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：
