Review DIAS panels in grafana

Notes from Mandana:
> Feedpositions analyzer is not reporting that it found a source
> On November 22nd, 10am, jumps reported 2200 jumps, and that is when the files processed momentarily dipped to 0.

Start by locating the DIAS Grafana panels and compare them with the two observations in the issue: the feedpositions analyzer not reporting a found source, and the reported jump spike coinciding with files processed dipping to zero. Determine whether the panels expose these events accurately; done means the noted discrepancies are addressed or clearly documented.
