and old events will be deleted from the environment. the default behavior is purgeolddata.. 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 '--no-wait' is optional. do not wait for the long-running operation to finish.. 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 '--sku' is optional. the sku determines the type of environment, either s1 or s2. for gen1 environments the sku determines the capacity of the environment, the ingress rate, and the billing rate.. 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..
