Recommendation for Tomcat web statistics program (AKA log analyzer)
?
I tried to find decent free web statistics program for Tomcat. (AKA Log
Analyzer).
I'm running standalone Tomcat (without Apache) on Linux.
I would prefer Java solution, but perl/c++/python might be ok.
I googled for 2 hours but I haven't found any Java solution.
Any recommendation?
I know about AwStats. Is anything other worth trying?
I'm sorry about previous post about the same issue which wasn't in
separate thread.
Thank you in advance for your answer.

yeah, strange, I've installed a fresh new tomcat, changed the port to
8180 and droped the webapp. Over night it stoped.
Try again :-)

Great, for me it might have sense to post official announcement here.
I hope announcement posts are not against the mailing list rules.
I hope I will find time to help you test it.

Glad you asked :-) In fact I've built some of such monitoring systems
over the years. I was always surprised, that there is no default
monitoring toolkit in the java world. I don't mean logging, logging is
simple. But to log something, you first have to produce the data, and
besides JVM Monitoring data from BEA's jrockit there isn't much out
there for production systems. So I decided to write one. You may be
the first to try it :-)
I've put a little demo under:
http://anotheria.net:8180/moskitodemo/
It's pretty simple, one monitored servlet, klick on the "make a
request" link (as often as you wish of course). On each click it will
sleep some time (emulating working) or throw an exception (emulating
error condition). You can view the stats for 1,5,15 minutes, 1 hour, 1
day or since start of the server (or whatever interval the servlet
designer configured).
A note on the stats generation: The stats are interval stats. That
means, that the 5 minute value isn't the value of the last 5 minutes,
but the value of the last 5 minutes interval update. To illustrate
this, following example:
The server is started at 12:00. You are checking at 12:03 the 5 minute
stats. What will you see? Nothing, since no 5 minute intervals are
completed yet.
If you'll check again at 12:07 you will see the stats gathered between
12:00 and 12:05. After 12:10 you will see the stats between 12:05 and
12:10. And so on. This is imho the only way to generate comparable
stats. If your server is slow today, you want to compare a 5 minute
value to the one from yesterday, not a 3 minute value to 5 minute
value and such.
However, enough said. Try it out, tell me what you think :-)
regards
Leon
P.S. Moskito is open source. I'm creating a downloadable distribution
right now, which will contain the core system, logging add-on for
log4j. Addon for servlet support. DemoApps and demo webapp (the one
you see). And the source code. The download page will be available
tomorrow :-)

In fact I might become interested in those information.
Average/max duration of time for each servlet/JSP.
Is it possible to get those information?

It seems to me that you are more interested in Loggers (classes which
does generate log files) than their representation.
I understand you, me, as developer should be also more interested in those.

In fact, I've just started my server and Awstats shows me who is calling
what on my server. It could take less memory, I don't like because it
use CGI (potential security issues?) but it works :), and it is usable.
At some point I might be more interested in "what the f*ck is my server
doing".
(for example : the response is slow).
Off course I might write my own loggers and trace duration time, but it
might be good idea to ask:
Is there any generic tool to use to find out "what the f*ck is my server
doing"?

No, I mean things like number of request for each servlet, total
number of time this servlet spent processing, number of errors, avg
request duration for last 5m,15m,1h,1d,1week... whatever.

you can always write a script which is getting the data and graphing
it... The problem is to collect the data :-)

Ok, I see, you are more interested in "who's calling what on my
server" and less in "what the f*ck is my server doing".

Hi Leon,
Live load statistics might mean also "memory and processor usage of the
server".
I will understand your question as : "do you want live or croned program?"
Since web stat program could be live or cached (using cron on Linux).
It doesn't matter at this moment to me is the program "live" or "cron".
I succeded to run Awstats using CGI and it is good, but there are some
things which I don't like.
So, if anybody have some other recommandation I would like to take a look.

do you want a log analyzer or live load statistics?
