Invalid /metrics output after adding new pipeline
Open, Needs TriagePublic

Description

The Prometheus exporter for ArcLamp broke when we added the excimer-buster pipeline. It contains lines with missing values, such as the following:

arclamp_newest_svg_seconds{period="hourly",profiler="excimer-buster",entry="all"}

I think this will fix itself once the graphs start being created; this task is to fix the underlying bug.
