The exacli tool is a command-line interface that can be used to monitor and manage the storage servers in Exadata Database Service. The exacli tool provides access to the cellcli command, which is used to manage and monitor individual Oracle Exadata storage cells1. The exacli tool can also perform other tasks, such as checking the status of the storage server grid, viewing the configuration and performance metrics of the storage servers, and applying patches and updates to the storage servers2.
The other options are not tools that can be used to monitor a storage server in Exadata Database Service. The dbaascli tool is a command-line interface that can be used to perform various administrative tasks on the database servers, such as creating and deleting databases, managing backups and restores, and applying patches and updates3. The OCI CLI tool is a command-line interface that can be used to interact with Oracle Cloud Infrastructure services, such as creating and managing resources, configuring network and security settings, and accessing the Console4. The ocpucli tool is not a valid tool name, but it may be confused with the opctli tool, which is a command-line interface that can be used to manage Oracle Private Cloud Appliance, a converged infrastructure system that is not related to Exadata Database Service5.
