Logging

This feature is a useful way of looking at the WEMS system's activity history, in order to understand trends and to look for ways to improve efficiency.

To view the system logs:

  1. Go to Tools | Logging.

A new browser window will open with options to view several different types of logs.

Viewing Logs As Text

By default, the log will be displayed in the main part of the screen in the form of a graph. If you wish to view the data as text, click View As Text in the bottom-right corner. Click View As Graph to revert to the previous view.

The Logging window in its alternative 'text' mode

Viewing the logs in 'text' mode can be useful should you ever need to keep a separate summary of activity. In 'text' mode the logged data is easy to copy and paste into a document or email.
