Constructor Detail

HttpServerHandler

public HttpServerHandler(HttpExtractor extractor,
                         WebModulesContainer webModulesContainer,
                         java.util.List<com.microsoft.applicationinsights.internal.util.ThreadLocalCleaner> cleaners,
                         com.microsoft.applicationinsights.TelemetryClient telemetryClient)

Creates a new instance of HttpServerHandler

Parameters:

extractor - The HttpExtractor used to extract information from request and repsonse

webModulesContainer - The WebModulesContainer used to hold WebTelemetryModule

telemetryClient - The TelemetryClient used to send telemetry

Method Detail

handleStart

public RequestTelemetryContext handleStart(javax.servlet.ServletRequest request,
                                           javax.servlet.ServletResponse response)
                                    throws java.net.MalformedURLException

This method is used to instrument incoming request and initiate correlation with help of WebRequestTrackingTelemetryModule.onBeginRequest(ServletRequest, ServletResponse)

Parameters:

request - incoming Request

response - Response object

Returns:

RequestTelemetryContext that contains correlation information and metadata about request

Throws:

java.net.MalformedURLException

handleEnd

public void handleEnd(javax.servlet.ServletRequest request,
                      javax.servlet.ServletResponse response,
                      RequestTelemetryContext context)

This method is used to indicate request end instrumentation, complete correlation and record timing, response. Context object is needed as a parameter because in Async requests, handleEnd() can be called on separate thread then where handleStart() was called.

Parameters:

request - HttpRequest object

response - HttpResponse object

context - RequestTelemetryContext object

handleException

public void handleException(java.lang.Exception e)

This method is used to capture runtime exceptions while processing request

Parameters:

e - Exception occurred
