Histograms provide a chronological view of the CPU, memory, disk, and terminal I/O use for each node, as well as node status information. Select histograms by specifying the HISTOGRAM option in the command line as follows:
$ ADVISE PERFORMANCE REPORT HISTOGRAMS
The data in histograms shows how the system is being used during the specified time interval. A shorter reporting period alters the scale of the histograms, providing finer resolution. This information helps you double-check some of the conclusions reached by the Performance Manager, including CPU and memory limitations.
