We use the pt-pmp (a variety for pmp !http://poormansprofiler.org/! by Percona ) tool a lot to analyze our online MySQL problem.
But when we execute the pmp, we have found tps/qps of mysqld drop a lot, such as:
143,148d142 < if gdb -nx --quiet --batch --readnever > /dev/null 2>&1; then < readnever=--readnever < else < readnever= < fi < 205c199 < gdb $readnever -ex "set pagination 0" -ex "thread apply all bt" -batch -p $OPT_p >> "${OPT_k:-$TMPDIR/percona-toolkit}" --- > gdb -ex "set pagination 0" -ex "thread apply all bt" -batch -p $OPT_p >> "${OPT_k:-$TMPDIR/percona-toolkit}"
