收集MySQL测试脚本

#!/bin/sh
INTERVAL=5
PREFIX=$INTERVAL-sec-status
RUNFILE=/home/benchmarks/running
mysql -e 'SHOW GLOBAL VARIABLES' >> mysql-variables
while test -e $RUNFILE; do
  file=$(date +%F_%I)
  sleep=$(date +%s.%N | awk "{print $INTERVAL - (\$1 % $INTERVAL)}")
  sleep $sleep
  ts="$(date +"TS %s.%N %F %T")"
  loadavg="$(uptime)"
  echo "$ts $loadavg" >> $PREFIX-${file}-status
  mysql -e 'SHOW GLOBAL STATUS' >> $PREFIX-${file}-status &
  echo "$ts $loadavg" >> $PREFIX-${file}-innodbstatus
  mysql -e 'SHOW ENGINE INNODB STATUS\G' >> $PREFIX-${file}-innodbstatus &
  echo "$ts $loadavg" >> $PREFIX-${file}-processlist
  mysql -e 'SHOW FULL PROCESSLIST\G' >> $PREFIX-${file}-processlist &
  echo $ts
done
echo Exiting because $RUNFILE does not exist.

对测试数据分析脚本

#!/bin/sh
# This script converts SHOW GLOBAL STATUS into a tabulated format, one line
# per sample in the input, with the metrics divided by the time elapsed
# between samples.
awk '
  BEGIN {
    printf "#ts date time load QPS";
    fmt = " %.2f";
  }
  /^TS/ { # The timestamp lines begin with TS.
    ts = substr($2, 1, index($2, ".") - 1);
    load = NF - 2;
    diff = ts - prev_ts;
    prev_ts = ts;
    printf "\n%s %s %s %s", ts, $3, $4, substr($load, 1, length($load)-1);
  }
  /Queries/ {
    printf fmt, ($2-Queries)/diff;
    Queries=$2
  }
  ' "$@"
