gRPC statistics filter configuration

• bool emit_filter_state = 1

  If true, the filter maintains a filter state object with the request and response message counts.

• oneof per_method_stat_specifier

  • api.v2.core.GrpcMethodList individual_method_stats_allowlist = 2

    If set, specifies an allowlist of service/methods that will have individual stats emitted for them. Any call that does not match the allowlist will be counted in a stat with no method specifier: `cluster.<name>.grpc.*`.

  • google.protobuf.BoolValue stats_for_all_methods = 3

    If set to true, emit stats for all service/method names. If set to false, emit stats for all service/message types to the same stats without including the service/method in the name, with prefix `cluster.<name>.grpc`. This can be useful if service/method granularity is not needed, or if each cluster only receives a single method. .. attention:: This option is only safe if all clients are trusted. If this option is enabled with untrusted clients, the clients could cause unbounded growth in the number of stats in Envoy, using unbounded memory and potentially slowing down stats pipelines. .. attention:: If neither `individual_method_stats_allowlist` nor `stats_for_all_methods` is set, the behavior will default to `stats_for_all_methods=false`.

gRPC statistics filter state object in protobuf form.

• uint64 request_message_count = 1

  Count of request messages in the request stream.

• uint64 response_message_count = 2

  Count of response messages in the response stream.
