Zabbix故障现象： Zabbix agent on Zabbix server is unreachable for 5 minutes故障!
zabbix版本号：3.0.9
zabbix-检测中-事件 查看如下：
查看 more /var/log/zabbix/zabbix_agentd.log
20916:20170726:200017.136 the system time has been pushed back, adjusting active check schedule
20916:20170727:150005.872 the system time has been pushed back, adjusting active check schedule
20916:20170727:163106.058 the system time has been pushed back, adjusting active check schedule
经过查看zabbix_agentd.log日志可以看出是由于系统时间推迟不准导致zabbix报错。
解决措施：
#ntpdate pool.ntp.org
#
hwclock --systohc
