  • 一个简易的mysql性能查询脚本

    #!/bin/sh
    mysqladmin -S /tmp/mysql3306.sock -p'123456' -r -i 1 ext |
    awk -F"|"
    "BEGIN{ count=0; }"
    '{ if($2 ~ /Variable_name/ && ((++count)%20 == 1)){
    print "----------|---------|--- MySQL Command Status --|----- Innodb row operation ----|-- Buffer Pool Read --";
    print "---Time---|---QPS---|select insert update delete| read inserted updated deleted| logical physical";
    }
    else if ($2 ~ /Queries/){queries=$3;}
    else if ($2 ~ /Com_select /){com_select=$3;}
    else if ($2 ~ /Com_insert /){com_insert=$3;}
    else if ($2 ~ /Com_update /){com_update=$3;}
    else if ($2 ~ /Com_delete /){com_delete=$3;}
    else if ($2 ~ /Innodb_rows_read/){innodb_rows_read=$3;}
    else if ($2 ~ /Innodb_rows_deleted/){innodb_rows_deleted=$3;}
    else if ($2 ~ /Innodb_rows_inserted/){innodb_rows_inserted=$3;}
    else if ($2 ~ /Innodb_rows_updated/){innodb_rows_updated=$3;}
    else if ($2 ~ /Innodb_buffer_pool_read_requests/){innodb_lor=$3;}
    else if ($2 ~ /Innodb_buffer_pool_reads/){innodb_phr=$3;}
    else if ($2 ~ /Uptime / && count >= 2){
    printf(" %s |%9d",strftime("%H:%M:%S"),queries);
    printf("|%6d %6d %6d %6d",com_select,com_insert,com_update,com_delete);
    printf("|%6d %8d %7d %7d",innodb_rows_read,innodb_rows_inserted,innodb_rows_updated,innodb_rows_deleted);
    printf("|%10d %11d ",innodb_lor,innodb_phr);
    }}'

    输出如下显示:

    [root@mysql-zst ~]# sh mysql.sh
