some questions regarding chainsaw
Hi ! we are testing chainsaw as a solution for our real time log monitoring environment. i have been playing with the application for a few days and i have a few questions: 1) after configuring a reciever - is there a way to save the configuration so that i will have it ready the next time i open chainsaw ? 2) was chainsaw tested under heavy load of logging events ? 3) once i have defined a new tab (either by configuring a reciever or by creating a custom expression logpanel) how can i remove the tab ? close it ? thanks a lot, Shai Simchi Invoke Solutions Ltd. +972-3-5756828 (ext. 206) +972-66-227746 (mobile) +972-3-5756829 (Fax) mailto:[EMAIL PROTECTED] www.invoke.com
RE: What is the significance of rootCategory in property file.
Hi, The root category is not required in configuration files. It is implicitly created for you whether you specify details for it or not. Most people specify it in order to set the basic level of logging for their system such that 3rd party libraries using log4j aren't logging at too verbose a level. I can't help much with India-specific book purchase questions, besides the obvious avenues I'm sure you're already explored, such as Amazon and eBay, that ship internationally.

I have a web application under tomcat. This web application is integrated from different modules (my project specific) and each module has its own log4j property(with different names) file.

RE: Displaying custom log level in Chainsaw v2
You would need to write a custom Level class and XmlDecoder would need to support a parameter allowing you to specify a custom Level implementation. This change would display the custom level in Chainsaw (if you used text and not icons), but expressions like LEVEL MYCUSTOMLEVEL won't work (they'll all evaluate to DEBUG). I haven't looked into how much work it would be to support this.

RE: Displaying custom log level in Chainsaw v2
We should adapt Level to use some of the enum techniques used in o.a.j.commons.lang.Enum and com.dautelle.util.Enum from JADE. This is listed in my todo list as a priority item.

output to multiple file
I am using a properties file for log4j. I am trying to have different output files for different packages (depending on the way the logger is initialized) Can any one please show an example how to do this.
RE: how to log to different files
Would it be possible to see the full config file and code snipet to see
exactly what is going on. Or try mine and see if it works.

Subject: how to log to different files
Hi
I wish to have output from classes to go into a log file and some
other classes (from the same packages) into another log file. I have
the following log4j.properties configuration but it doesn't work.
From the config, there are 4 fours that I wish to go into 'searchfile'
and all the other classes to log to 'file'.
What this produces is both files (searchfile and file) are created and
contains exactly the same logs. All logs (including those from the 4
classes) goes into both the files.
This is what I have in my Java files.
static Logger logger = Logger.getLogger(CatCrawler.class);
PropertyConfigurator.configure(path_to_log4j.properties_file);

Re: What is the significance of rootCategory in property file.
Hi Yoav, Thanks alot for the information. Can I have any number of log4j properties files under a single web application ? If so, where to put these properties files under tomcat ? Are there any guidelines that I have to follow if there are many lo4j properties under a single web app ? Any help in this regard will be very useful for me.

Running the same package in different JVM with the same log4j configuration
Hi, I running one the same server multiple JVM machine which are running the same java package. The log4j configuration file location is in a property file in my logger framework package which is also running in each JVM of course. I using a FileAppender to as log trace. As a File can't be open twice, only one JVM can't write into the file. The problem also occurred for all Appender which extend the FileAppender. As work around I wrote a new FileAppender which use a System property to post fix the file name. So, I can launch different JVM with different System property and then avoid the concurency problem on a non-sharable ressource. I would be nice to have this feature in a future release or have a way or it already exists a way (which I ignore) to avoid this problem. Regards Dominique
Re: Using log4j for writing a library...
I am writing a Java based library for which I am using the log4j package (version 1.2.8) a) Are there any special things we need to worry about configuration. Since you are writing a library, you have to be aware of what log4j does by default if nobody does any configuration at all.
