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,不过一般都会默认安装
[root@nodea soft]# which perl
/usr/bin/perl
下载下来后安装
[root@nodea soft]# tar xzvf Nagios-Plugins-Memcached-0.02.tar.gz
[root@nodea soft]# cd Nagios-Plugins-Memcached-0.02
[root@nodea Nagios-Plugins-Memcached-0.02]# perl Makefile.PL
执行后会出现一些提示让你选择,按照自己想法选或者一路回车都能通过
[root@nodea Nagios-Plugins-Memcached-0.02]# make
这时他会下载一些运行时需要的东西
[root@nodea Nagios-Plugins-Memcached-0.02]# make install
 
默认会把check_memcached文件放到/usr/bin/check_memcached
没关系 把他拷贝到nagios的libexec下
在commands.cfg里面加上这么几条(这里我没有把check_memcached装在memcached服务器上,而是通过Nagios的check_memcached直接去访问memcached服务器的11211端口,当然你也可以把他装在memcached服务器上利用check_nrpe来取他的值)
 
### check cache size ratio(bytes/limit_maxbytes[%]) for memcached    监控memcached的内存使用比例
define command {
        command_name check_memcached_size
        command_line /usr/local/nagios/libexec/check_memcached -H $HOSTADDRESS$:11211 --size-warning $ARG1$ --size-critical $ARG2$
        }
 
### check cache hit ratio(get_hits/cmd_get[%]) for memcached    监控memcached的命中率
define command {
        command_name check_memcached_hit
        command_line /usr/local/nagios/libexec/check_memcached -H $HOSTADDRESS$:11211 --hit-warning $ARG1$ --hit-critical $ARG2$
        }
 
define command {
        command_name check_traffic
        command_line $USER1$/check_traffic.sh -V 2c -C public -H $HOSTADDRESS$ -I 1 -w $ARG2$ -c $ARG3$ -K -B
        }
最后要在services.cfg里面加点东西
define service{
        use                             local-service-15x7,services-pnp
        host_name                       f1_Multi_Test_118.26.237.164
        service_description             Memcached Response
        servicegroups                   check_memcached_response
        check_command                   check_memcached_response!300!500
        max_check_attempts              2       #检测到故障后最大尝试次数
        normal_check_interval           1       #检测到故障后间隔多少分钟尝试重复连接
        retry_check_interval            1       #检检测到故障后每隔多少分钟发一次报警信息
        }
        define service{
        use                             local-service-15x7,services-pnp
        host_name                       f1_Multi_Test_118.26.237.164
        service_description             Memcached Size
        servicegroups                   check_memcached_size
        check_command                   check_memcached_size!90!95
        process_perf_data               1
        max_check_attempts              2       #检测到故障后最大尝试次数
        normal_check_interval           1       #检测到故障后间隔多少分钟尝试重复连接
        retry_check_interval            1       #检检测到故障后每隔多少分钟发一次报警信息
        }
        define service{
        use                             local-service-15x7
        host_name                       f1_Multi_Test_118.26.237.164
        service_description             Memcached Hit
        servicegroups                   check_memcached_hit
        check_command                   check_memcached_hit!10!5
        max_check_attempts              2       #检测到故障后最大尝试次数
normal_check_interval           1       #检测到故障后间隔多少分钟尝试重复连接
        retry_check_interval            1       #检检测到故障后每隔多少分钟发一次报警信息
        }
 
其他的可以按照自己要求添加..
好了,让我们重新启动下nagios服务
/etc/init.d/nagios restart
看看结果
 
呵呵好了,Nagios监控memcached基本就搞定了
