Log Files
A current log is created for each webapp in the directory \{catalina.base}/logs/
...
The logback config file is in WEB-INF/classes in each webapp directory and can be edited.
For example, for the nodecollector* webapp, the default file would be /opt/abiquo/tomcat/webapps/nodecollector/WEB-INF/classes/logback.xml
(*Nodecollector is the name of the webapp for the Discovery Manager Remote Service).
Log Level Example
The default logback.xml file for the VSM is shown here. Note that some of the loggers are set to a log level of TRACE. This log level can create large logs. A log level of DEBUG should be sufficient for both the VSM and BPM.

Disk Requirements
This section describes how to calculate the disk space requirements for the webapp logs. Customers must determine their own logging requirements.Abiquo recommends that you keep approximately one months' worth of files
