使用Nagios-Plugins-Memcached 进行监控memcached

监控memcache的运行状态有好几种实现方式。在这里我只介绍用Nagios-Plugins-Memcached 进行监控memcached。

该插件是用prel 进行开发的所以系统上必须要安装Perl 环境，并且同时保证服务器能够上网， cpanplugin 安装

CPAN的使用

默认情况下使用cpan命令安装时，如果依赖其他的软件包时cpan就会停止，但是如果使用CPANPLUS来进行安装时，就能能自动安装依赖项的模板

#cpan CPANPLUS

Are you ready for manual configuration? [yes]

CPAN build and cache directory? [/root/.cpan]

Cache size for build directory (in MB)? [10]

Perform cache scanning (atstart or never)? [atstart]

Cache metadata (yes/no)? [yes]

Your terminal expects ISO-8859-1 (yes/no)? [yes]

File to save your history? [/root/.cpan/histfile]

Number of lines to save? [100]

Policy on building prerequisites (follow, ask or ignore)? [ask]

Where is your gzip program? [/bin/gzip]

Where is your tar program? [/bin/tar]

Where is your unzip program? [/usr/bin/unzip]

Where is your make program? [/usr/bin/make]

Where is your links program? [/usr/bin/links]

Where is your wget program? [/usr/bin/wget]

Warning: ncftpget not found in PATH

Where is your ncftpget program? []

Warning: ncftp not found in PATH

Where is your ncftp program? []

Where is your ftp program? [/usr/kerberos/bin/ftp]

Where is your gpg program? [/usr/bin/gpg]

What is your favorite pager program? [/usr/bin/less]

What is your favorite shell? [/bin/bash]

2 首先下载Nagios-Plugins-Memcached-0.02.tar.gz，解压

wget http://search.cpan.org/CPAN/authors/id/Z/ZI/ZIGOROU/Nagios-Plugins-Memcached-0.02.tar.gz

#tar xvf Nagios-Plugins-Memcached-0.02.tar.gz

3 安装

#cd Nagios-Plugins-Memcached-0.0.2

#perl Makefile.pl

*** Module::AutoInstall version 1.03

*** Checking for Perl dependencies...

[Core Features]

- Carp::Clan ...missing.

- Cache::Memcached ...missing.

- FindBin ...loaded. (1.47)

- Nagios::Plugin ...missing.

- Time::HiRes ...loaded. (1.9717)

==> Auto-install the 3 mandatory module(s) from CPAN? [y]

#make install

4 查找安装后的check_memcached 的插件，并把该插件拷贝到nagios的插件的目录下面

#whereis check_memcached

#cp /usr/bin/check_memcached /usr/local/nagios/libexec

#chmod +x /usr/local/nagios/libexec/check_memcached

5 当然在用nagios 进行监控memcached 的方法方法分别是

首先定命令在nagios 命令文件command.cfg后面添加一下

define command{

command_name check_memcached_response

command_line $USER1$/check_memcached -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$

}

define command{

command_name check_memcached_size

command_line $USER1$/check_memcached -H $HOSTADDRESS$ --size-warning $ARG1$ --size-critical $ARG2$

}

define command{

command_name check_memcached_hit

command_line $USER1$/check_memcached -H $HOSTADDRESS$ --hit-warning $ARG1$ --hit-critical $ARG2$

}

6 定义主机

define host{

use linux-box-remote

host_name mysqllinux186

alias Memcache

address 192.168.1.186

}

define service{

use generic-service

host_name mysqllinux186

service_description Memcached

check_command check_memcached_response!30!40

}

define service{

use generic-service

host_name mysqllinux186

service_description Memcached_size

check_command check_memcached_size!30!40

}

define service{

use generic-service

host_name mysqllinux186

service_description Memcached_hit

check_command check_memcached_hit!40!30

}

#/usr/local/nagios/bin/nagio -v /usr/local/nagios/etc/nagios.cfg

检测配置文件是不是有错误，如果没有错误，并重启nagios
