monit设置邮件频率和短信警报 原
June 3, 2013
一、monit 配置邮件发送频率
1.1 增加心跳周期 默认为60s 改为120s，可适当在增加
set daemon 1201.2 增加进程检测周期 将默认的：
check system 192.168.16.204
if loadavg (1min) > 6
if loadavg (5min) > 4
if memory usage > 95%
if swap usage > 95%
if cpu usage (user) > 95%
if cpu usage (system) > 95%
if cpu usage (wait) > 95% 改为如果三次（或更多）都达到警报条件则报警
check system 192.168.16.204
if loadavg (1min) > 6 for 3 cycles then alert
if loadavg (5min) > 4 for 3 cycles then alert
if memory usage > 95% for 3 cycles then alert
if swap usage > 95% for 3 cycles then alert
if cpu usage (user) > 95% for 3 cycles then alert
if cpu usage (system) > 95% for 3 cycles then alert
if cpu usage (wait) > 95% for 3 cycles then alert二、monit发短信警报
2.1 服务器安装curl
yum install curl查看rpm -qa|grep curl
2.2 发送短信脚本
#!/bin/bash
/usr/bin/curl -s -d api_id=XXXX -d user=XXXX -d password=**** -d to=86130******** -d "text=$*" "http://api.clickatell.com/http/sendmsg?"配置例子：
check host localhost with address 192.168.16.204
if failed port 25 type tcp with timeout 10 seconds for 2 times within 3 cycles then exec "/opt/sendsms localhost 192.168.16.204:25 connect failed!"当senmail 关掉后 会收到短信：localhost 192.168.16.204:25 connect failed!
