用命令过滤MySQL慢查询日志

有一台web服务器异常.
CPU耗尽导致所有请求阻塞,偶发,一般持续时间5-10分钟.在该时间段,数据库整体负载正常.使用命令查询慢日志.
指定某个IP,找到查询时间大于100s,并且显示当时执行的SQL cat slow-log | sed "/#/{N;N;s/ //g}" | grep "Query_time: [1-9][0-9]{2}." -n20或者cat slow-log | sed "/#/{N;N;s/ //g}" | grep "127.0.0.1.*Query_time: [1-9][0-9]{2}." -A5 -bash-4.1$ cat slow-log | sed "/#/{N;N;s/ //g}" | grep "Query_time: [1-9][0-9]{2}."
