以check_tcp为例，前提已经配置好nagios及监控的主机。1、使用插件可以先出查看命令定义文档是如何使用这个命令的，vim /usr/local/nagios/etc/objects/commands.cfg2、经过上步还不明白可以查看帮助文件,各个参数的作用/usr/local/nagios/libexec/check_tcp –help3、在客户端使用使用该命令测试[root@zhilei libexec]# /usr/local/nagios/libexec/check_tcp -H
192.168.18.66 -p 80TCP OK – 0.000 second response time on port
80|time=0.000416s;;;0.000000;10.0000004、测试成功后增加监控主机的监控服务即可，要写上相应的变量，
具体如下所示。5、check_udp用法同check_tcp，仅以check_tcp举例。vim /usr/local/nagios/etc/objects/commands.cfg# ‘check_tcp’ command definitiondefine command{command_name??? check_tcpcommand_line??? $USER1$/check_tcp -H $HOSTADDRESS$ -p
$ARG1$ $ARG2$}
定义服务/usr/local/nagios/etc/objects/localhost.cfgdefine service {host_name?????? 你监控的主机名service_description???? apachecheck_period??? 24×7normal_check_interval?? 2retry_check_interval??? 1max_check_attempts????? 5notification_period???? 24×7notification_options??? w,u,c,rcheck_command?? check_http!80
}
重启nagios服务[root@zhileilibexec]# service nagios restartRunning configuration check…done.Stopping nagios: done.Starting nagios: done.
