Use Sawmill to analyze Wowza Streaming Engine logs

The Sawmill universal log file analysis tool supports Wowza Streaming Engine™ media server software log files.

Note: The instructions in this article apply to Wowza Streaming Engine and later. For version 4.8.5 and earlier, see Use Sawmill to analyze Wowza Streaming Engine logs (legacy).

To use Sawmill with Wowza Streaming Engine and later, follow these steps:

  1. Navigate to the Wowza Streaming Engine [install-dir]/conf/log42-config.xml file, and open it in a text editor.
  2. In <Loggers>/<Root level="info>, uncomment the stdout, serverAccess, serverError, serverStats, vhostAccess, and vhostError appender references:
    	<Root level="info">
    		<AppenderRef ref="stdout" level="info"/>
    		<AppenderRef ref="serverAccess" level="info"/>
    		<AppenderRef ref="serverError" level="warn"/>
    		<AppenderRef ref="serverStats" level="info"/>
    		<AppenderRef ref="vhostAccess" level="info"/>
    		<AppenderRef ref="vhostError" level="warn"/>
    		<!-- <AppenderRef ref="applicationAccess" level="info"/> -->
    		<!-- <AppenderRef ref="applicationError" level="warn"/> -->
    		<!-- <AppenderRef ref="applicationInstanceAccess" level="info"/> -->
    		<!-- <AppenderRef ref="applicationInstanceError" level="warn"/> -->

    Wowza Streaming Engine will now write a log file named wowzastreamingengine_stats.log. This is the best log file for log analysis.

  3. Download and install the Sawmill Log File Analysis and Reporting tool.
  4. Run Sawmill and import the Wowza Streaming Engine logs using the filter [install-dir]/logs/wowzastreamingengine_stats.log*.

Sawmill should recognize the Wowza Streaming Engine log file format and report it as Wowza Media Server Log Format.
