篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了zabbix监控告警Received empty response from Zabbix Agent Assuming that agent dropped connection相关的知识,希望对你有一定的参考价值。
昨天想监控下tomcat,在网上找到,配置好后,重启了下Server,然后告警就来了
Received empty response from Zabbix Agent at [192.168.2.203]. Assuming that agent dropped connection
全是这种,还不是端口错误。
搞了好久,最后还是看日志搞定的。
日志里有这样
30305:20170426:123707.943 failed to accept an incoming connection: connection from "192.168.2.199" rejected, allowed hosts: "127.0.0.1"
7084:20170425:181648.923 failed to accept an incoming connection: connection from "111.?.?.8" rejected, allowed hosts: "111.?.?.2"
我分析,公网的这些失败是出口有多个ip,而我只写了一个111.?.?.2,那它现在就从111.?.?.8出去,所以会报错,增加新ip后,重启agent,成功。
但是第一个127.0.0.1的,我一直没变过,也报错了,这个就不太清楚了,最后在配置文件和前台都改了server的ip为192.168.2.199后,才成功。
如有知道为什么的,麻烦告知下,谢谢了。
