monit配置文件

监控模式：(MONITRING MODE)

Monit支持三种监控模式，

active--Monitj监控一个服务，为了防止一系列问题，Monit会执行以及发送警报，停止，启动，重启，这是一个缺省的模式

passive--MOnit监控一个服务，不会尝试去修复这个问题，但还是会发送警报

manual--Monit监控进入active模式，通过monit的控制，比如在控制台执行命令，比如 Monit start sybase

 

  (Monit will call sybase's start method and enable monitoring)

 

 

ALERT MESSAGES

Monit会发送一个邮件提醒，在下列情况

 

o A service timed out
 o A service does not exist
 o A service related data access problem
 o A service related program execution problem
 o A service is of invalid object type
 o A program status failed
 o A icmp problem
 o A port connection problem
 o A resource statement match
 o A file checksum problem
 o A file size problem
 o A file/directory timestamp problem
 o A file/directory/filesystem permission problem
 o A file/directory/filesystem uid problem
 o A file/directory/filesystem gid problem
 o An action is done per administrator's request

 

Monit 会发送一个警报只要被监控对象发生了改变，这些对象包括

 

 

 o Monit started, stopped or reloaded
 o A file checksum changed
 o A file size changed
 o A file content match
 o A file/directory timestamp changed
 o A filesystem mount flags changed
 o A process PID changed
 o A process PPID changed

 

 

警报状态有两种形式

Global -- common for all services

local -- per service

在没一种形式下你都可以发送多个警报状态，换句话说你可以发懊恼过不同的邮件到不同的地址

Setting a global alert statement

{

   如果在监控服务发生了改变，Monit将会发送一个警报到全局列表的所有的接受者，下面是全局警报的语法

   SET ALERT mail-address [[NOT]{EVENTS}]  [MAIL-FORMAT {mail-format}] [REMINDER number]

   简单使用：set alert foo@bar

  EVENTS，MAIL-FORMAT，REMINDER看下面使用用法

 Setting a local alert statement

 每一个服务可以有他自己的接收列表

ALERT mail-address [[NOT]{EVENTS}]  [MAIL-FORMAT {mail-format}] [REMINDER number]

没有了SET就成了局部的了

或者NOALERT  mail-address

如果你只想接受某些服务的某些警报信息的话，比如你只想接受timeout或者nonexist事件，那么你可以这么写

 

check process myproc with pidfile /var/run/my.pid
   alert foo@bar only on { timeout, nonexist } 
   ...

 

 

你可以指定除去某些事件外发送警报信息，比如你想监听所有时间除了instance事件，那么你可以这么写

 

 check system myserver
   alert foo@bar but not on { instance } 
   ...

 

相当于

 

 

  alert foo@bar on { action
                      checksum
                      connection
                      content
                      data
                      exec
                      fsflags
                      gid
                      icmp
                      invalid
                      nonexist
                      permission
                      pid
                      ppid
                      resource
                      size
                      status
                      timeout
                      timestamp
                      uid
                      uptime }

 

一个instance事件是指Monit程序启动或者停止

 

你也可以根据事件的不同来发送给不同的邮件

 

 alert foo@bar { nonexist, timeout, resource, icmp, connection }
 alert security@bar on { checksum, permission, uid, gid }
 alert manager@bar

 

可以在邮件过滤器中使用的事件如下：

 

action,checksum, connection, content, data, exec, fsflags, gid, icmp,instance, invalid, nonexist, permission, pid, ppid, resource, size, status, timeout, timestamp, uid, uptime

 

你可以使用

 

noalert appadmin@bar来进行不接受警报的邮箱

 

 

 

set alert foo@bar
 
 check process myfoo with pidfile /var/run/myfoo.pid
   ...
 check process mybar with pidfile /var/run/mybar.pid
   alert foo@bar only on { timeout }
