11.0 Debugging Applications
11.1 What’s New in this Chapter
• No updates in this release.
11.2 Management Interface Layer (MIL) Introduction
A reference application called Management Interface Layer (MIL) is provided in order
for the users to make use of the DCC APIs provided. MIL provides a framework for
triggering and logging of various debug features in a uniform and generic manner. The
MIL application by itself does not generate any debug information. MIL makes use of
the APIs exposed by the DCC component and generates a standard Linux* log file
called syslog.
Note: It is the responsibility of the programmer to ensure the syslog maximum size is > 4 k
messages or debug messages may be lost.
Figure 10 illustrates debug components and how they fit together:
The MIL application provides user space commands in order to enable/disable debug
logging as well as trigger logging for Version, Liveness, Data dump as well as SEN
events.
