Log to other file then srv.log

Hi,

Is it possible to log to other(s) file then srv.log

Like one file per app.

Sure, but you'll have to write the logging functionality yourself. I
have an eventlogger component in my server that gets the log file name
from the package properties and creates a log file for each package. You
could do Server, Package, Component or whatever you choose, but you will
have to write code to do it. In fact I recommend that you do NOT write
application messages to the srv.log file.

regards,
Bill

Take a look at Log4J, from the Apache project.  It provides a framework for
logging that could do most of the work for you.

Does it redirect standard out as well?

It can.  I wrote a bunch of output handlers that write to standard out,
special log files, and the message service.  Total time coding, about 2
hours.

If you want the samples, let me know.

Since we are on logging, let me throw this out.  Many operating systems use
buffered I/Os.  In the event of a Jag crash, the last line inside of the
srv.log may not actually be the last thing that executed.  Throw in Jaguar's
multi-threading issues, and you see logging lines interwooven among a number
of components, further complicating the issue.

The _best_ approach for logging is to use a database and a component that
transactionally writes out to a table(s) in the database.  In this way, you
tend to have more peace of mind that _everything_ that was queued to be
logged will indeed show up.

Giving credit where credit is due, Dave W. first explained this to me many,
many months back.

my $0.02 worth... or should I say Dave's :-)

Attached are the samples of code that I was talking about earlier.  There
are two appenders here.  One writes directly to the Jaguar Log, the other to
the Jaguar Message Service.  I also included a service component that sets
the entire logging process up when the server starts.

Please note that this code is distributed AS IS.  It's a sample only.


And, in response to Jason's post:

Yeah, I wrote an appender to solve that exact problem.  The other issue is
that the appender consumes I/O time to do the database write, so it still
slows down the application by logging.

The solution is complex.  What I recommend is that you perform an
'immediate' log to write any urgent or error messages directly to disk or
DB.  All other messages (warnings, debug, etc.) can be written to the
message service, which will the do asynchronous I/O.  So, the software won't
be slowed down by writing information you might need.

I understand the context but I think it's misapplied.  What you're
referrring to is a situation where the Jag server goes down, in which case a
buffered log will not show up.  In the case that you mention, if the Jag
server goes down, the transaction was very likely not completed causing the
write to the db to fail so effectively you have the same net effect, no
logging, but you have incurred signifcant overhead by applying all writes
through the db.  I agree that a db can handle concurrency issues likely much
better than a well thought out file concurrency algorithm but in this case
the marginal utility is non-existent.

I'd probably only be concerned if you were at the Cook off, had been out 
till 5 am the night before and was drinking before the cook off.

Oh wait - never mind.  I am worried about the response now<g> 

Mark

My server keeps dieing on me and the log never provides any clues (no PB
application errors, nothing).  The last line is the system tracing line that
says how long a component call lasted (TRACE: package/component/method: 0 ms
205 bytes in, 141 bytes out ([email protected])).

Could this buffered I/O be the reason why I never get anything more helpful
to figure out why it died?  Is there anyway to tell the O/S to not use
buffered I/O?  Rewritting my components to write to a database file isn't
really an option at this point (it's live) and from other posts, it doesn't
sound like that will help anyway...

Any other way to get more clues?  Can I turn on other kinds of tracing??

Thanks,

Daniel

Having been to several DC Chili Cookoffs myself, I would only be concerned
if I had to sit next to him the next day...

;>(

If you ever get the chance to go to the Cookoff, go.  It's awesome.

I so did NOT need to be reminded of the Chili cookoff... some days, I really
miss DC.  :-)  (But definitely not the day after... especially next to
Carson!  ;-) )

You actually remember 14 hours of drinking? <g>

Mark

My vote is that his watch probably stopped or got broken somehow.  After his
recovery, he knows that he partied for _at least_ 14 hours since that was
when his watch stopped.  Kinda like when the electric goes off and all the
digital clocks are reset to 12:00 :-)
