Some graphs are cumulative by default #9

Open vladvisan opened 8 months ago

vladvisan commented 8 months ago

Some graphs in the dashboard seem to be cumulative/sum by default, which gives counter-intuitive results? Maybe changing the default behaviour would make the results more intuitive?

Can you be more precise and give us which graph is cumulative? As far as I know, for cumulative data like RSS memory for example, we are drawing the derivative sum, and not the sum directly.

Hi, there is an example at this link https://gricad-dashboards.univ-grenoble-alpes.fr/d/a92Zdkb7k/colmet-bigfoot-jobs-stats?orgId=1&from=1707492254000&to=1707597602000&var-Job_ID=1165396&var-Node=All

Job ID = 1165396 Start time = 2024-02-09 16:24:14 End time = 2024-02-10 21:40:02 Cluster= Bigfoot

The CPU Load, Write bytes/s and Read bytes/s graphs at least seem cumulative.

I was not able to find any examples on Dahu, all the jobs I looked at had all their graphs look non-cumulative:

Job ID = 24326258 Start time = 2024-01-31 14:48:14 End time = 2024-02-15 00:30:04 Cluster= Dahu
