                                                                     io.grpc.MethodDescriptor<?,?> methodDescriptor,

getTags in interface GRpcMetricsTagsContributor

addTags

public java.lang.Iterable<io.micrometer.core.instrument.Tag> addTags(ReqT request,
                                                                     io.grpc.MethodDescriptor<?,?> methodDescriptor,
                                                                     io.grpc.Attributes attributes,
                                                                     io.micrometer.core.instrument.Tags existingTags)

Contribute tags when receiving the request message. For streaming calls, this method is invoked several times (once per message). The implementation should NOT concatenate existing tags with newly produced tags. It's supposed to produce new tags or accumulate existing tag's value.

Parameters:

request - current request message

methodDescriptor -

attributes -

existingTags - currently accumulated tags

Returns:

new tags

getTags

@Deprecated
public java.lang.Iterable<io.micrometer.core.instrument.Tag> getTags(ReqT request,
                                                                     io.grpc.MethodDescriptor<?,?> methodDescriptor,
                                                                     io.grpc.Attributes attributes)

Deprecated.

Prefer overriding addTags(Object, MethodDescriptor, Attributes, Tags) if you want to get a hold of already added tags(for streaming calls) and accumulate tag's value.
