These are the new features, enhancements, and known and resolved issues for Edge Manager.

Predix Edge Manager Q1 2018 New Features

This release contains the following new features:

Partial BOM Deployments

When a BOM is updated and redeployed, packages specified in the BOM that are already installed on the device are skipped (not downloaded and deployed again). Only new packages are deployed to the device. The status of skipped packages is displayed as "installed" rather than "success."

This feature saves time and data when deploying BOMs.

Upload and Deploy Operating Systems
You can now upload operating systems to the Edge Manager Repository and deploy the OS to devices. You can check the status of the OS deployment in the Operations and Devices (in the Software tab) pages.
New Commands
New commands to help the administrator troubleshoot various issues have been added. The new commands include:
  • run_dpkg – Lists all packages installed on the device using system command dpkg.
    Note: This command is only for Linux devices that support dpkg.
  • run_ifconfig – Runs the system command ifconfig on the device and returns the command output.
    Note: This command is only for devices that support ifconfig.
  • run_top – Runs the system command top on the device for one iteration.
    Note: This command is only for devices that support top.
  • run_journalctl – Queries the default system journal on the device using system command journalctl according to the filtering and formatting values specified in the command parameters.
    Note: This command is only for Linux devices that support journalctl.
  • refresh_device_detail – Sends all device detail information in the next sync. This command overrides the Cloud Gateway's polling interval (com.ge.dspmicro.cloud.gateway.pollingInterval) and schedules a sync immediately.
See:
Device Troubleshooting Page
There is a new Troubleshooting tab in the device detail page that displays CPU, memory, and disk usage for the device.

See Troubleshooting Devices.

Enhancements

This release contains the following enhancements:

Increased File Size Limit
When uploading files, or packages, to the Edge Manager Repository, the size limit has increased to the following:
  • 500 MB for configuration, application, and containers
  • 15 GB for OS

Known Issues

This release contains the following known issues:

  • Issues with Firefox And Chrome browsers:
    • There is a plug-in conflict that causes the browser to crash (GE internal only) when downloading a file, or when viewing the output of a command.

      The same plug-in conflict causes an error when uploading a large file (hundreds of MB).

      Workaround:

      For Firefox: Run Firefox in Safe mode to disable Firefox plug-ins.

      For Chrome:
      1. Run Chrome in Incognito mode.
      2. In Settings > Extensions, if you have the DGExtension, ensure that it is disabled by unselecting the checkbox.
  • When you update a Docker container, the Execution Time in the Deployment Schedule does not get updated in Edge Manager. Start and End times are updated and displayed correctly.
  • Operations start, execution start, and elapsed time display differently for the top level versus operation details when there is only one operation. This is due to how the summary is calculated versus how the operation detail is calculated.
  • You can create groups with the same name as an existing group and attach it to the same parent.

    Workaround: To avoid creating groups with duplicate names, verify that there are no existing groups with the same name.

  • You cannot save a filter if the name has more than 63 characters.

    Workaround: Use fewer than 63 characters in filter names.

  • If a device is placed in inventory but not enrolled, and software or configuration packages are sent to that device, and one of the Edge Manager services fails and needs to be restarted, then those software or configuration packages may need to be redeployed to that device.
  • There is a known issue with deleting a group with a large number (over 5,000) of devices. Do not create such large groups, or move devices incrementally out of large groups so you can delete the group.
