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
:
# 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
:
# Disable sync.
sync_interval=0
