ATM Configuration and Troubleshooting Guide

Logging and Tracing ATM Activity
Tracing
Chapter 10 293
NOTE When tracing begins, two additional nettl daemons begin execution. If
you issue a ps command, you will see four processes: two shown as
ntl_reader and two shown as nktl_daemon. One pair of nettl daemons
is dedicated to network logging and one pair is concerned with tracing.
There is also a netfmt process running, to send disaster log messages to
the system console.
Verifying Status
Use the command nettl -ss to verify the status of the tracing. The
output should be similar to this (the ATM information is shown in bold
in this example):
Logging Information:

User’s ID: 0 Buffer Size: 32768

The information at the end of the display shows that tracing has started.
All ATM adapters are traced at the same time, and all the trace
information is sent to the same log file. You need to filter the information
with NetFmt to view the information for one ATM adapter (see “Viewing
Trace Files” on page 296).
