1 The following is a demonstration of the dexplorer program.
4 Here we run dexplorer with no arguments. By default it will sample various
5 system activities using DTrace at 5 seconds per sample. It creates an
6 output tar.gz file containing all the DTrace output,
9 Output dir will be the current dir (/export/home/root/DTrace/Dexplorer).
10 Hit enter for yes, or type path:
11 Starting dexplorer ver 0.70.

34 File is de_jupiter_200506271803.tar.gz
36 As each sample is taken, a line of output is printed above. The above example
37 is for version 0.70, newer versions of dexplorer are likely to print more
38 lines as they take more samples.
40 The final line states which file all the output is now in.
