在提交问题单时，向红帽提供包含有关集群的诊断信息会很有帮助。您可以使用 oc adm must-gather 工具为各种类型的资源收集诊断数据，如 TempoStack 或 TempoMonolithic，以及创建的资源，如 Deployment、Pod 或 ConfigMap。oc adm must-gather 工具会创建一个收集此数据的新 pod。
流程
从您要保存收集的数据的目录中，运行
oc adm must-gather命令来收集数据：oc adm must-gather --image=ghcr.io/grafana/tempo-operator/must-gather -- \ /usr/bin/must-gather --operator-namespace <operator_namespace>
$ oc adm must-gather --image=ghcr.io/grafana/tempo-operator/must-gather -- \ /usr/bin/must-gather --operator-namespace <operator_namespace>1 Copy to Clipboard Copied! Toggle word wrap Toggle overflow - 1
- 安装 Operator 的默认命名空间是
openshift-tempo-operator。
验证
- 验证新目录是否已创建并包含收集的数据。
