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  120

1.2 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!
