In the http rule, specifically match HTTP non-probe requests. #85

Open dmaze opened 4 years ago

Description

In the Istio rule object collecting HTTP metrics, add a match: clause that limits the rule to (a) only HTTP or gRPC requests, (b) not kube-probe requests, and (c) not Prometheus requests.

Additional context

This matches a similar match expression in the standard Istio Prometheus handler (see also istio/istio#12251). Without this, we see inbound request metrics from health checks, and outbound HTTP request metrics for background non-HTTP activity.
