NetTL (Network Tracing and Logging facility) is
the facility used by network drivers and modules to capture network
error events or trace data. In HP-UX 10.0, a mechanism will enable
STREAMS/UX to deliver log/trace messages to NetTL. Previously, STREAMS/UX
had its own error logging and tracing facility.
This chapter describes the STREAMS/UX-NetTL link, which integrates the
STREAMS/UX logging and tracing facility with NetTL. STREAMS/UX error
and trace messages generated by strlog() or by putmsg() to a STREAMS/UX log driver can also be delivered
to NetTL with the STREAMS/UX-NetTL link.
With the STREAMS/UX-NetTL link, a single common interface
for network tracing and logging will exist. Also, STREAMS/UX logging
can benefit from NetTL's powerful features like message filtering.
Implementation of the STREAMS/UX-NetTL link is transparent
to strerr and strace users. These commands work just as before even when
NetTL is running.
