Trace Header Form For Free

The HTTP X-Request-ID request header is an optional and unofficial HTTP header, used to trace individual HTTP requests from the client to the server and back again. It allows the client and server to correlate each HTTP request.

The first line of trace data is a trace header that identifies the trace and shows the current application ID, the current function, and the current screen.

The traceparent header Identifies the request in a tracing system, describing the position of the incoming request in its trace graph in a portable, fixed-length format. format = version ?-? trace-id ?-? parent-id ?-? trace-flags e.g. ?00?0af7651916cd43dd8448eb211c80319c-b9c7c989f97918e1?01?

HTTP headers let the client and the server pass additional information with an HTTP request or response. An HTTP header consists of its case-insensitive name followed by a colon ( : ), then by its value. Whitespace before the value is ignored.

The traceparent field version (8-bit): trace context version that the system has adopted. The current is 00 . trace-id (16-byte array): the ID of the whole trace. It's used to identify a distributed trace globally through a system.

If the traceparent HTTP header is not available then, you can set it by using the set-header policy of API Management policies. The set-header policy is used to assigns a value to an existing response and/or request header or adds a new response and/or request header.

The traceparent request header represents the incoming request in a tracing system in a common format, understood by all vendors. Here's an example of a traceparent header. For example, say a client and server in a system use different tracing vendors: Congo and Rojo.
