WARNING: This is work in progress, it should not be used on production servers.

This is PAPMON, The Play APlication MONitoring module.

Its goals are to gather every minutes statistics on :

• The JVM
• Hibernate
• Logs

These statictics are stored in the Play! database.

PAPMON is a regular Play! module, it must be declated in the application.conf. Hibernates statistics are gathered only if 'hibernate.generate_statistics=true' is present in your application.conf.

Some statistics can be used to generate an image (using Google Chart Tools) by using tags:

#{papmon.lineChart stat:'jvm/usedPermGenMemory', title:'Used PermGen memory - Last hour', width:350, height:250, range:'hour' /}
#{papmon.lineChart stat:'hibernate/queryExecutionCount', title:'# of queries - Last hour', width:350, height:250, range:'hour' /}

Futures improvements will include:

• more tags to displays more statistics
• statistics cleaners to unclutter the DB
• javadoc + user guide

Feels free to drop suggestions :)
