EOS Log Library
EOS log library provides integrated logs showing both OS and application logs.
Key features of the logging include:
•
Build time enabling/disabling of log statements. Using a C macro definition, log
statements can be enabled or disabled.
•
Configuration variables to override the default log settings for a task.
•
Log statements can include optional filters, which are evaluated at run time.
Statement is only logged if the filter evaluates to true. Filters will control the
amount of log data.
•
Logged data includes task and source file information.
•
Includes log spooler, which is used to spool a
*LOG
log to a communication
port specified by
*LOGP
. This feature provides real time logging with
timestamps. It is enabled using configuration variable
*LOGSPOOLER
or NCP
menu. The disadvantage is that system wakes up regularly for transmitting log
content and never stays in sleep for longer periods.

System and Communication Programmers Guide, VPN - DOC00302.
