使用mysqladmin extended-status查看MySQL的运行状态脚本

一个好用的使用mysqladmin extended-status查看MySQL的运行状态脚本：

mysqladmin -P3306 -uroot -p -h127.0.0.1 -r -i 1 extended-status |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\n",innodb_lor,innodb_phr);}}‘
