Nagios监控memcached

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
