I’m sure there are many blogs out there that have this solution. But I seem to get asked this question a lot so I thought I would post it here for my convenience.

1. Login to Enterprise Manager, e.g.
   
   http://localhost:7001/em
   
2. Expand the SOA folder and right-click the soa-infra(soa_server1) folder and select Logs – Log Configuration
   
   
   
3. Navigate to the component you want to monitor and change the log level. It is possible to change at a parent level if required
   
   
   
   It is not recommended that you set the level to FINIEST at a parent level as it will generate a lot of logging.
   
4. Make sure you apply the change to take affect.
   
   

Simple as that.
