Hi team, I am working on Kibana Dashboard trying to get a particular metric. for example, I have 3 kubernetes nodes and I am trying to create a dashboard with the Total of memory and CPU consumption, I am trying with lens, TVSB, and the classic Aggregation Based, I am not able to get the proper value of the Total Consumption, for example
I have the 3 nodes there, with the memory capacity, But I can't find the way to sum the 3 nodes to get the total capacity, is it possible to do?
Regards!

Hi @Sergio_Ferreyra Welcome to the Community.
Yes this is not super easy today.
You need to do a Series Agg : Sum across the Nodes
Today this is not supported in Lens, that is coming soon.
In TSVB
Example
Average of Metrics (example load.1m)
Series Agg : Sum
Group By : Terms : Node Name
This is saying Add the Average of the 1M Load across my nodes in for each Bucket.
Here an example :
Give it a Try...

Hi @stephenb Thanks ! good news if Lens will support this feature in the future, I will try now, the problem with the average is I am not sure why is doing this operation example (3.9+3.9+7.8)/3 =5.2, so it's showing the average value between the 3 nodes and not the total of the capacity of the cluster. I will try again anyway

Make sure that the Series Agg is **Sum** not Average.
That means Sum the 3 Individual Averages
And you have to do that Group By Terms then set to node Name

Good, I did the same and looks good, just a question , I am trying to get the CPU capacity, for example I have 4 kubernetes nodes in Digital Ocean with 2vcpu, so the total that DO shows me is 8.
Example
: 
I am using kubernetes.node.cpu.capacity.core field to get the values, example
Here the example
Do you know if I am using the proper field to get the values?
Regards!

I do not I am not an expert on K8s metrics but I am sure you can look it up... is that metricbeat if so you can look at what fields are exported and the definitions.

@stephenb yes, I read that documentation, thanks a lot!

you can take the Group By and Series Agg out and see the individuals nodes / values.... maybe something else is reporting

linking up what I think is a related enhancement that would bring this to lens formula - [[Lens] Formula: Define level of metric · Issue #94789 · elastic/kibana · GitHub](https://github.com/elastic/kibana/issues/94789)
you _can_ get at this number in formula but you need to be willing to visualize something like your node name. the series agg is the way to do it today!

@stephenb It's working well and better than the DO panel 😃.
thanks a lot!
