Chainsaw Tab identifier
Hello, I'm trying to figure out what things I need to place in my Tab identifier field to filter out my applications. I'm using log4j v 1.2.13 and chainsaw v2. I have two applications running on the same server and both are using a socketHubAppender on different ports. I don't have any location info so the default "PROP.hostName - PROP.application" only separates by hostname and since I'm running two apps on the same server I get both logs dumped to the same tab. I've tried adding PROP.remoteSourceInfo (since that is a column in the logs that shows up and has the port number listed) and that property appears to return nothing. It's my understanding that the location info does not work in log4j 1.2.X. So my question is two fold. Is there some reference that I can look at that will tell me what properties are available, and can someone tell me how I would go about doing this? I see in the comments for LoggingEventFieldResolver the following field are available but nothing here seems like it will work for me. Plus there seems to be no explanation of what keyName is in PROP.keyName. * Field NameField value (String representationReturn type * LOGGERcategory name (logger)String * LEVEL level Level * CLASS locationInformation's class name String * FILE locationInformation's file name String * LINE locationInformation's line number String * METHODlocationInformation's method name String * MSG message Object * NDC NDC String * EXCEPTION throwable string representation ThrowableInformation * TIMESTAMP timestamp Long * THREAD threadString * PROP.keyName entry in the Property hashtable String * mapped to the key [keyName] Any help would be appreciated.

Re: Chainsaw Tab identifier
Thanks Scott that was very helpful (and fast). Am I missing the reference to what Prop keyNames are available? It would be nice to know what is available (who knows maybe I'll find something i didn't know i couldn't live without). Even if it's just a matter of looking at the right javadocs that's enough. I'd just like to be able to tinker on my own. Thanks for all your hard work. Chainsaw is pretty cool.

Re: Chainsaw Tab identifier
Sorry Scott I had not tried your instructions before I replied last time. I can get PROP.log4j.remoteSourceInfo to show up in my tab identifier but PROP.application does not seem to work (which to be honest is much closer to what I want). I've seen that there is an issue with the serialized object translation from the 1.2.X branch to the 1.3 based chainsaw v2 download, and I don't receive Class, Method, File, or Line information in my logs. Is this possibly the reason PROP.application does not show up, or is there something else I have missed? Here is the log4j.properties snippet for my app. I've bounced my server container just to make sure it reloaded and PROP.application continues to return nothing in chainsaw log4j.properties sinppet (on server) log4j.appender.HUB=org.apache.log4j.net.SocketHubAppender log4j.appender.HUB.port=9005 log4j.appender.HUB.LocationInfo=true log4j.appender.HUB.Threshold=DEBUG log4j.appender.HUB.application=SES Test Tab identifier string PROP.application - PROP.log4j.remoteSourceInfo chainsaw.xml ?xml version="1.0" encoding="UTF-8" ?> http://jakarta.apache.org/log4j/"; debug="true"> class="org.apache.log4j.net.SocketHubReceiver"> Jason Tholstrup On Mar 3, 2008, at 11:42 AM, Scott Deboy wrote: Two things: 1.

Re: Chainsaw Tab identifier
I'm sure you get this a lot but after reading quite a few posts I am still kind of confused: The lineage between the 1.3 and 1.2 branches is very hazy. From what i can tell 1.3 is essentially dead and that 1.2 is the recommended version to use. As for chainsaw, should I be using the v2 that is available directly on apache's web site? This appears to be based on version 1.3 code if I read correctly. Should I instead be using version 1.2.15 and using the chainsaw client available from there as well as using log4j 1.2.15 on my appender side? I've seen posts mentioning getting the latest 1.2.15 version from svn to get the "right" version of chainsaw. Is that now current with the latest release or do I still need to tread into the waters of a nightly build? On the back porting effort, what is the status there? Is that completed and that is the purpose of 1.2.15? Is that just a partial back-port with more to come? Is that a partial back-port and that's the end of the road? And finally we have a third party app we were trying to get logging working under that is using 1.2.9. Could we safely drop in 1.2.15 and be able to configure our appenders as you describe (we have access to the log4j.properties file on the server)? Thanks for being patient and walking me through all of this. You've easily save me a couple of days of bumbling around trying to get this to work.

Btw, log4j 1.3 sockethubappender supported a 'buffersize' param which would forward the last X events to the connecting sockethubreceiver, but it doesn't look like that was back-ported to log4j 1.2.15.

Re: Chainsaw Tab identifier
Hey Scott,
Thanks so much for the help. I've started creating a custom version
of the SocketHubAppender which implements the buffer you mentioned
(Yanked the code from the 1.3 branch and it works like a charm.
Thanks for mentioning it).
I also tried to set the "application" property into this custom
Appender using the code from SocketAppender as a template. I am not
getting the application property to come across the wire, nor can I
seem to get any property to come across the wire. I get the
remoteSourceInfo, hostname, and log4jid to come across but I'm
guessing that is happening on the chainsaw side. From digging through
the 1.2 and 1.3 code bases I noticed that the LoggingEvent seems to
handle properties differently. The 1.2 code base uses the mdc to set
the property in and the 1.3 code base uses the properties map. Am I
running into another incompatibility issue between log4j 1.2.15 on the
server side and chainsaw (log4j 1.3 version) or am I completely
missing the point of how I set properties?
Code snippet from socketHubAppender where I set properties on the
logging event. I've debugged through here and verified that the
properties exist in the mdc on the LoggingEvent.
/**

event.getLocationInformation();
}
if (buffer != null) {
buffer.add(event);
}
if (application != null) {

event.setProperty("application", application);
}
// set property all the time name
event.setProperty("randomProp", "hello");

log4j 1.3 is abandoned - the useful bits were (mostly) backported to
log4j 1.2.15 with a few 'companion' downloads providing the non-core
functionality added to 1.3.
There are a few caveats:
- Chainsaw V2 trunk (built against log4j 1.2.15) has not yet been
released. Once it is released, location info will work again.
- The version of Chainsaw available via web start is based on log4j
1.3, so location info won't work
- The component, receivers and zeroconf 'companions' have not yet been
officially released - the 'extras' companion has been officially
released (meaning any not-yet-released companions need to be built
from
source..)
Since Chainsaw V2 built against log4j 1.2.15 (along with the receivers
and other companions) have yet to be officially released, it's a
pain to
build Chainsaw on the trunk (maven dependencies on snapshots...ug).
As for compatibility between log4j 1.2.15 (and Chainsaw V2) and prior
versions, Chainsaw V2 should work fine with log4j 1.2.9 (including
support for location info).
Everything we wanted to keep -should- already be backported to log4j
1.2.15 + companions..the sockethubappender buffer issue is one that
was
missed..
Once everything is released, it'll be a lot easier to build from
sources.

Re: Chainsaw Tab identifier
Yeah Scott I actually got the 1.2.15 branch of chainsaw built last
night. You guys have documented the build process pretty well so it
wasn't too bad. (I especially like the mac-app builder). I'm already
back porting the bufferSize stuff that you mentioned so the
application bit is no big deal. Once I've got this all flushed out
and working would you like me to send you the upgraded version of
SocketHubAppender? Any guide lines I'd need to follow to contribute
it back?

You're right, the properties you mentioned are generated on the

I'm not sure why properties aren't working, but you're probably
right -
changes to loggingevent's serialization of properties is different
between 1.2 and 1.3, and you're probably running into that issue.
To get location info (and properties) to work, you'll need to pull
Chainsaw from svn trunk and build it using maven. There are a
number of
dependencies, including the companions, all of which aren't yet
released, so it's a bit of a hassle.
Once you have Chainsaw from trunk and you're using log4j 1.2.15 on the
appender side, everything will work.
You don't -have- to add support for the application property
directly in
the sockethubappender (unless you want to) - you could wrap your
socketappender with a rewriteappender which specifies a
PropertyRewritePolicy. This will allow you to add properties through
the config file.
Hope that helps,
