Each Exadata Storage cell can be monitored, configured, and maintained using the cellcli command line interface. To invoke the CLI, simply login to the Exadata cell as cellmonitor, celladmin, or root, and type “cellcli”. Within cellcli, a wide range of commands can be invoked to monitor the cell.
Using dcli
The cellcli commands in the previous section operate on the Cell server you’re logged in to. To obtain a cross-cell view of cell server configuration, metrics, alerts, and other information, you can use dcli (Distributed Command Line Interface). dcli is a Python script installed on each Exadata node that allows you to run Cell CLI commands on multiple cell server nodes at once.
In order or dcli to function, SSH user equivalency should be established to eliminate the need to supply the “celladmin” (or root/cellmonitor) Linux password on the cell servers.
