Hello
Is it possible in the new Dashboard app to show a chart with a trendline that represents the sum of multiple interfaces In (or Out) Bit Rate parameter, for example? How do you advise this to be done?
Thank you.
Best regards

Might be difficult. To my knowledge:
The current trend graph in Dashboards allows you to display multiple metrics like bit rates from multiple interfaces in overlay, but does not support a stacked presentation yet.
You can build an aggregation rule on the view level and define a new metric there. This has the advantage that the sum would be calculated server-side continuously, and you can alarm and perform trending on that. But I believe you then will not be able to easily access that new metric in the Dashboards to display it there in a graph.
The GQI definitely also allows you already to aggregate on multiple interfaces and do things like sum, average, min, max, percentiles, etc. But that will show you the current aggregated value on your dashboard, and not a trend graph showing that value over time.
Other people might have some further perspectives on this. Because it is a common use case and we should ensure that we can support this easily.
Most definitely, and could not agree more. And to just confirm: for your use cases, you are mostly focused on the graphical presentation (i.e. to stack the data graphically). For your use cases it is not required to aggregate the data continuously and to be able to alarm and store the aggregated value as a separate time series in the database. Correct?
Hi Ben,
Thank you for your thoughts on this.
I would like to hear more about it from the Community, to know how is this kind of subject being addressed using Dataminer in the present, since it is a major requirement for me nowadays. (for example, show stacked graphs with data from multiple interfaces from different sources / elements sometimes)
Besides Dashboards app, is there any advice on how to address this challenge and present this kind of information in Dataminer? What is the best way to present to a user a stacked graph with the required interfaces bit rate information? (from multiple sources / elements)
Can we do it using “Trend Groups”, for example?
Thank you.
