Log Files
CERNR4 logs some events, such as failed calls, in the file:
DECNET$LOG:NETEVENTS.LOG
This file is renamed at midnight to decnet$log:netevents.old and the last
10 versions are kept.
This file is shared by all DECrouters at CERN. To find specific entries related
to CERNR4, search the file for the string 'cernr4'.
TRACE
The commands to trace all X25 Level 3 traffic on CERNR4 are given below. Note
that this will create a LOT OF DATA in files called trace.dat in your current
directory. Running trace for 3-10 mins is usually long enough. The trace
command may only be possible from UXCSB1.
$ set proc/priv=oper
$ trace/router start cernr4"cern tracex25"::x25l3line
.... now let trace run for a few minutes ....
$ trace/router stop
$ trace/router analyze/out=trace.lis/data=ascii/wid=80
$ set proc/priv=nooper
The result of the trace will be in the file trace.lis in your current
directory. You can now scan this with the editor, for example.
A full desription of the X25router trace facility along with other diagnosis
facilities is contained in the section 'Problem Solving Guide' of the X25router
2000 manual. There is a copy on the shelf behind the desk of Denise Heagerty (Bld 31-2-016).
