If multiple nodes contribute data to a graph, the graph is considered a composite graph. Data for each node can be added together, scaled by some factor, and added, or averaged. The method used depends on the metric being displayed. CPU percentages are scaled by CPU VUP rating, then added. Response times, I/O sizes, and disk space are averaged for each node and all other metrics are summed for each node.
To generate composite graphs, specify /COMPOSITE on the DCL command line, or if in command mode with more than one nodes data selected, omit the /NODE qualifier. When using Windows, the CLUSTER option or ALL NODES option generates the composite graph.
You can recognize a composite graph if there is more than one node listed in the subtitle.
Note: When you produce a composite Graph or Pie Chart and the nodes contribute data to the graph for different time periods (possibly missing data), the results are undefined. Composite Graphs and Pie Charts show accurate totals and averages when the data for the nodes correspond to the same time period.
