通过 prometheus. log 可以看到 prometheus data 文件读取 json output 失败，可以先确认下盘是否可用，比如 vi 保存文件。磁盘正常情况下，监控数据无用情况下，可以重新部署 prometheus，如下步骤： 1.先 mv 备份 Prometheus.2.0.2 .data.metrics 的目录 2.中控机 ansible-playbook -l 172.16.9.89 deploy. yml --tags prometheus 3.中控机 ansible-playbook -l 172.16.9.89 start. yml --tags prometheus

172.16.9.89中控机那台出此问题，终于解决了。非常谢谢
