promql - Custom Prometheus metrics not queryable

Question

I've got Prometheus running on a bare metal Ubuntu server, no Kubernetes or Docker. I want to monitor a custom hardware BrightSign Player (BSP) via their plugin extensibility solution. I've got the BSP endpoint returning what I believe to be a valid OpenMetrics, though I'm happy to be wrong if this is my problem.

The Targets screen in the Prometheus UI reports that the endpoint is up and I believe the syntax is correct because while developing when I did have a syntax error, there was a relevant error message on this page.

When I search for either of these metrics nothing is returned

This is the relevant bit of prometheus.yml

- job_name: 'bsp-001'
  static_configs:
  - targets: ['10.1.5.21:8081']

Is there something else necessary for custom metrics to be queryable in Prometheus? I'm brand new to this tool so don't assume I didn't miss something obvious. Thank you!
