1. Scope:

  • This project is based on COVESA/DLT-Daemon

  • The aim of this project is to create a plugin used for log viewing on website. The plugin is first used for local network and then can be enhance for online update (might be realtime).

2. Background:

  • First, the idea is to simply build a tool helping user or client view the log data stored inside the system. The tool must contain a feature helping browse action and can upload the log file onto web page. Then the web page will be written in HTML.

3. Requirements and Limits:

a. Requirements:

  • Web page (UI) must be user-friendly and be able to detect correctly the log files.

  • The plugin can upload and convert binary file into ascii (human readable text).

  • The plugin must obey the COVESA standard log construction format.

  • The header and the payload must be considered as separate parts and be processed sequentially before uploading on Web.

b. Limits:

  • The plugin should be programmed using native Javascript instead of back-end runtime environment NodeJS or Javascript plugin JQuery.

  • The procedural scripts must be separated and put into different js file so that they can be hidden from users, instead of coding directly onto HTML file.

  • The lack of Javascript deeper knowledge might not seem to be a big matter but it is still a little struggling and challenging to manage searched information and Internet resources.

  • Some features or functions might not be supported by some web browsers.

4. Languages and tools:

  • Javascript

  • HTML

  • VScode

  • Web browsers (Google Chrome, Firefox)

5. Enhancement:

  • Please feel free to comment to this part for further investigation and enhancement. = Intern of DLT can start with this project to enhance basic DLT logging mechanism.
