/etc/init.d/nagios restart
(/etc/init.d/xinetd restart 重启nsca,用于接收客户端的数据,端口为5667,接收数据出现问题时,需要重启)
2.nagios 配置文件编辑
(su - nagios编辑)
1)/usr/local/nagios/etc/objects/hostgroups.cfg中定义hostgroup,有时禁用host,需要在这里把相应主机注释掉
define hostgroup{
hostgroup_name NETWORK-DEVICE Group
alias NETWOKR_DEVICE
members FW01
}
2)/usr/local/nagios/etc/nagios.cfg (禁用主机注释掉相应主机配置文件)
cfg_file=/usr/local/nagios/etc/objects/DB1.cfg
3.检查配置,
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg用来检查配置是否有问题,
出现这样的说明没问题
