如何使用集群内对象存储 (Ceph) 收集 DU 使用情况数据

本节说明在使用集群内对象存储 (Ceph) 时如何收集 Document Understanding (DU) 使用情况数据。

采取以下步骤：

在运行 DU 收集器脚本之前，请确保更新以下值：
- <REGISTRY>:
  - 使用localhost:30071进行离线部署。
  - 使用registry.uipath.com进行在线部署。
  - 将您的外部注册表 URL 用于私有注册表。
- <TAG> ：打开versions.json并找到sf-k8-utils-rhel图像标签。使用此标签替换脚本中的<TAG> 。

更新值后运行 DU 使用情况收集器脚本，如下所示：

NAMESPACE="rook-ceph"
POD_NAME="du-usage-collector"
SECRET_NAME="ceph-object-store-secret"
LOCAL_TAR="du-usage.tar.gz"

检索存档后，删除 Pod：

kubectl delete pod "$POD_NAME" -n "$NAMESPACE"kubectl delete pod "$POD_NAME" -n "$NAMESPACE"

du-usage.tar.gz文件包含 DU 使用情况数据。
