Nagios 监控redis，简单又实用

首先介绍下怎么安装：

脚本用到了perl的Redis库,需要先安装这个：

# perl -MCPAN -e shell

# install Redis

1.wget http://farmerluo.googlecode.com/files/check_redis.pl

2.cp check_redis.pl /etc/nagios/command/

3.chown cacti.nagios check_redis.pl

在nagios内加入这个插件：

1.vi /etc/nagios/objects/command.cfg

2.# 'check_redis' command definition

3.define command{

4.command_name check_redis

5.command_line /etc/nagios/command/check_redis.pl -h $HOSTADDRESS$ $ARG1$

6.}

加入一个服务：

vi /etc/nagios/objects/linuxhost.cfg

define service{

use generic-service ; Name of service template to use

host_name rcs

service_description redis

check_command check_redis

notifications_enabled 1

}

检查下nagios配置是否正解：

nagios -v /etc/nagios/nagios.cfg

define command {

command_name check_redis_new

command_line $USER1$/check_redis.pl -H $HOSTADDRESS$ -p $ARG1$ -T $ARG2$ -R -A -M $_HOSTSYSTEM_MEMORY$ -m $ARG3$ -a $ARG4$ -w $ARG5$ -c $ARG6$ -f -P "$SERVICEPERFDATA$"

}

define service {

use prod-service

hostgroups redishosts

service_description Redis

check_command check_redis_new!5666!"1,2"!"80,90"!blocked_clients,connected_clients!50,~!100,~
