I hope the subject is clear enough.
A bit more explanation of the question here.
The use case is like, multiple queries are defined for traffic on different nodes, and a compound metrics is needed for the sum of all the traffic metrics.
In other use cases, it could go beyond just sum up. And what’s to be shown in the graph is just ONE metrics, not all the original queries.
Is this use case supported by Grafana, instead of some code running outside?
Could anyone enlighten me?
