NetBox includes a housekeeping management command that should be run nightly. This command handles:

  • Clearing expired authentication sessions from the database
  • Deleting changelog records older than the configured retention time

This command can be invoked directly, or by using the shell script provided at /opt/netbox/contrib/ This script can be linked from your cron scheduler's daily jobs directory (e.g. /etc/cron.daily) or referenced directly within the cron configuration file.

sudo ln -s /opt/netbox/contrib/ /etc/cron.daily/netbox-housekeeping


On Debian-based systems, be sure to omit the .sh file extension when linking to the script from within a cron directory. Otherwise, the task may not run.

The housekeeping command can also be run manually at any time: Running the command outside scheduled execution times will not interfere with its operation.
