流程
查看集群日志：
使用 oc logs [-f] <pod_name> 命令，其中的 -f 是可选的。
oc logs -f <any-fluentd-pod> -n openshift-logging
$ oc logs -f <any-fluentd-pod> -n openshift-logging - 1
- 指定日志收集器 Pod 的名称。使用
-f选项可以跟踪正在写进日志中的内容。
例如：
oc logs -f fluentd-ht42r -n openshift-logging
$ oc logs -f fluentd-ht42r -n openshift-logging输出的日志文件内容。
默认情况下，Fluentd 从日志的末尾开始读取日志。
