I updated my version of LibreNMS to 26.6.0 and there are “decent sized refactor to the rrd processes” – I’m seeing the following:
This is an issue with fontconfig
The advice I was given: “XDG_CACHE_HOME might help, but I’m not sure if that is the right fix…”
I first created a new directory (I’ve since discovered creating the directory is not necessary, adding the configuration item is sufficient):
[12:45 besser dvl /var/db/librenms] % sudo mkdir font-cache [12:45 besser dvl /var/db/librenms] % sudo chown www font-cache [12:51 besser dvl /var/db/librenms] % ls -l total 18 drwxr-xr-x 2 www www 2 2024.12.13 00:00 cache/ drwxr-xr-x 3 www www 3 2026.06.16 12:47 font-cache/ drwxrwxr-x 101 www www 101 2026.06.04 11:41 rrd/ drwxrwxr-x 6 www www 6 2026.01.24 16:22 storage/
The existing cache directory was empty. I’m not sure if that is a now-deprecated setting or not. I decided to create a new location outside that directory.
I added the following line to /usr/local/etc/librenms.env:
XDG_CACHE_HOME=/var/db/librenms/font-cache
Now I see:
I’ll put something into the FreeBSD port before I release it.
What’s in there? Not much.
