The xcxclus utility can generate a data file. The data for each monitored node is updated each
second. You can use this data file either to replay the data or to plot graphs of various node
performance statistics. For more information on plotting graphs with the xcxclus utility, see
“Plotting the Data from the xcxclus Datafiles” (page 76)
.
When you specify the -output option and a prefix, the xcxclus utility generates a data file
for all allocated nodes. The following example runs the xcxclus utility and stores the output
in a file, named test.xclus:
