5.11.1 Output trigger of event log of the Explicit Memory Management functionality

This subsection describes the output trigger for event log of the Explicit Memory Management functionality. The events triggered differ depending on the set log output level.

The log output level comprises of three types; normal, verbose and debug. When you specify verbose, besides the contents output to normal, the contents corresponding to verbose are output. When you specify debug, besides the contents output to verbose, the contents corresponding to debug are output.

The following table describes the correspondence between log output levels and the events that trigger the output. Prefixes output for the corresponding events are also displayed in the following table. See the reference sections for contents output to each event.
