Logs
Logs persistence
The logs are not persisted on reboot and will therefore be lost.
By default, logs are stored to RAM and are not kept over a reboot. This is because intensive logging on persistent memory (NAND memory) will reduce the longevity of the memory.
If you need persistent logging, please check the Persisting logs page.
Only the 10 latest files (2MB) are kept. The older logs are deleted.
Consult the logs
The logs are store in the /var/log/messages file.
You can display the logs using less:
You can also displaying in live new incoming messages with tail:
To avoid too large files, a new file is created when it reaches 200KB. The old file is automatically renamed with an index as suffix. After some time, you may have:

Inconsistent chronological order
If you have a log that does not follow a correct chronological order regarding the date/time information (for example steps of multiple hours at some moments) it is probably related to timezone change.
The time information in the logs has no timezone information. So when you change the timezone, the new logs can appear "before" regarding the time information. Keep in mind that the display order is always the correct chronological order.
