The firewall hardware is too slow to run the *prometheus_speedtest*
program. It always showed *way* lower speeds than were actually
available. I've moved the service to the Kubernetes cluster and it
works a lot better there.
*mtrcs0.pyrocufflink.red* is a Raspberry Pi CM4 on a Waveshare
CM4-IO-BASE-B carrier board with a NVMe SSD. It runs a custom OS built
using Buildroot, and is not a member of the *pyrocufflink.blue* AD
domain.
*mtrcs0.p.r* hosts Victoria Metrics/`vmagent`, `vmalert`, AlertManager,
and Grafana. I've created a unique group and playbook for it,
*metricspi*, to manage all these applications together.
