nagios监控memcached

Nagios的check_memcached
下载地址：

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

这个脚本是用perl编的，所以你要先确保自己的机器里面是否有perl环境.
安装方法:

#wget http://search.cpan.org/CPAN/authors/id/Z/ZI/ZIGOROU/Nagios-Plugins-Memcached-0.02.tar.gz
#tar xzvf Nagios-Plugins-Memcached-0.02.tar.gz
#cd Nagios-Plugins-Memcached-0.02
#perl Makefile.PL

执行后会出现一些提示让你选择,一路回车

#make

这时会下载一些运行时需要的东西

#make install

默认会把check_memcached文件放到/usr/bin/check_memcached
做个软链接抟到Nagios libexec目录下.

ln -s /usr/bin/check_memcached /usr/local/nagios/libexec/

测试
/usr/local/nagios/libexec/check_memcached -H192.168.0.40:12111
MEMCACHED OK – OK
如果提示没有Nagios::Plugin

可以通过CPAN来安装perl-nagios-plugin

perl -MCPAN -e shell
install File::Slurp
install YAML
install HTML::Parser
install URI
install Compress::Zlib
install Module::Runtime
install Module::Implementation
install Attribute::Handlers
install Params::Validate
install Nagios::Plugin

重新配置cpan的命令为”o conf init”

测试通过后修改nagios commands.cfg配置文件.加上这些内容:

define command {
command_name check_memcached_response
command_line $USER1$/check_memcached -H $ARG1$:$ARG2$ -w $ARG3$ -c $ARG4$
}
define command {
command_name check_memcached_size
command_line $USER1$/check_memcached -H $ARG1$:$ARG2$ –size-warning $ARG3$ –size-critical $ARG4$
}

define command {
command_name check_memcached_hit
command_line $USER1$/check_memcached -H $ARG1$:$ARG2$ –hit-warning $ARG3$ –hit-critical $ARG4$
}

然后在需监控主机的cfg配置文件里加上:

define service{
use local-service,srv-pnp ; Name of service template to use
host_name memcachedserver
service_description Memcached_response
check_command check_memcached_response!192.168.0.40!12111!300!500
}
define service{
use local-service,srv-pnp ; Name of service template to use
host_name memcachedserver
service_description Memcached_size
check_command check_memcached_size!192.168.0.40!12111!90!95
}
define service{
use local-service,srv-pnp ; Name of service template to use
host_name memcachedserver
service_description Memcached_hit
check_command check_memcached_hit!192.168.0.40!12111!10!5
}

/etc/init.d/nagios reload
重新reload后就可以看到,目前此插件不支持pnp作图
