Loki (as Prometheus datasource) getting Job and Filename as a filter / variable for panel

Grafana Loki

Have Loki as log DB and promtail pushing content (What an marvelous piece of software :+1:). Prometheus as a datasource, to my understanding via LOKI datasource you cannot get list of jobs and files to dashboard variables?

Almost there but not quite.
I can get jobs listed with this query
label_values(job)

How to list all File(s) from Loki? and filtered by chosen Job.

Silence… perhaps picture helps. Here are jobs from LOKI, how to get files? (filtered by job)

@jengstro it’s likely you do not need this answer anymore but for others that may come across this as documentation is still sparse, I was able to set the query as such using Loki as source:

label_values({compose_project="$compose_project"}, job)
