We’ve been running Grafana for weeks with some InfluxDB databases that are being updated about once a second. The Grafana version is v5.4.3 (6539180).
Yesterday we started seeing issues with the graphs where several minutes of data was being cut off from the left side of graphs. This prevents the “Last 5 minutes” range from even showing any data at all.
The screen shots below show the same data at 15 minute and 30 minute ranges.
This behavior is seen in multiple dashboards using multiple InfluxDB databases.
The data is there – by varying the time ranges you can see all the data, but a few minutes are always cut off on the left side. I’ve also used queries and graphs in Chronograf to confirm that the data is definitely there.
I have tried restarting the Grafana service and even restarting the whole server.
Is this a Grafana bug or a global setting we’ve somehow changed?
Update: I’ve upgraded to V6.1.3 and I’m still seeing the same behaviour
