Abstract: A computer-readable medium comprises instructions which, upon execution by a node in a multi-node data processing system, enable the node to serve as a first leader node by receiving system log data from multiple compute nodes in a first cluster of the multi-node data processing system, and by saving the system log data in shared storage that is also used by second and third leader nodes to save system log data for compute nodes in second and third clusters of the multi-node data processing system.

The instructions may also enable the node to serve as a console bridge and to save console log data in the shared storage.

Upon receiving user input a change may be implemented. Throughout the editing session data provided to a client side application could be logically compressed to avoid redundant information from multiple sources being provided.
