Hi, uploaded my scripts to https://github.com/sergey-senozhatsky/slabinfo A set of very simple bash scripts. The README file contains some sort of documentation and a 'tutorial'. ================================================================== To start collecting samples, record file name is NOMERGE, note sudo sudo ./slabinfo-plotter.sh -r NOMERGE #^C or reboot pre-process records file for gnuplot ./slabinfo-plotter.sh -p NOMERGE -b gnuplot File gnuplot_slabs-by-loss-NOMERGE File gnuplot_slabs-by-size-NOMERGE File gnuplot_totals-NOMERGE generate grphs from 'slabinfo totals' ./gnuplot-totals.sh -f gnuplot_totals-NOMERGE Graph file name -- gnuplot_totals-NOMERGE.png ... ================================================================== Two things: -- it wants a patched version of slabinfo (some sort of patches are in kernel_patches/ dir) -- it wants slabinfo to be in PATH For now on it does what it does -- captures numbers and picks only ones that are interesting to me and generates plots. I'm doing this in my spare time, but I'm surely accepting improvement requests/ideas, pull requests, and everything that follows. Will play around with the scripts for some time to make sure they are usable and then we can decide if there is a place for something like this in the kernel or it's better be done somehow differently. -ss -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
