Zabbix 收到空的返回

laoadiy

Zabbix有几天没有用，昨天发现服务都起来之后页面一直是红色的，但是log里边没有报错，Graphs 里边没有数据收到


配置文件说明，现在客户端和服务器在一台机器，
[root@hack etc]# egrep -v '(^$|^#)' zabbix_server.conf
LogFile=/tmp/zabbix_server.log
DBName=zabbix
DBUser=zabbix
DBPassword=zabbix
Include=/usr/local/zabbix/etc/zabbix_server.conf.d/*.conf
CacheSize=256M
StartPollers=5
[root@hack etc]# egrep -v '(^$|^#)' zabbix_agentd.conf
LogFile=/tmp/zabbix_agentd.log
Server=127.0.0.1
ServerActive=127.0.0.1
Hostname=Zabbix server
[root@hack etc]#

有知道哪里有问题的么 请指点，关键是log里边没有报错信息
Received empty response from Zabbix Agent at [127.0.0.1]. Assuming that agent dropped connection because of access permissions.
Received empty response from Zabbix Agent at [192.168.4.15]. Assuming that agent dropped connection because of access permission
