Within the mesh I have locked down egress with REGISTRY_ONLY setting in the istio configmap and verified egress traffic is halted, all services that require DB and other external services turn red.
I then apply my ServiceEntries for egress and all the apps start working again, however kiali shows traffic as passthroughcluster in one service node on the graph.
I expect to see one node on the right side of the graph for each SE being used, and I did have it showing correctly at one point but I also had an egress gateway configured at that time. I do not now.
Has anyone seen this issue before? Do you need an egres gateway setup for serviceentries to show up on the kiali graph?
