We noticed recently that in some of our visualizations the values for our data drops to 0 for random amounts of time and then comes back. Initially I started to look at metricbeats which we use to ship metrics to elasticsearch however after digging deeper in grafana it looks like the data is there and grafana is not displaying it correctly. I’m unsure if this is a grafana issue or a data issue but right now I’m leaning towards grafana.
