Logging and Tracing Messages
HP LAN/9000 comes with an online message catalog that reports LAN
problems, probable causes, and actions for you to take to correct the
problems. Messages are sent either to the system console or log files
based on the logging and tracing configuration. To view the probable
cause and action text of the message, use the netfmt command with the
-v option. Below is an example.
# netfmt -v -f /var/adm/nettl.LOG00

HP LAN/9000 uses the nettl logging and tracing facility supplied with
HP-UX to capture, control, and format messages produced by LAN. See
the nettl(1M) man page for information on using the graphical user
interface or command line interface. The graphical interface, which is
accessed by running the nettladm command, includes the following
features:
• screens which take you through any logging or tracing task desired
• screens which allow you to create and format reports
• the capability of logging and tracing subsystem-specific information
• main screens which are updated instantaneously with current
logging and tracing information by subsystem
• context-sensitive on-line help
