zabbix监控nginx日志自动发现

能够监控到日志中客户端链接响应时间和响应返回码，监控超过十秒的50.100.1000的个数，监控响应时间的平均数，监控响应返回码的个数，分别是302.404.502nginx日志格式：

|   log_format upstream2 '$remote_addr $remote_user [$time_local] "$request" $http_host'
        '$body_bytes_sent "$http_referer" "$http_user_agent" $ssl_protocol $ssl_cipher'
        '$request_time [$status] [$upstream_status] [$upstream_response_time] "$upstream_addr"'; 

是指从Nginx向后端（php-cgi)建立连接开始到接受完数据然后关闭连接为止的时间。发现脚本：

[root@RACK_Proxy_black_list /etc/zabbix/scripts]# cat nginx-log_analysis.py 
#!/usr/bin/env python
