Today I tagged v0.2.0 of gstat_exporter, a Prometheus exporter for FreeBSD gstat(8) data: https://github.com/tykling/gstat_exporter/releases/tag/v0.2.0
It is available on PyPi now: https://pypi.org/project/gstat-exporter/
I have opened a PR to update the #FreeBSD port: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=275762
I have also updated the Grafana dashboard to use some more modern panels: https://grafana.com/grafana/dashboards/11223-freebsd-gstat-exporter/
I will tag v1.0.0 of gstat_exporter soon if no issues appear with the changes I've made over the last couple of days. If you use it please test! Thanks :)
