NETTRDUMP(1M)  —  Series 300 and 800 Only

NAME

nettrdump − dump the contents of the trace buffer

SYNOPSIS

/usr/bin/nettrdump [ -b ] [ -c corefile ] [ -h [ kernel ] ]
 
The Series 300 does not implement the -c corefile option. 

DESCRIPTION

Nettrdump dumps the current contents of the trace kernel buffer to standard output.  This command requires super-user capability for all but the nettrdump −c corefile usage.  HP recommends that you not use the nettrdump command after issuing a nettrstart −f filename command without first executing nettrstop -p.  The two commands may interfere with each other and produce inconsistent results. 

The nettrdump options are:

-b Dump the kernel buffer in binary form for later formatting.  Default: Dump the kernel buffer in formatted form. 

−c corefile Extract tracing information from the core dump file corefile. Useful after a system crash.  Super-user capability not required.
 
The Series 300 does not use this option. It defaults to /dev/kmem instead. 

−h [ kernel ] Extract tracing information from the kernel file.  Default: /hp-ux. 

FILES

/dev/nsdiag1 NS diagnostics multiple access device file used for ioctl()’s.

DIAGNOSTICS

Messages indicate incorrect usage, network tracing had not been started when a dump was initiated or a dump was attempted before executing nettrstop -p, the file could not be opened, or the user is not privileged. 

DEPENDENCIES

Implemented on the Series 300 and 800 only.
