Controlling tracing

Tracing is the ability to record a set of events. Novera EPIC tracing controls the generation of messages from your clients and services. You can generate three levels of log file information using the Novera EPIC Management System:

nov00000.gif Application tracing provides clients and applications with a mechanism for controlling the display of messages to standard output.

nov00000.gif Method tracing directs Novera EPIC to write the method names being executed in a service to standard output. If the service is running inside the Novera EPIC Kernel, Novera EPIC sends method tracing information to the Novera EPIC Kernel log file kernel_name.epickrnl.log, where kernel_name is the name of the Novera EPIC Kernel. If the service is running outside the Novera EPIC Kernel, Novera EPIC sends method tracing information to standard output.

nov00000.gif Message tracing directs Novera EPIC to write kernel-level messages to the Novera EPIC log file kernel_name.epickrnl.log, where kernel_name is the name of the Novera EPIC Kernel. Message tracing is applicable only to services running inside the Novera EPIC Kernel.
