I have a Prometheus data source, which is fed by a metrics endpoint scraped every 15 seconds. When I graph this in Grafana, it seems like the data is getting interpolated, similar to InfluxDB’s “fill(previous)”. I notice this in the form of one point being plotted every second, even though the backing data only has one point every 15 seconds.
I know I can change the resolution to something like 1/10, but then I see a point every 10 seconds, not every 15, which still seems wrong.
Is there a way I can show just the actual points that exist in Prometheus and not interpolated points?
Thanks!
