Feature request: allow displaying all namespaces

In some cases, it may be useful to visualize network traffic in all namespaces at the same time. Relevant Slack discussion here.

This would be super helpful to me when looking for dropped packets when running in Audit mode.

[mattcharlton]

We've just moved to separate namespaces for our apps from a singular apps namespace.

This would allow us to see dropped packets and adjust policies much easier.

[Exeteres]

I think this is a vital feature for analyzing traffic between namespaces. I'm surprised it still doesn't exist. It would also be convenient to select several namespaces and view them in a single boundary.

Not only would it be useful, it would be cool.

It would be cool to see a graph of all namespaces.

Any updates?

[boomer41]

Would like to see that, too!

[LostPoE]

Is this feature on the roadmap?

[R-Studio]

Any updates?

For people being impacted by this not being able through the GUI, the CLI does allow for this:

#setting up a connection to hubble:
cilium hubble port-forward& 

# Observing the flows filtering on traffic that would be dropped 
hubble observe -A --verdict DROPPED -f 

You will need access to the backends to see this and both CLI tools installed (cilium & hubble)

Still it seems reasonable to have this as an option inside the GUI.

This feature is available in enterprise version.

Bump

[R-Studio]

Until this feature is available, we developed the hubble observer (CLI & Grafana Dashboard).

Just removing the value of the query parameter namespace in the URL works for me.

Example: https://hubble-ui.example.com/?namespace=default -> https://hubble-ui.example.com/?namespace=

Wait so its just a simple ui change if it actually works already?

[especially-relative]

It does work, technically. It is good for getting a cluster view of the traffic flow at the bottom. I use the tool exclusively for troubleshooting network policies currently.

Due to the layout engine the graphical display is unreadable. The sharp corners and overlapping edges are impossible to follow beyond the most simple of namespaces. Just compare the Hubble layout engine to something like Kiali. Already an open issue but viewing all namespaces makes it that much more apparent.
