16 Typically one would then use the ``slabinfo`` command to get statistical
17 data and perform operation on the slabs. By default ``slabinfo`` only lists
18 slabs that have data in them. See "slabinfo -h" for more options when
19 running the command. ``slabinfo`` can be compiled with
22 gcc -o slabinfo tools/mm/slabinfo.c
24 Some of the modes of operation of ``slabinfo`` require that slub debugging
127 ``slabinfo -a`` displays which slabs were merged together.
133 order to do so you must have the ``slabinfo`` tool. Then you can do
136 slabinfo -v
141 In that case ``slabinfo -v`` simply tests all reachable objects. Usually
322 Extended slabinfo mode and plotting
325 The ``slabinfo`` tool has a special 'extended' ('-X') mode that includes:
330 Additionally, in this mode ``slabinfo`` does not dynamically scale
332 also available to other slabinfo modes via '-B' option) which makes
335 output can be plotted using the ``slabinfo-gnuplot.sh`` script. So it
341 a) collect slabinfo extended records, for example::
343 while [ 1 ]; do slabinfo -X >> FOO_STATS; sleep 1; done
345 b) pass stats file(-s) to ``slabinfo-gnuplot.sh`` script::
347 slabinfo-gnuplot.sh FOO_STATS [FOO_STATS2 .. FOO_STATSN]
349 The ``slabinfo-gnuplot.sh`` script will pre-processes the collected records
356 Another use case, when ``slabinfo-gnuplot.sh`` can be useful, is when you
358 modification. To help you out there, ``slabinfo-gnuplot.sh`` script
364 while [ 1 ]; do slabinfo -X >> STATS<X>; sleep 1; done
368 slabinfo-gnuplot.sh STATS1 STATS2 .. STATSN
370 c) Execute ``slabinfo-gnuplot.sh`` in '-t' mode, passing all of the
373 slabinfo-gnuplot.sh -t STATS1-totals STATS2-totals .. STATSN-totals
378 can go unnoticed. To deal with that, ``slabinfo-gnuplot.sh`` has two
