How does aggreagation work in graffana?

  • What Grafana version and what operating system are you using?
    v7.5.7

  • What are you trying to achieve?
    have a 2 minutes(low granularity) graph and then be able to aggregate that up for the per day view.

  • How are you trying to achieve it?
    Using grafana graphs and panels

  • What happened?
    I have a low granularity graph (at 2mins) that has one spike of value 3 but then when I want to aggregate this for a day view I don’t get 3, I get 5 and it is the same search just changed interval to 1d.

  • What did you expect to happen?
    I expect in the 1 day view graph to show 3, as a bar chart or line. No matter the visulaisation the value should be the same.

  • Can you copy/paste the configuration(s) that you are having problems with?

graphs are exactly the same with only difference being the change in interval.
graph on left shows value 3 at 2min granularity (interval set to auto)
grah on right has a value of 5(?) but what the x-axis o be in a d e.g. 01/06 (interval set to 1d)

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
    NA

  • Did you follow any online instructions? If so, what is the URL?
    No

basically I am trying work out why the value in right hand graph is not 3 and how to change the x-axis to a day view e.g. 01/06.
