# 检查周期，默认为2分钟，对于网站来说有点长，可以根据需要自行调节，这改成30秒。
set daemon 30

include /etc/monit.d/*

# 日志文件
set logfile /var/log/monit.log

#
# 邮件通知服务器
#
#set mailserver mail.example.com
set mailserver localhost with timeout 30 seconds

#
# 通知邮件的格式设置，下面是默认格式供参考
#
## Monit by default uses the following alert mail format:
##
## --8<--
## From: monit@$HOST # sender
## Subject: monit alert -- $EVENT $SERVICE # subject
##
## $EVENT Service $SERVICE #
## #
## Date: $DATE #
## Action: $ACTION #
## Host: $HOST # body
## Description: $DESCRIPTION #
## #
## Your faithful employee, #
## monit #
## --8<--
##
## You can override the alert message format or its parts such as subject
## or sender using the MAIL-FORMAT statement. Macros such as $DATE, etc.
## are expanded on runtime. For example to override the sender:
#
# 简单的，这只改了一下发送人，有需要可以自己修改其它内容。
set mail-format { from: admin@xxxx }

# 设置邮件通知接收者。建议发到gmail，方便邮件过滤。
set alert xxx@xxxx

set httpd port 2812 and #设置http监控页面的端口
use address www.etufo.org # http监控页面的IP或域名
##allow localhost # 允许本地访问
##allow 203.82.90.239 # 允许指定IP访问
allow user:password # 访问用户名密码
