nagios 通过Nagios-Plugins-Memcached插件监控memcached服务器

nagios通过 Nagios-Plugins-Memcached插件监控memcached服务器
插件需要Perl语言支持，建议到cpan直接下载。Nagios-Plugins-Memcached-0.02http://search.cpan.org/CPAN/authors/id/Z/ZI/ZIGOROU/Nagios-Plugins-Memcached-0.02.tar.gz１.　下载并安装插件wget http://search.cpan.org/CPAN/authors/id/Z/ZI/ZIGOROU/Nagios-Plugins-Memcached-0.02.tar.gzmv Nagios-Plugins-Memcached-0.02.tar.gz /usr/local/srccd /usr/local/srctar xzvf Nagios-Plugins-Memcached-0.02.tar.gzcd Nagios-Plugins-Memcached-0.0.2perl Makefile.plmake install２.　安装插件到nagioscp -av `whereis check_memcached` /opt/nagios/libexec/３.　检查插件是否可以正常工作找一台可以连通的memcached服务器，这里用192.168.88.60来测试# /opt/nagios/libexec/check_memcached -H 192.168.88.60
MEMCACHED OK - OK４.　配置nagios监控系统４.１　定义命令修改objects/commands.cfg，增加如下内容：# 'check_memcached' command definition
define command{
command_name check_memcached_response

command_line $USER1$/check_memcached -H $HOSTADDRESS$:$ARG1$ -w $ARG2$ -c $ARG3$
}

define command{
command_name check_memcached_size

command_line $USER1$/check_memcached -H $HOSTADDRESS$:$ARG1$ --size-warning $ARG2$ --size-critical $ARG3$
}

define command{
command_name check_memcached_hit

command_line $USER1$/check_memcached -H $HOSTADDRESS$:$ARG1$ --hit-warning $ARG2$ --hit-critical $ARG3$
}
４.２　定义主机和服务添加文件objects/memcached_01.cfg文件 define host{ use linux-box-remote host_name memcached_01 alias Memcached Server 01 address 192.168.88.60 }define service{ use generic-service host_name memcached_01 service_description Memcached01 check_command check_memcached_response!11211!30!40 }define service{ use generic-service host_name memcached_01 service_description Memcached02 check_command check_memcached_response!11212!30!40 }define service{ use generic-service host_name memcached_01 service_description Memcached01_size check_command check_memcached_size!11211!30!40 }define service{ use generic-service host_name memcached_01 service_description Memcached02_size check_command check_memcached_size!11212!30!40 }define service{ use generic-service host_name memcached_01 service_description Memcached01_hit check_command check_memcached_hit!11211!40!30 }define service{ use generic-service host_name memcached_01 service_description Memcached02_hit check_command check_memcached_hit!11212!40!30 }４.３　在nagios.cfg中引用objects/memcached_01.cfg配置vim /etc/nagios/nagios.cfg增加下面的行：cfg_file=/etc/nagios/objects/memcached_01.cfg４.４　选项操作推荐操作：定义一个专门的服务器对象监控目录，如objects/servers定义一个专门的服务对象监控目录，如objects/servicesvim /etc/nagios/nagios.cfg增加下面的行：cfg_file=/etc/nagios/objects/objects/serverscfg_file=/etc/nagios/objects/objects/services根据实际需要添加必要的配置文件到这两个目录。４.５　重新读取nagios配置并测试我们前边的操作/etc/init.d/nagios reloadmemcached监控页面
