本文介绍了一个用于监控MySQL服务器状态的Shell脚本。该脚本通过调用mysqladmin工具收集MySQL的各项性能指标，如查询数量(QPS)、命令执行状态、InnoDB行操作详情及缓冲池读取情况，并以表格形式展示这些数据。通过定期运行此脚本，可以快速了解MySQL实例的工作负载和健康状况。

[root@hank-yoon scrips]# vi mysqlstat.sh

/export/servers/mysql/bin/mysqladmin -P3306 -uyoon -pyoon -h127.0.0.1 -r -i 2 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\n",innodb_lor,innodb_phr);\
}}'
