I often find myself adding either concatonated strings or using a string formatter in my debug statements in log4net and log4j should I surround these debug statements with an "if debug" block to stop myself from wasting resources by processing these parameters even though the debug statement will not be printed out? I would assume that...
Simple really, does Log4j SyslogAppender support MDC and NDC in the sense that the output is structured data i.e. uses the structured data features of the protocol? Further, are there any limits on what can be put in the MDC and successfully appended to the log? ...
Hi, I have the following log4j config in my Grails 1.1 app log4j = { // Enable Hibernate SQL logging with param values trace 'org.hibernate.type' debug 'org.hibernate.SQL' debug 'com.mycompany' appenders { console name: 'stdout', layout: pattern(conversionPattern: '%d{dd-MM-yyyy HH:mm:ss,SSS} %5p %c{1} - ...
For those who are developing applications that are under PCI scope, where the guidance suggests that you should store your application logs on another tier, remoting to a syslog server elsewhere feels like a best practice. The question becomes, what should the PatternLayout look like that best enables folks to review their logs at least...
I'm used to working with the excellent log4net, and I assumed log4j is a direct port or ancestor. I'm looking for an equivalent to the useful Logger.DebugFormat() family of methods, and I can't find anything like it. Is there anything like that in log4j (or similar packages)? If not, why not? ...
does this requirement conform to the J2EE Standards? is there a easy way to implement this, log file gets generated by Log4J and in the end I will access the file system and email the whole file(s). can I access the file system? ...
I am using Log4J in my application for logging. Previously I was using debug call like: Option 1: logger.debug("some debug text"); but some links suggest that it is better to check isDebugEnabled() first, like: Option 2: boolean debugEnabled = logger.isDebugEnabled(); if (debugEnabled) { logger.debug("some debug text"); } So...
Whats the best way to add log4j logging to a jsp tag file.. I've got as far as importing the logger class.. <%@ tag import="org.apache.log4j.Logger" %> But having a bit of trouble initialising the logger object. <% Logger log = Logger.getLogger("xxx.xxx.xxx.xx"); %> Because I'm using a tag file with a .tag extension, what do I put ...
I have a log file that has the following appender added to it : logger.addAppender(new FileAppender(new PatternLayout(),"log.txt")); the thing is, each time I'm running my application, additional logging information gets appended to the same log file. What can I do to overwrite the file each time ? ...
Essentially I'm looking for something with the same behavior, configuration, logging levels as log4j, but with some of the missing functionality (e.g. formatted logging — see here and here for related SO threads.) Current nominees are slf4j and log5j. ...
Can custom appenders created for log4j (extending AppenderSkeleton) be used with new logback framework? I know that logback comes with its own set of appenders similar to log4j, but is this possible to re-use existing ones? How? ...
So, here's my problem: I have a message driven bean X and would like to make use of Logger in X's onMessage() method. Lets presume that I have a single instance of the bean running in my app server, hence, I would initialize log4j in ejbCreate(). This would mean I would have to do something like this: public void ejbCreate() { Pr...
I'm experiencing and issue with tomcat where if I try to deploy my code I get the following error: Stacktrace: org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:504) org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:375) org.apache.jasper.servlet.JspServlet.serv...
I have some jar files that will be distributed to clients that are using log4j for logging. My question is should I include a log4j.xml configuration in the jar file or have the client provide one if they want logging? My feeling is to leave the log4j.xml configuration file out of the client jars, since the apache jar files all come wi...
Is there a way to create a log4j Logger at runtime that will gather logging messages into a buffer? I currently have a class that logs a number of events. For a remote application that needs to monitor the logged events, I'd like to just swap in a logger that logs to a buffer and then retrieve the buffer, rather than refactor the class...
In log4j, is there a way to have logger.error("") and logger.debug("") include different output layouts? I'd like errors to include method names and line numbers, both of which slow down application performance. EDIT: After adding apache-log4j-extras, the following config file works. <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE...
I can't find any reference to what versions of Windows the log4j NTEventLogAppender is supported on. I am specifically interested in whether it works on Windows Server 2008. ...
We have built a web application that accepts SOAP messages, does some processing, calls out to another web service, massages the response and sendd it back to the original caller. We'd like to log, in a single line, the different execution times for these different steps. We use log4j with the JBossWS stack. In other words, we'd like th...
Hi, Right now we are using a customized logger method for our application but now we have a stand alone code for which we need to write to a separate log file. We have little idea about log4j. I just want to know where to change properties if any so that i don't disturb the existing logger application as well as we write our logs into...
Let me preface this question by saying I've exhausted Google, or at least what I've been trying to search for. "log4j threshold", "log4j threshold category", "log4j appender threshold category", etc. But I really don't understand the results I'm getting back from Google. This is the full configuration I've been given. I can't figure...
