Ceph存储监控故障排除步骤

Ceph存储监控故障排除步骤

Ceph存储监控：

默认情况下，通过SSH添加Ceph监视器。所以如果客户想要监控服务器的Ceph存储，SSH必然是正常工作的状态。

支持的Ceph存储版本：>= v0.66

用于收集所有性能数据的命令：ceph -s -f json-pretty

对于任何数据收集的问题或身份验证的问题。

首先让客户运行ServerSSHTroubleshoot.sh/bat，检查SSH连接是否正常。如果SSH工作正常，则在远程机器上运行以下命令并检查输出，另外输出应为以下格式，否则您会在UI上看到错误消息“未收集性能数据，因为Ceph状态命令不返回输出”

ceph -s -f json-pretty

示例输出：
