二：告警系统配置文件

mon.conf内容
 ## to config the options if to monitor
## 定义mysql的服务器地址、端口以及user、password
to_mon_cdb=0? ?##0 or 1,default 0,0 not monitor,1 monitor
db_ip=10.20.3.13
db_port=3315
db_user=username
db_pass=passwd
## httpd? ?如果是1则监控，为0不监控
to_mon_httpd=0
## php 如果是1则监控，为0不监控
to_mon_php_socket=0
## http_code_502??需要定义访问日志的路径
to_mon_502=1
logfile=/data/log/xxx.xxx.com/access.log
## request_count? ?定义日志路径以及域名
to_mon_request_count=0
req_log=/data/log/www.discuz.net/access.log
domainname=www.discuz.net
