OOS provides the configuration list feature for system administrators and O&M engineers. You can configure a configuration list for ECS instances in the OOS console to automatically collect system data, improve O&M efficiency, and simplify the monitoring process.
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
To use a configuration list to collect information, you must install a Cloud Assistant client of the latest version on the ECS instances from which you want to collect information. In most cases, a Cloud Assistant client of the latest version is installed on official images by default. For more information about how to check the version of the Cloud Assistant client that runs on an instance, see Install Cloud Assistant Agent.
You must use an account that is granted the required permissions on OOS. If you use an Alibaba Cloud account, ignore this note. If you use an account that is not granted the required permissions on OOS, you must grant the required permissions to the account. For more information, see Access control.
