prometheus 服务器重启后之"Error on ingesting samples that are too old or are too far into the future&q

背景描述：aws中的prometheus实例状态检查出现异常，重启实例后实例正常，此时发现grafana中主机为空，经查看日志发现如下：

解决方法：

备份prometheus数据库，新建data目录，重启prometheus和grafana服务
[root@prometheus /opt/prometheus]# mv data/ data_bak
[root@prometheus /opt/prometheus]# mkdir -pv data && chown -R prometheus.prometheus data
[root@prometheus /opt/prometheus]# systemctl restart prometheus
[root@prometheus /opt/prometheus]# systemctl restart grafana-server

web界面访问prometheus正常，grafana访问正常
