Requesting and Downloading Diagnostics from a Charger

Diagnosing charger issues often requires reviewing the device's internal logs. eMabler provides a convenient way to retrieve diagnostics packages directly from chargers via the platform UI. These logs are sent to an FTP server for further analysis.

Prerequisites

Ensure the following before proceeding:

• Charger is Online
  The charger must be connected and communicating with the eMabler platform.

• FTP Server URL
  A destination URL where the charger will upload the diagnostics package.

  • Example format: ftp://username:password@host

• eMabler Support FTP Server (Optional)
  You can request access credentials from eMabler Support.

• FTP Client Installed
  Required to download the diagnostics package from the FTP server.

  • For macOS: Install via Homebrew if not already available.

Sending a Diagnostics Request via eMabler UI

1. Navigate to the Charger
   Open the charger’s page and click "Details".

2. Open the Actions Menu
   Click "Actions" in the top-right corner.

3. Request Diagnostics
   Select "Send Diagnostics" from the dropdown.

4. Provide FTP URL
   Enter the full FTP URL in the format:

   CODE

   ftp://username:password@host 

5. Wait for Confirmation
   Once the charger completes the upload, a confirmation message appears in "Last Message".

   Example confirmation message:

   CODE

   [   2,   "35123123-asd23-243x-ba12-0141fc",   "DiagnosticsStatusNotification",   { "status": "Uploaded" } ] 

Downloading Diagnostics Using Terminal FTP Client

1. Open Terminal
   Launch your terminal application.

2. Connect to FTP Server

   CODE

   ftp username@host 

3. Enter Password
   When prompted, enter the corresponding password.

4. Enable Binary Mode

   CODE

   ftp> binary 

5. List Files

   CODE

   ftp> ls 

   Look for a file named with a pattern containing the charger ID and date.

6. Download the File

   CODE

   ftp> get <filename> 

7. Exit FTP Session

   CODE

   ftp> quit 

   You should now have a .zip diagnostics package on your machine.

Fixing Broken ZIP Packages

Some chargers may generate ZIP archives missing essential directory metadata, leading to extraction errors.
Common error:

pgsql

CopyEdit

End-of-central-directory signature not found.

How to Fix It (macOS Terminal)

Use the zip utility to repair the archive:

zip -FF broken.zip --out fixed.zip 

• Replace broken.zip with the path to the downloaded file.

• fixed.zip will be the rebuilt and usable archive.

You can now extract it using standard ZIP tools.

Additional Tips

• For recurring diagnostics, automate FTP uploads with scheduled tasks or support scripts.

• Always verify charger status before requesting logs to avoid incomplete uploads.

• Contact eMabler support for help with credentials or troubleshooting FTP issues.
