Grafana data points issue:

[spark cipher]

https://github.com/grafana/grafana/issues/113263
Does anyone have the same issue?
Does Grafana automatically aggregate or average the data (for example, into 5-minute intervals) when showing longer time ranges?
Can we set the query options interval to a fixed value like 1m?

@spark cipher when visualizing time ranges in Grafana, Grafana selects one data point per step size. This step size differs depending on time range selection and graph size in UI. You can try changing Min step param in time series panels but that is very tricky to get it right for different time ranges.

@sharp crag Can I set the Max Points to a biger value and it can change the interval to shorter time?

[sharp crag]

Max points is controlled via panel size.

[spark cipher]

selects one data point per step size?
For example the query interval is 5m , Grafana would randomly pick a point within this 5 min?

[sharp crag]

You can check step size in network tool. Query interval 5 minute is different to step size

[spark cipher]

I tried changing the max data points to bigger value, and when the query interval changed from 5m to 1m, the time series dashboard looks normal with righ pattern.

For a time series, This is what I have in my notes. This is a for a specific size of time range panel.

[sharp crag]

Changing these to static values may work for a time rnage and then it doesn't for others.

[spark cipher]

Yes, and it would take more time for loading the dashboard.
Do you know how does Grafana pick the data point?
Randomly pick a point or avg the values?

My understanding is it's the first or last point picked in the step size.

Thanks Rahul!!!
Seems to be a heavily requested issue
