问题 Is it possible? I have found solution for Visual Studio Print n levels of callstack? 回答1: To print a backtrace at runtime programmatically, you can use this function: #import <execinfo.h> void PrintBacktrace ( void ) { void *callstack[128]; int frameCount = backtrace(callstack, 128); char **frameStrings = backtrace_symbols(callstack, frameCount); if ( frameStrings != NULL ) { // Start with frame 1 because frame 0 is PrintBacktrace() for ( int i = 1; i < frameCount; i++ ) { printf("%s\n",

问题 I use Jboss 6 and my static Logger logger = Logger.getLogger(Foo.class); displays nothing Tried adding log4 to my project, removing it, placing a log4j file on my main/resources folder, placing no log4j file and no results. Only System.Out seems to work, but it doesn't provide all the information I would like to see I even see Hibernate log working but not mine What am I missing? 回答1: Turns out my logging does work. Hibernate logging is controlled by the jboss logging settings. My logging

问题 I need to stop CXF from logging the binary data of attachments in a MultipartBody object (which is being thrown out by the AbstractLoggingInterceptor in the Outbound Message). When I add my LoggingInInterceptor , I am setting setShowBinaryData to false, but this doesn't seem to stop binary data within a multipart message from being logged. I am unsure whether I need to create a custom loggingInInterceptor, or whether there is a way of configuring the existing interceptors to truncate any

问题 I want to declare identifiers for scopes which will be used to automatically populate a field of any logging statements within the innermost scope. They will usually, but not always (e.g. lambdas, blocks introduced with {} ), match the "name" of the enclosing block. Usage would look something like this: namespace app { LOG_CONTEXT( "app" ); class Connector { LOG_CONTEXT( "Connector" ); void send( const std::string & msg ) { LOG_CONTEXT( "send()" ); LOG_TRACE( msg ); } }; } // namespace app //

问题 In WSO2 ESB, What does it show exactly the wso2-esb-trace.log file?, When might it be useful? And, What the different with other typical logs files in WSO2 ESB? For example, with wso2-esb-service.log or wso2-esb-error.log 回答1: It offers you a way to monitor a mediation execution : go to the web console, enable tracing on a sequence or a proxy service, execute this mediation (send a message to the proxy for exemple) and look at "mediation tracer" or edit wso2-esb-trace.log to gain details

问题 The tool (in this repo) comprises 3 classes (given below). The problem is how to make my ParaTracer.Logger class visible in every class I instrument (such as java.util.Random shown below). The statement cp.importPackage( "ParaTracer.Logger"); doesn't seem to work and I am getting this error: java.lang.NoClassDefFoundError: ParaTracer/Logger at java.util.Random.nextLong(Random.java) I tried dynamically loading the Logger class inside every instrumented class. But it seems I was using Class

问题 These are the Hadoop Logging Message I was trying to surpress 11/10/17 19:42:23 INFO mapred.MapTask: (EQUATOR) 0 kvi 26214396(104857584) 11/10/17 19:42:23 INFO mapred.MapTask: mapreduce.task.io.sort.mb: 100 11/10/17 19:42:23 INFO mapred.MapTask: soft limit at 83886080 11/10/17 19:42:23 INFO mapred.MapTask: bufstart = 0; bufvoid = 104857600 11/10/17 19:42:23 INFO mapred.MapTask: kvstart = 26214396; length = 6553600 I suppose they are configured by logg 4j.properties under the conf directory

问题 The documentation on Logback logging separation indicates that I can use context selectors to create different logging configurations on the same JVM. Somehow a context selector will allow me to call LoggerFactory.getLogger(Foo.class) and, based upon the context, I will get a differently configured logger. Unfortunately the examples only deal with JNDI in the context of a specially configured web server such as Tomcat or Jetty. I want to know how I can practically use a context selector

问题 Is it possible to get the full URLs in the logs of a Rails application? Currently I'm getting something like: Started GET "/" for 127.0.0.1 at 2011-08-27 13:13:10 +0200 but I need to get: Started GET "http://localhost:3000/" for 127.0.0.1 at 2011-08-27 13:13:10 +0200 because this is an app where the domains are important. 回答1: As of Rails 3.2.12, instead of monkey-patching before_dispatch or call_app, there is now a method that receives the request and returns the Started GET "/session/new"
