Extensions 2.0 - chart resolution

[stijn_bienkens]

Hi

We are currently building an extension and for some metrics we only query Prometheus with an interval of 5 minutes.

This works fine for the most part, except when trying to display these metrics on unified analysis pages as an area chart with a timeframe set to "last 7 hours" or less. In this case, the area chart contains gaps, because the resolution/interval is set to 1 or 3 minutes:

Expected (with a timeframe of 7 hours or less):

Chart config:

          - displayName: Test
            visualizationType: GRAPH_CHART
            graphChartConfig:
              metrics:
               - metricSelector: <metric key without transformations or expressions>
                 visualization:
                  seriesType: AREA
               - metricSelector: <metric key without transformations or expressions>
                 visualization:
                  seriesType: AREA
               - metricSelector: <metric key without transformations or expressions>
                 visualization:
                  seriesType: AREA
              defaultAggregation: AVG
              visualization:
                seriesType: AREA
                themeColor: DEFAULT
                showLegend: true
              stacked: true
              connectGaps: true

Using a rollup transformation doesn't work either, as this prevents the chart from being displayed when Dynatrace chooses a resolution that isn't compatible with the rollup interval based on the timeframe selector.

Is there an option to set a fixed resolution that I missed or is this currently not possible?

Thank you.

In Data Explorer, set resolution for the graph  to 5 minutes, and it should be OK.

[stijn_bienkens]

Yes, this works in data explorer but how can we achieve the same thing in "unified analysis pages"?

[DominikKinal]

"connectGaps" should help unless you send zeros in data as well. If not, then I think you can use bar chart instead. There is no option to set minimal resolution.

"connect gaps" - it should work as well

[stijn_bienkens]

Unfortunately, it doesn't work the "gaps" are connected, but it still looks like the first screenshot in my initial post.

Just a quick question, why not pull metrics every 1 or 3 min?

Another option - contribute/fork in PowerUps plugin for UI override:

Hi @stijn_bienkens, were you able to find a solution for your use case?
