Multiple servers writing to the same file
If I were to have a NAS and mount a folder on 2 different servers to a
folder on the NAS could I use log4php to write to the same file from
both servers?
The goal is to have 1 log file from 2 servers in a load balanced array.

If you're looking at the quickstart page on the log4php web site [1] then
there's a mistake in the example.
The 4th line of the XML configuration says:
<param name="file" value="myLog.log">
But it should be:
<param name="file" value="myLog.log" />
Found that recently. We'll correct it soon. Hope that helps.

Ivan

RE: Multiple servers writing to the same file

I am just working on the quick start, trying to get it implemented. I am
used to using log4j but this is my first time with this package.
I was able to get events logged to the apache log file now I am working
on the second example and it should be creating a myLog.log file but
nothing is happening and I see no errors in the logs.
It's probably something pretty basic, please help.
Thanks

That should work fine because the file is locked each time before
writing to it (exclusive lock).
I haven't tested this on a NAS setup, but I have tested it by having two
processes log continuously to the same log file on a local disk and this
works ok.
Let us know if you run into any problems.

I tested on Ubuntu and it works straight away. Is there any PHP
configuration that would specifically prevent this from working?

That's strange. I just tried it (windows) and it works fine.
Try specifying the full file path, just in case. Something like:
<param name="file" value="/home/user/myLog.log" />

Phew, that's sorted then. Magic quotes are evil, anyway. :)
Have fun with your project. And let us know if you have any other problems.

Ivan,
Thank for your help.
The problem was that magic quotes was turned on, on this machine.
This is something I had thought was changed when we upgraded to 5.3 several months ago.
I have disabled magic quotes and everything is now working as expected.
Regards,
Mike

Well that probably means that this is a configurator issue.
You know what... try configuring using a properties file. Create log4php.properties (or whatever) and put this in:
log4php.appender.default = LoggerAppenderFile log4php.appender.default.file = myLog.log log4php.rootLogger = DEBUG, default
Then configure using
Logger::configure('log4php.properties ');
This uses a different configurator and it might not have the same bug.
I may install gentoo to try and figure this out if I have the time.
Too bad PHP is not included on their live CD. Do you know any good quickstart tutorials? :-)
Regards,
Ivan

Re: Multiple servers writing to the same file
Posted by Ivan Habunek <iv...@gmail.com>.
Well that probably means that this is a configurator issue.
You know what... try configuring using a properties file. Create
log4php.properties (or whatever) and put this in:
log4php.appender.default = LoggerAppenderFile
log4php.appender.default.file = myLog.log
log4php.rootLogger = DEBUG, default
Then configure using
Logger::configure('log4php.properties ');
This uses a different configurator and it might not have the same bug.
I may install gentoo to try and figure this out if I have the time.
Too bad PHP is not included on their live CD. Do you know any good
quickstart tutorials? :-)

Ivan

RE: Multiple servers writing to the same file
Posted by Michael Sole <ms...@gold-mobile.com>.
I checked and it is installed but I knew that as I use it elsewhere.
Here is the feedback from the guys I have working on the issue (besides
myself):
I found it was reading the config file but if I queried it for current
loggers it had nothing. I tried both stable and trunk versions of
log4php along with several different examples. It is not even trying to
open a file for writing or making any syscalls that are having errors.
At this point someone will dig through the log4php code to try and
figure out whats going on.
I added logging to the append function and it wasn't even making it
there.
Like I said it works on Ubuntu so there is some weird interaction with
Gentoo.
Would suexec affect it in anyway?

Possible. Can you run "php -m" and see whether you have the libxml
extension loaded? I think that is the only prerrequisite...

Well, I'm really not sure what is wrong here. I haven't tested log4php
on gentoo, but it has been tested on ubuntu and debian.
If you're feeling adventurous, you can add some var_dumps or such to the
log4php source. The logging is being done in:
/src/main/php/appenders/LoggerAppenderFile.php
The function is append() on line 109.
Anything that prevents fopen/flock/fwrite from working would be a
problem. Not that any specific config option comes to mind.
E.g. try duping what is returned by flock() in line 111. If flock fails,
then the appender will stop logging without reporting an error.
Unfortunately, there's still a lot of potential silent failures in
log4php source. We're working on improving error reporting.

I think the failure is happening before that point. I doubt the function

Re: Multiple servers writing to the same file
Posted by Ivan Habunek <iv...@gmail.com>.
Well, I'm really not sure what is wrong here. I haven't tested log4php
on gentoo, but it has been tested on ubuntu and debian.
If you're feeling adventurous, you can add some var_dumps or such to the
log4php source. The logging is being done in:
/src/main/php/appenders/LoggerAppenderFile.php
The function is append() on line 109.
Anything that prevents fopen/flock/fwrite from working would be a
problem. Not that any specific config option comes to mind.
E.g. try duping what is returned by flock() in line 111. If flock fails,
then the appender will stop logging without reporting an error.
Unfortunately, there's still a lot of potential silent failures in
log4php source. We're working on improving error reporting.
Regards,
Ivan

Yeah I was already trying that:
<param name="file"
value="/vdomain/logtest.goldmobile.mobi/html/myLog.log" />
<!-- 2 -->
But no dice, its gentoo so there might be some weirdness with it.
I am going to ask my managed host for help and try it on an Ubuntu
machine.
Any other suggestions would be helpful.

Thanks.
I made the correction but still no luck. The file would be made in the
same folder as the script that calls it right?
I pastebined my code for reference http://pastebin.com/r9XVataM

That should work fine because the file is locked each time before
writing to it (exclusive lock).
I haven't tested this on a NAS setup, but I have tested it by having two
processes log continuously to the same log file on a local disk and this
works ok.
