1、mysqladmin
使用mysqladmin extended-status命令可以获得所有MySQL性能指标，即show global status的输出，不过，因为多数这些指标都是累计值，如果想了解当前的状态，则需要进行一次差值计算，这就是mysqladmin extended-status的一个额外功能，非常实用。
默认的，使用extended-status，看到也是累计值，但是，加上参数-r(--relative)，就可以看到各个指标的差值，配合参数-i(--sleep)就可以指定刷新的频率
如果是5.7可以对mysqladmin进行配置
[mysqldump]user=rootpassword=123456
简单的命令
mysqladmin -r -i 1extended-status
监控脚本
#!/bin/bash#author [email protected]mysqladmin extended-status -i1|awk 'BEGIN{local_switch=0} $2 ~ /Queries$/ {q=$4-lq;lq=$4;} $2 ~ /com_commit$/ {c=$4-lc;lc=$4;} $2 ~ /Com_rollback$/ {r=$4-lr;lr=$4;} $2 ~ /Com_select$/ {s=$4-ls;ls=$4;} $2 ~ /Com_update$/ {u=$4-lu;lu=$4;} $2 ~ /Com_insert$/ {i=$4-li;li=$4;} $2 ~ /Com_delete$/ {d=$4-ld;ld=$4;} $2 ~ /Innodb_rows_read$/ {irr=$4-lirr;lirr=$4;} $2 ~ /Innodb_rows_deleted$/ {ird=$4-lird;lird=$4;} $2 ~ /Innodb_rows_inserted$/ {iri=$4-liri;liri=$4;} $2 ~ /Innodb_rows_updated$/ {iru=$4-liru;liru=$4;} $2 ~ /Innodb_buffer_pool_read_requests$/ {ibprr=$4-libprr;libprr=$4;} $2 ~ /Innodb_buffer_pool_reads$/ {ibpr=$4-libpr;libpr=$4;} $2 ~ /Threads_connected$/ {tc=$4;} $2 ~ /Threads_running$/ {tr=$4; if(local_switch==0) {local_switch=1; count=16} else { if(count>15) { count=0; print "------------------------------------------------------------------------------------------------------------------------------------ "; print "Time-----| QPS | Commit Rollback TPS | select insert update delete | read inserted updated deleted | logical physical | Tcon Trun"; print "------------------------------------------------------------------------------------------------------------------------------------ "; }else{ count+=1; printf "%s | %-5d| %-6d %-7d %-5d| %-7d %-7d %-5d %-6d| %-7d %-7d %-7d %-7d| %-6d %-9d| %-4d %-2d \n", strftime("%H:%M:%S"),q,c,r,c+r,s,u,i,d,irr,ird,iri,iru,ibprr,ibpr,tc,tr; } }}'
输出结果如下
