一、环境概述

nagios服务端：192.168.203.10

nagios客户端（redis）：192.168.203.20

redis版本：Redis 2.8 release

二、下载并安装redis监控插件

https://github.com/willixix/WL-NagiosPlugins

将perl文件放到nagios的指定libexec路径下，赋执行权限

/usr/local/nagios/libexec/check_redis.pl

需要安装perl的Redis.pm模块，否则报错

(No output on stdout) stderr: Can‘t locate Redis.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /usr/local/nagios/libexec/check_redis.pl line 421. 

#yum install -y perl-YAML

#perl -MCPAN -e shell

cpan[1]> install Redis

一路回车，可能需要安装的依赖包太多，一直安装就好。

cpan[2]> quit

#cp -p /usr/local/share/perl5/Redis.pm  /usr/lib64/perl5/

三、定义监控命令

在commands.cfg添加下面内容：

#vi /usr/local/nagios/etc/objects/commands.cfg

# check redis

define command {

        command_name    check_redis

        command_line    $USER1$/check_redis.pl -H $HOSTADDRESS$ -p $ARG1$ -a $ARG2$ -w $ARG3$ -c $ARG4$ -f

}

定义主机监控项

#vi /usr/local/nagios/etc/objects/192.168.203.20.cfg

define service {

      use                     local-service

      service_description     Redis Client

      check_command           check_redis!6379!‘connected_clients,blocked_clients,client_longest_output_list,client_biggest_input_buf‘!100,5,~,~!500,10,~,~

      host_name               192.168.203.20

}

安装完成之后，具体情况如下：
