Fixes #3562 When a pod in one namespace sends traffic to a service which is the apex of a traffic split in another namespace, that traffic is not displayed in the `linkerd stat trafficsplit` output. This is because when we do a Prometheus query for traffic to the traffic split, we supply a Prometheus label selector to only select traffic sources in the namespace of the traffic split. Since any pod in any namespace can send traffic to the apex service of a traffic split, we must look at all possible sources of traffic, not just the ones in the same namespace. Before: ``` $ bin/linkerd stat ts NAME APEX LEAF WEIGHT SUCCESS RPS LATENCY_P50 LATENCY_P95 LATENCY_P99 webapp-split webapp webapp 900m - - - - - webapp-split webapp webapp-2 100m - - - - - ``` After: ``` $ bin/linkerd stat ts NAME APEX LEAF WEIGHT SUCCESS RPS LATENCY_P50 LATENCY_P95 LATENCY_P99 webapp-split webapp webapp 900m 80.00% 1.4rps 31ms 99ms 2530ms webapp-split webapp webapp-2 100m 60.00% 0.2rps 35ms 93ms 99ms ``` Signed-off-by: Alex Leong <alex@buoyant.io> |
