Help with reloading a servlet for log4j logging.
Hi, I am initializing Log4J system using an init servlet, which is loaded on start-up (servlet name is Log4JInitServlet). In web.xml I am pointing to the log4j.properties file using the param tag. Problem Now suppose I change some properties in log4j.properties file. (change the log level for example). I want to reload this file with the changed properties and restart log4j system with these new properties. Question Can I re-load the new properties file (and consequently the log4j system) by reloading the initservlet (LogJInitServlet)? Something similar to reloading an entire webcontext using http://localhost/manager?reload=myLog4JApp. I don't want to restart tomcat to restart the logging system. Can this be done in tomcat? I am using tomcat 4.x version, on win32/linux systems. Thanks a lot in advance, Subhro.

Parsing Log4J log file.
Hi,
Given :
I am using Log4J along with AspectJ for logging.
The Conversion pattern I am using in log4j is as follows. (This is just
an example)
%d{ABSOLUTE} %5p %X{JSESSIONID} %c{1}:%L - %m%n
In a Servlet filter I am setting the JSESSIONID in a MDC.
So finally my logs are something like this:

Each log statement has the session id along with it.
Problem:
I want a log viewer. A graph plotted for each SET of session ids. So the
user will enter some thing like 16CB951ED8ADBB1262AC21944AD94AF8 as
input(to start with). My viewer will parse all the entries in the log
file for the particular sessionid entered by the user. It will then plot
a graph with the names of methods/classes. So basically the idea is to
get a picture of all the method calls that got executed. The viewer need
not process log files in real time.
So I am looking for some API for parsing Log4J logs. I know of chainsaw.
But I don't know if this can parse existing log files and give some sort
of plot of all the method calls.
Possible Solution:
Write a perl script to parse the log files. Feed this data in some graph
plotter. Probably use some cross platform GUI toolkit for some
flamboyancy (wxWindows/Swing). This is required to be running on
Linux/Win32 systems. I am not very accommodating with Swing. But if it
can fix the problem, I will be more than happy.
Alternatively I can use Perl:GD wrapper to generate png images on the
fly and display it on a browser. This will be very good.
Please suggest something on this regard.
Thanks a lot in advance.
Subhro
