zabbix 监控偶遇问题一记-张森纳-51CTO博客

收藏   我要投稿

现象:在zabbix web 端,JMX 显示红色,并且提示 cannot reslove 192.168.100.107,192.168.100.108......当时第一时间想到的是,将server端的 /etc/zabbix/zabbix_server.conf 中 JavaGateway 后的 ip 只保留 192.168.100.107,然后重启 zabbix-server

可是JMX还是显示红色,并且出现了“,(Connection refused): service:jmx:rmi:///jndi/rmi://192.168.100.107:9999/jmxrmi” 的问题解决方法:到 192.168.100.107 下去

我发现,tomcat完全关不掉,那么只有 kill 掉了

再重启 tomcat,最好同时重启 zabbix-java-gateway 和 zabbix-agent

同样的方法,将其他有问题的 tomcat 机器重启,就应该可以了zabbix 监控偶遇问题一记

总结:zabbix 不通时,检查服务端 /usr/zabbix/zabbix_server.conf 中的配置,再检查各客户端 tomcat 的状态
