Remote sensors provide information about the remote calls made in an application. These sensors enable tracking of the remote calls and combing interactions between JVMs in a single trace. There are two types of remote sensors: server and client. Client-side remote sensor start a new tracing span before making an outgoing request and propagate the new span identification along with that request. Server-side implementations first extract a span identification from an incoming request and continuing or starting a trace from that point. Server ones are dealing with server-side requests, while client ones are capturing the client-side requests. Note that in remote communication one JVM can usually stand as both server (receiving requests) and client (making requests to another JVM/component).
