public final class VirtualCluster extends com.google.protobuf.GeneratedMessage implements VirtualClusterOrBuilder
 A virtual cluster is a way of specifying a regex matching rule against
 certain important endpoints such that statistics are generated explicitly for
 the matched requests. The reason this is useful is that when doing
 prefix/path matching Envoy does not always know what the application
 considers to be an endpoint. Thus, it’s impossible for Envoy to generically
 emit per endpoint statistics. However, often systems have highly critical
 endpoints that they wish to get “perfect” statistics on. Virtual cluster
 statistics are perfect in the sense that they are emitted on the downstream
 side such that they include network level failures.

 Documentation for :ref:`virtual cluster statistics <config_http_filters_router_vcluster_stats>`.

 .. note::

 Virtual clusters are a useful tool, but we do not recommend setting up a virtual cluster for
 every application endpoint. This is both not easily maintainable and as well the matching and
 statistics output are not free.
