Grafana provides <https://grafana.com/docs/grafana/latest/features/datasources/prometheus/#query-variable> this function: *label*_*values(metric, label)* to get the label values for a specific metric only, which sounds like what you need - just pick one metric which has the network devices, and one metric which has the filesystem devices.
Looking at the source code <https://github.com/grafana/grafana/blob/master/public/app/plugins/datasource/prometheus/metric_find_query.ts#L58>, behind the scenes it calls /api/v1/series?match[]=*<metricname>* and then gets all the unique values of the label of interest. It's not quite as convenient as /api1/v1/label/<label>/values but easy enough to code. You *could* change the label names at ingestion time, by copying to a new label and dropping the old label, but I strongly recommend against this. It doesn't solve the problem in general - two different metrics may use the same label name for different purposes. It will be confusing, since the metrics stored in the database are different to those exported. Furthermore, you'll find yourself incompatible with any dashboards written to use the "correct" original label names. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
