This topic describes how to use the CloudOps Orchestration Service (OOS) console to configure a configuration list for one or more required instances. This allows you to collect the data of these instances.
When you create a configuration list in the OOS console, the system performs the following operations at the backend: An OOS desired-state configuration template is created. The type of the configuration template is inventory. A data collection policy and the execution plan must be specified for the configuration template. The data collection policy includes the list types to be collected. The execution plan specifies the interval at which the configuration template is executed.
Limits
A Cloud Assistant client is required to collect the information that is specified in a configuration list. To collect the information of a configuration list, you must install a Cloud Assistant client of the latest version on the required ECS instance. By default, a Cloud Assistant client is installed on official images. This applies to most cases. If you want to check the version of the Cloud Assistant client that runs on the required instance, see How can I install a Cloud Assistant client?
You must use an Alibaba Cloud account that is granted the required permissions to manage OOS. If you use an account with administrator permissions, ignore the preceding note. If you use an account that is not granted the required permissions to manage OOS, you must grant these permissions to the account. For more information, see Use RAM to control access at the account level.
