    Curious how others are handling this.

    I've got a 8192 MB RAM Disk for /var to prevent a ton of writes to my drive, which feels pretty generous, almost excessive.

    I've got notpng configured as such:
    3b18dc28-c76d-4e57-b421-7d5de793ebe8-image.png

    Regardless every couple of days I'm managing to overflow /var, and thus pfsense goes down hard.

    I really hate the idea of setting up influxdb in a VM on another box for this, is it possible to just segregate ntopng to something less critical than /var/? Ideally any package would not be writing to a shared RAM disk which could take down the entire system.

      @digitalgimpus ntopng writes a ton of data to disk. There is no way around this. To lessen it a bit, you could turn off the host time series data, and the interface data. But there will still be a ton of writes. Even if you use InfluxDB off host for the traffic data, there will still be a lot of local writes via Redis. In short, if you care about disk writes, do not run ntopng.

      FWIW, I recommend ntopng be used as a diagnostic resource when you have issues. I do not recommend ntopng as something you continuously run.
