nagios监控客户端
nagios服务端能检测客户端版本后，接下来的工作则是对客户端的监控，我的配置文件是这样操作的把所有的监控主机节点都放到hosts.cfg中，所有主机的服务都放到services.cfg中，如果日后要添加的话，则只需要改动这2个文件就可以了
cfg_file=/usr/local/nagios/etc/objects/templates.cfg
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg

【nagios客户端】，需要在nagios客户端先定义,/usr/local/nagios/libexec插件下的所有插件都必须要有执行权限，否则会报“NRPE: Command 'xx’ not defined”
command=/usr/local/nagios/libexec/check_users -w 5 -c 10
command=/usr/local/nagios/libexec/check_load -w 15,10,5 -c 30,25,20
command=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /dev/hda1
command=/usr/local/nagios/libexec/check_procs -w 5 -c 10 -s Z
command=/usr/local/nagios/libexec/check_procs -w 150 -c 200
command=/usr/local/nagios/libexec/check_procs -w 190 -c 200
command=/usr/local/nagios/libexec/check_http -H localhost -p 80

command=/usr/local/nagios/libexec/check_tcp -H 127.0.0.1 -p 5666
command=/usr/local/nagios/libexec/check_tcp -H 127.0.0.1 -p 3306
command=/usr/local/nagios/libexec/check_tcp -H 127.0.0.1 -p 9801
command=/usr/local/nagios/libexec/check_tcp -H 127.0.0.1 -p 9800
重启nrpe
【nrpe测试】在nagios服务器测试
./check_nrpe -H 122xx -c check_sda3
DISK OK - free space: / 876739 MB (98% inode=99%);| /=12366MB;749349;843018;0;936687
就可以了
