nginx访问日志获取访问前10的url

在ELK里面获取top10的url在日志量非常大的情况下是非常消耗内存的，所以写了一个脚本用来快速获取。

配置文件 log.conf

[log]
log_file = /data/logs/nginx/access_all.log

[id_rsa]
id_rsa = /root/.ssh/id_rsa

程序log.py

#!/usr/bin/env python

        ssh.connect(hostname=self.host, port=self.port, username=self.username, pkey=self.private_key)
        stdin, stdout, stderr = ssh.exec_command(self.command)
        ret, err = stdout.read(), stderr.read()

    ret = log.mostrequests()
    print ret
