Introduction
The logfiles in the /dvs/dncs/tmp directory contain important
information about how the DNCS processes are operating. As the
processes run, they typically write entries into their associated logfiles
that provide system operators and Cisco engineers with valuable
debugging information. A typical entry into a logfile contains a time-
stamp, as well as the current values of the software parameters and
variables coded into the processes. Cisco engineers developed the qtail
and sesstail utilities to help system operators and engineers monitor
the DNCS logfiles.
