Nagios - 连接被拒绝和套接字超时



我需要监控windows服务(如CPU负载、内存使用情况等),所以我安装了Nagios监控工具。安装已完成,并且还安装了"check_nt"插件。到目前为止,没有任何错误,但在使用代理NSClient++执行脚本时,"主机拒绝连接"错误仍然存在。

./check_nt -H 10.112.32.78 -p 1248 -v MEMUSE -w 80 -c 90
              Connection refused by host
./check_nt -H 10.112.32.78 -p 1248 -v MEMUSE -w 80 -c 90
              Socket timeout after 10 seconds

我已经验证了nagios是否正常工作,如下所示。

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

M是nagios的新手,提前感谢:)

连接被防火墙阻止,或者Nagios服务器不在"允许的主机"字段的nsc.ini文件中。确保windows防火墙上的端口以及Nagios服务器和客户端之间的任何其他网络过滤器都是打开的。

通过在Windows cmd:中发出此命令,确保要监视的Windows服务器/主机正在侦听NRPE端口5666和NT端口12489

netstat -aon | findstr 5666
netstat -aon | findstr 12489

可能是Windows防火墙也在拒绝这些端口上的连接,看看这一点。

另外,将Nagios监控服务器的ip地址添加到位于此处的NSClient++配置文件的allowed_hosts中:

C:Program FilesNSClient++

此外,在NSClient++的安装过程中,check_nt有一个复选框,请确保在安装过程中也选中了该复选框。

从NSClient++编辑配置文件后,请确保重新启动NSClient++服务。(在services.msc或"开始">"程序">"NSClient++">"停止NSClient++,然后"开始">"程序">NSClient++>"启动NSClient++)

根据您的linux风格,可以很容易地在谷歌上搜索命令。

安装必要的nagios debian包

apt-get-install nagios镜像nagios nrpe插件nagios nrpe服务器nagios插件nagios插件基本nagios插件标准nagios3nagios3cgi-nagios3commonnagios3-core

我刚刚在centos 7中遇到了一个问题。经过几个小时的搜索和与同一网络上的其他服务器的比较,我准备放弃

我确实比较了两者之间的nrpe.cfg,肯定有允许主机的IP,所有插件都是rsync的,权限都是一样的。我遇到的一个问题是远程登录到nrpe端口5666

telnet working_server_ip 5666工作

telnet not_working_server_ip 5666连接被拒绝。

我花了一段时间,但不知怎么的,我遇到了两个操作系统,一个工作是centos6,另一个是centos7。

如果你在centos7上安装nrpe,请确保你禁用了防火墙,我说的不是SELinux

systemctl停止firewalld

然后重试
