Apache Sling Logging Writer Configuration

Question

Hi,
I'm having an issue where my custom log writer configuration is not being picked up and used by CQ5 sometimes.  I've created a custom error log writer based on the example provided at http://helpx.adobe.com/cq/kb/HowToRotateRequestAndAccessLog.html which I've installed on an author, replicated it to the publishers, and all seemed ok and working correctly.  The settings are:
Log File: ../logs/error.log
Number of Log Files: 5
Log File Threshold: 200MB
After installing this, the error logs rotated at 200MB resulting in error.log.0, error.log.1 etc as expected.
However after rebuilds on the machines, this configuration was overwritten (as expected).  So I've installed and replicated the package again, but now the configuration is not taking effect.  I'm using the exact same config package as I was previously, but the logs don't seem to be rotating at all now (not even daily).  I've deleted the config from the Felix console on all authors and publishers, reinstalled on the authors, replicated to the publishers, then restarted the CQ5 service on all machines, but it's still not working.
So I have a couple of questions about this:
Is there somewhere else in CQ5 that might be overriding these log writer config settings?
Is ../logs/error.log correct for the standard log file location?  A note in step 3 of Creating Your Own Loggers and Writers on http://dev.day.com/docs/en/cq/current/deploying/configure_logging.html states:
Log writer paths are relative to the crx-quickstart/launchpad location.
Therefore, a log file specified as logs/thelog.log writes to crx-quickstart/launchpad/logs/thelog.log.
To write to the folder crx-quickstart/logs the path must be prefixed with ../ (as../logs/thelog.log).
So a log file specified as ../logs/thelog.log writes to crx-quickstart/logs/thelog.log.
     The configs in the log rotation example also use ../logs.  However when looking at the default/standard logging writer config, it uses logs/error.log.  Which one is correct?
Any help on what's going on here would be appreciated!!
Thanks,

Answer 1

Hi,
I am answering your last question and this one here only.
1. Log configuration can be override at project via creating config and overriding factory "org.apache.sling.commons.log.LogManager.factory.config-<identifier>" and writer (if required) "org.apache.sling.commons.log.LogManager.factory.writer-<identifier>". So plz check if you have configure log at project level. Now if you are not able to see then plz recheck you log configuration in felix console http://localhost:4502/system/console/slinglog here you can see entire log configuration for CQ system.
2. both will work but the location will change
     i. CQ 5.5 - log file located under "crx-quickstart" ../logs/<filename>.log will create under this
     ii. CQ 5.4 - logs creates under "crx-quickstart\logs" also under "crx-quickstart\launchpad\logs" so if you select ../logs/ it will go under "crx-quickstart\logs" only but you can change wherever you want to store. Again you can see this configuration info at http://localhost:4502/system/console/slinglog
3. You can also customize you log via creating at project level and assigning the "identifire" (with all other configure parameters) for more information you can refer http://sling.apache.org/site/logging.html apart from earlier share links.
I hope above will help you to proceed. Please let me know for more information.
Thanks,
