Use the isi_gather_info (isi_gather_info – incremental) command to provide a snapshot of the cluster to look at node communication and state. A folder is created for each node which contains the /var/log messages devices connected and files open. If there is no full gather, the system will run a full gather. If there is a full gather, you can perform an incremental gather. This takes much less space since it only records changes from the last time the full gather was run.
I need to gather detailed information about the cluster but I don't like using the GUI.  How can I do this?
