ram-journal

Efficiently in-memory log manager

Ram journal is a system that considerably reduces disk read and write operations by keeping logs from the /var/log directory in memory. It works in two ways:

Sync mode(default)

In this mode, logs are kept in memory and are synced to disk every 24 hours. The sync interval can be changed by setting the sync_interval in /etc/ram-journal/ram-journal.conf: ```ini

Sync to disk every 12 hours.

sync_interval=12 ```

/etc/ram-journal/ram-journal.conf

Ephemeral mode(default)

In this mode, logs are kept only in memory and are lost after a system reboot.

To disable the sync, set sync_interval to 0 in /etc/ram-journal/ram-journal.conf: ```ini

Disable sync.

sync_interval=0 ```
