What (free) tools are there for looking at system behavior?


syd, a utility like top, is on the Freeware disk for versions
of Digital UNIX before V3.0. It is also available for anonymous FTP from
many sites. One is ftp://ftp.Uni-Koeln.DE/decosf; and there you can also
get a version that works with version 3.x of Digital UNIX.

The latest official version of top (3.4) supports single cpu
Alphas running Digital UNIX 1.2, 1.3, 2.0, 3.0, and 3.2. It is at
ftp://eecs.nwu.edu/pub/top It does not support multi-cpu alphas,
because no-one with root access to a multi-cpu alpha has stepped forward
to do the work. When compiling, note the warning about compiling
with optimisation.

lsof, a utility for listing open files, is available from:

ftp://vic.cc.purdue.edu/pub/tools/unix/lsof

In addition there is a program for listing locks on files that runs on
3.2 and 4.0 at least in:

ftp://vic.cc.purdue.edu/pub/tools/unix/lslk

vmubc is a graphical and tty-based tool for displaying statistics
on CPU, UBC, and virtual memory. Note that to compile on OSF/1 2.x,
add -DGSI_CPUS_IN_BOX=55 to the CFLAGS. vmubc is available from:

ftp://gatekeeper.dec.com/pub/Digital/vmubc.tar.Z It was written by

George Chaltas of DEC.

sys_check is a ksh script, that generates a HTML file of a Digital UNIX
configuration. It is supported on both V3.2C-G, and V4.0A-D systems. Sys_check
is included in current Tru64 UNIX Operating system releases.
