昨天想监控下tomcat,在网上找到,配置好后,重启了下Server,而后告警就来了
tomcat
Received empty response from Zabbix Agent at [192.168.2.203]. Assuming that agent dropped connectionide
全是这种,还不是端口错误。spa
搞了很久,最后仍是看日志搞定的。日志
日志里有这样server
30305:20170426:123707.943 failed to accept an incoming connection: connection from "192.168.2.199" rejected, allowed hosts: "127.0.0.1"ip
7084:20170425:181648.923 failed to accept an incoming connection: connection from "111.?.?.8" rejected, allowed hosts: "111.?.?.2"it
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,那它如今就从111.?.?.8出去,因此会报错,增长新ip后,重启agent,成功。io
可是第一个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。class
若有知道为何的,麻烦告知下,谢谢了。监控
