High Disk usage on Netgate 5100

Hi everyone

This is my first post on the forum so hopefully all will make sense (no pun intended), and someone can help.

I have a NetGate 5100, and the disk usage seems to be really high as the box isn’t doing too much. I can’t see a way of reducing this or seeing where all the space is being taken.

Thanks again

What makes you think there is high usage or are you referring to the free space available?

Hi Tom


Sorry I am only just coming back as I appreciate your response.

Please see image attached.

I have an identical Firewall where both are doing the same but this one seems really high.


My assumption is that you may have adjusted the logging, here is the usage on my 6100 that is running, Suricata, HAProxy, ACME, Zabbix, 2 OpenVPN, One Wireguard, FreeRadius, & Tailscale.

Thanks Tom.

Is there a way to clear the space and getting the logging back to a normal state?

The system will self maintain but to do it manually you need to figure out what is taking up all the space.

Hi Tom,

Thank you for your help.

I thought I would just let you know that it turned out to be the size of the DB of ntopng.
