Hey Kevin - In addition to all the good stuff Richard provided, be aware that
you need to set $USE_XANADU = 1; in bin/runbench to enable the Xanadu
post-processing of the data.
In your profile (.prof file), set the function to generic_xanadu to enable
additional statistics gathering;
# cat oltp-zfs1.prof
DEFAULTS {
runtime = 60;
dir = /zfs/zp2/zspace2;
stats = /filebench/tstats;
filesystem = zfs;
description = "ZFS ZPOOL2 8k";
}
CONFIG large_db_oltp_8k_uncached {
personality = oltp;
function = generic_xanadu;
cached = 0;
directio = 1;
iosize = 8k;
nshadows = 200;
ndbwriters = 10;
usermode = 20000;
filesize = 1g;
memperthread = 1m;
workingset = 0;
}
Note the function entry in the CONFIG section.
Then edit bin/runbench to set $USE_XANADU, and you'll get extra system
statistics, nicely formatted for viewing in a WEB browser.
What happens is, when the run completes, in the stats directory (defined in the
DEFAULTS section of the .prof file), you'll have a subdirectory with a long
name (nodename-file system-prof file name-date and time). In that directory
will be another directory with the name of the CONFIG
(large_db_oltp_8k_uncached in the example above). In that directory is an html
directory, with an index.html file, and a bunch of PNG bitmap files of graphs
of all the collected statistics. Point a browser to the index.html file, and
just click on the links to get the graphs.
It's very slick, and hugely simplifies the process of gathering and comparing
results.
Please let us know if you have further questions.
