The location of the debug information depends on the setting of the com.iplanet.services.debug.directory attribute in the AMConfig-instance-name.properties file on the Portal Server node.
For example, if the value of the com.iplanet.services.debug.directory attribute is:
/var/opt/SUNWam/debug/
Then the debug information for Netlet is available in the srapNetlet file in the /var/opt/SUNWam/debug directory.
