6.2. 在 Kibana 中查看集群日志

6.2. 在 Kibana 中查看集群日志

您可以在 Kibana web 控制台中查看集群日志。在 Kibana 中查看和视觉化您的数据的方法，它们超出了本文档的范围。如需更多信息，请参阅 Kibana 文档。

先决条件

必须安装 OpenShift Logging 和 Elasticsearch。
Kibana 索引模式必须存在。
用户必须具有 cluster-admin 角色、cluster-reader 角色或这两个角色，才能在 Kibana 中查看 infra 和 audit 索引。默认 kubeadmin 用户具有查看这些索引的权限。
如果可以查看 default、kube- 和 openshift- 项目中的 pod 和日志，则应该可以访问这些索引。您可以使用以下命令检查当前用户是否有适当的权限：
```
oc auth can-i get pods/log -n <project>
```
```
$ oc auth can-i get pods/log -n <project>
```

注意
默认情况下，审计日志不会存储在 OpenShift Container Platform 内部 Elasticsearch 实例中。要在 Kibana 中查看审计日志，您必须使用 Log Forward API 配置使用审计日志的 default 输出的管道。

流程

在 Kibana 中查看日志：

在 OpenShift Container Platform 控制台中点击 Application Launcher 并选择 Logging。
使用用来登录到 OpenShift Container Platform 控制台的相同凭证进行登录。
Kibana 界面将出现。
在 Kibana 中，点 Discover。
从左上角的下拉菜单中选择您创建的索引模式： app、audit 或 infra。
日志数据显示为时间戳文档。
展开一个时间戳的文档。

点 JSON 选项卡显示该文件的日志条目。
