我需要监控Windows服务(如CPU负载,内存使用等),所以我安装了Nagios监控工具.安装完成,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

我已经证实nagios工作正常,如下.

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

M新来的nagios,提前谢谢:)

解决方法:

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.确保您的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已打开.
