Subject Re: Help Log4j Chainsaw - VFSLogFilePatternReceiver Usage
Date Fri, 22 Jul 2011 17:31:42 GMT
Chainsaw can automatically build a Chainsaw config file from fileappender
entries in a log4j appender config file (both log4j.xml and log4j.properties
formats)...

By the way, I assume you can get sftp processing to work fine now as well,
since it looks like you just had incorrect slashes in your URL?

The code that parses the log4j.xml config is a little case sensitive, so
modify your appender to have the 'file' param lowercase and save it - I'll
commit a fix for this.  Chainsaw doesn't know what catalina base is, so you
should temporarily replace the catalina.base system property with a path:
    <param name="file" value="/path/to/logs/mylog.log" />

Then in Chainsaw:
1. use the file-load chainsaw configuration menu item
2. Choose the (default) Use fileappender entries from a log4j config file
3. Click 'open file' and browse to your log4j xml configuration file and
select it
4. Click the 'save configuration as' button and save this configuration with
a file name (it will generate an xml configuration file, so save with an
.xml extension)
5. Click the 'always start Chainsaw with this configuration' (if you'd like)

Chainsaw should parse the conversion pattern and create a
VFSLogFilePatternReceiver configuration that will parse the fields in your
log file.

Don't forget to un-do your temporary changes to your log4j xml config file.
This same process would work for remote config files, you would just need to
change the resulting fileURL in the chainsaw config file to be an sftp://
URL.

Hope that helps..

Scott
