Each record in the system table indicates the resource usage of a user at a time point, including the memory, number of CPU cores, storage space, temporary space, operator flushing space, logical I/O traffic, number of logical I/O times, and logical I/O rate. The memory, CPU, and I/O monitoring items record only the resource usage of complex jobs. </p>
