Working with Wowza logs


Improve logs management and rotation over linux, combining Log4j and LogRotate.

Modify the log4j.properties for using other Appender:

# Access appender
log4j.appender.serverAccess=org.apache.log4j.RollingFileAppender
log4j.appender.serverAccess.File=${com.wowza.wms.ConfigHome}/logs/wowzamediaserver_access.log
log4j.appender.serverAccess.layout=com.wowza.wms.logging.ECLFPatternLayout
log4j.appender.serverAccess.layout.Fields=date,time,tz,x-event,x-category,x-severity,x-status,x-ctx,x-comment,x-vhost,x-app,x-appinst,x-duration,s-ip,s-port,s-uri,c-ip,c-proto,c-referrer,c-user-agent,c-client-id,cs-bytes,sc-bytes,x-stream-id,x-spos,cs-stream-bytes,sc-stream-bytes,x-sname,x-sname-query,x-file-name,x-file-ext,x-file-size,x-file-length,x-suri,x-suri-stem,x-suri-query,cs-uri-stem,cs-uri-query
log4j.appender.serverAccess.layout.OutputHeader=true
log4j.appender.serverAccess.layout.QuoteFields=false
log4j.appender.serverAccess.layout.Delimeter=tab

Create the logrotate configuration file into Centos/RedHat the path is:

nano /etc/logrotate.d/wowza
/usr/local/WowzaMediaServer/logs/*.log {
       rotate 3
       size=512M
       compress
       copytruncate
       missingok
}

And the last step is you have very big logs files like is my case, and into one day I can have 2 GB of logs or more, move the log rotate for check every hour instead of every day

mv /etc/cron.daily/logrotate /etc/cron.hourly/

UPDATE:
Other way to work with Wowza logs, can be using external Jar for rotate the logs by Size and Time, this way if you are running into WinOS or don’t like to use LogRotate for this task can have similar functionality
