QPS (Query per second) （每秒查詢量）

TPS(Transaction per second) （每秒事務(wù)量，如果是InnoDB會(huì)顯示，沒有InnoDB就不會(huì)顯示）

計(jì)算方法

QPS Questions = SHOW GLOBAL STATUS LIKE 'Questions'; Uptime = SHOW GLOBAL STATUS LIKE 'Uptime'; QPS=Questions/Uptime TPS Com_commit = SHOW GLOBAL STATUS LIKE 'Com_commit'; Com_rollback = SHOW GLOBAL STATUS LIKE 'Com_rollback'; Uptime = SHOW GLOBAL STATUS LIKE 'Uptime'; TPS=(Com_commit + Com_rollback)/Seconds QPS mysqladmin -h192.168.160.100 -uroot -p extended-status --relative --sleep=1|grep -w Questions TPS :下面兩個(gè)值相加 Com_commit=mysqladmin -h192.168.160.100 -uroot -p extended-status --relative --sleep=1|grep -w Com_commit Com_rollback=mysqladmin -h192.168.160.100 -uroot -p extended-status --relative --sleep=1|grep -w Com_rollback TPS = $Com_commit + $Com_rollback

統(tǒng)計(jì)QPS、TPS的腳本

#!/bin/bash mysqladmin -uroot -h192.168.160.43 -p'000000' extended-status -i1|awk 'BEGIN{local_switch=0;print "QPS Commit Rollback TPS Threads_con Threads_run \n------------------------------------------------------- "}$2 ~ /Queries$/ {q=$4-lq;lq=$4;}$2 ~ /Com_commit$/ {c=$4-lc;lc=$4;}$2 ~ /Com_rollback$/ {r=$4-lr;lr=$4;}$2 ~ /Threads_connected$/ {tc=$4;}$2 ~ /Threads_running$/ {tr=$4;if(local_switch==0) {local_switch=1; count=0}else {if(count>10) {count=0;print "------------------------------------------------------- \nQPS Commit Rollback TPS Threads_con Threads_run \n------------------------------------------------------- ";}else{ count+=1;printf "%-6d %-8d %-7d %-8d %-10d %d \n", q,c,r,c+r,tc,tr;}} }'
