使用 MySQL status 查看是否還有 Query 進來

MySQL 想要看有沒有 Query 進來，使用 MySQL show processlist; 看紀錄可能不夠，要看 status 的數字比較準，不然微秒的看不見

使用 MySQL status 查看是否還有 Query 進來

MySQL status 看到詳細資訊如下：

mysql> status;
--------------

把一些雜訊去掉，大概要看的就是下述：

mysql> status;
--------------
Connection id: 1006466959
Server version: 5.6.32-78.1-log Percona Server (GPL)
Uptime: 1180 days 20 hours 11 min 36 sec
Threads: 3 Questions: 50320099254 Slow queries: 489806 Opens: 242974 Flush tables: 2 Open tables: 2048 Queries per second avg: 493.214

主要是看 Questions: 50320099254，這個數字若還有在增加，就代表有 Query 進來 (自己 status 應該也要算在裡面)
