Reading the Previous Logs
Azurite keeps the code edit history separately for each session, where a session starts with the Eclipse IDE being opened and ends when the IDE is exited. By default, the Timeline View displays the history of the current session only.
In case you want to work with the history of previous sessions, you can manually invoke the Read Previous Logs command from the main menu, or the Timeline View toolbar.
When you invoke this command for the first time, Azurite will read the edit history of the past 5 sessions. It will read 5 more sessions each time you click the button.
In the Timeline View, at the right-most edge of each session, a gray vertical line is shown to indicate the boundary between the two adjacent sessions.
If you are concerned with the log files taking your hard drive space, please consider Cleaning up the Log Files.
