The Files area contains features relating to the process of getting data files on to your cluster, managing these files and also the workunits associated with them including:

  • Logical files storage information including searching, manipulation and viewing of files and Superfile manipulation
  • File upload/download and spraying
  • DFU workunits including search
  • XREF

Browse Space Usage has moved to the Operations area and is now called Disk Usage.

Click on an image to see it full size. If you aren't displaying this in full screen mode, you may need to expand the window horizontally to see the accompanying text. Or hide the sidebar using the icon above .

Logical Files list can be viewed in two ways. Firstly, the list initially shows the list of all files. The actions that were previously shown in a drop down list or as buttons are now available as menu items.

Secondly, you can browse the logical files list by scope by clicking on the View by Scope icon to the right of the Filter. Toggle between these two modes using this button.

The Remote Copy feature is accessed from this page, providing the ability to copy from another DALI.

Searching of logical files is done using the Filter which refreshes the list according to your search criteria. Note that the Filter is not available when using the View by Scope mode.

Clicking on a file link opens a new tab showing the logical file details for the file you selected. You can open the details page for multiple files using the checkboxes on the Logical Files list and clicking Open. A menu is provided for the actions. Logical file details previously accessed via links on the page are now displayed on individual tabs.

Multiple files can be selected using the checkboxes on the main logical files page. A tab is opened for each file selected.

Use the Contents tab to view the data included in a logical file.

The Filter feature shows all fields specified in that file which can be used to display only those records you want to view.

This feature was known as View Data File in Legacy ECL Watch.

View the Queries tab to see all queries associated with a logical file.

Clicking on the query link displays details about the query and tabs providing information, graphs, and test pages for that query.

A link to the WUID associated with the query is also shown on the Queries tab providing access to all the ECL workunit information without needed to go back to the ECL area. This information is also available under the Workunit tab.

Superfiles are handled in much the same way as before. Creation of superfiles is done via the Logical Files list. Viewing the contents of a superfile is much simpler now, just click on it in the list. A new tab is opened showing its details and from there you can remove files and add a description.

To add more files to a superfile:

  1. Go back to the Logical Files list
  2. Select the files and Add to Superfile
  3. Check the Append box.
  4. Click Add.
  5. On viewing the superfile, you may need to Refresh to see the updated contents.

Physical and logical file management and spraying are now dealt with in the Landing Zones area. Go here to view the files already on your landing zone, upload/download files and spray files onto your Thor cluster.

The Preview:Hex feature shows the contents of a file on the landing zone in hex for the first 32k. This is useful, for example, for viewing fixed length files to help you determine the record length.

For the purposes of this guide, the hex preview information is shown on a separate page. However, it appears on a separate tab which you can see on this image next to the Landing Zones tab.

You can now add a file to your dropzone from another machine or HPCC dropzone. The Add File utility requires the IP address and path for the file you want to add.

The multi-file spray feature provides significant improvements and benefits in this area. It is useful for spraying a number of files of the same type to the same scope using the same spray options. 

However, fixed files can have different record lengths and XML files can have different row tags which must be specified individually for each file.

  1. Simply select the files you want to spray
  2. Select the spray type and you will see the files listed.
  3. Enter the record length or row tag information for each file if using the Fixed or XML spray types
  4. Check all other applicable options.
  5. Click Spray.

The example shows a fixed spray with mutiple files, each one has a different record length value.

ECL Watch now provides easier links to information about a DFU workunit and its associated logical file information.

Go to the Files area and click on a DFU workunit ID. This opens up a page with tabs showing the related XML and the Target tab which provides access to a range of related information for example:

  • The logical file Summary page.
  • The Contents of the data file
  • The list of Queries associated with the logical file.
  • The location details of the logical File Parts.


Searching the DFU workunits list is done using the Filter which refreshes the list showing DFU Workunits matching your search criteria.

  • No labels
