    範例： 

    kubenode>get support-bundle file foo
Bundle file foo created in tgz format
kubenode>copy file foo url scp://[email protected]:/tmp
  • 將 NCP 記錄儲存在 Filestore 中

    記錄檔是以 tgz 格式儲存於 CLI 預設 Filestore 目錄 /var/vmware/nsx/file-store。您可以使用 CLI file-store 命令，將服務包檔案複製到遠端網站。 

    get ncp-log file <filename>

    範例： 

    kubenode>get ncp-log file foo
Log file foo created in tgz format
  • 將節點代理程式記錄儲存在 Filestore 中

    儲存來自一個節點或所有節點的節點代理程式記錄。記錄是以 tgz 格式儲存於 CLI 預設 Filestore 目錄 /var/vmware/nsx/file-store。您可以使用 CLI file-store 命令，將服務包檔案複製到遠端網站。
