FYI: I've begun the MFC of procstat(1) from HEAD to RELENG_7. This requires
merging a number of kernel changes, and then the command line tool, so it
will occur over the next day or so. I'll send out a further e-mail when the
merge is done.
I believe that the MFC is now complete. If you run into any problems with
this tool, please file a PR and I'll try to address it. Two areas where I
would like to do future work, and would also greatfully accept contributions,
are:
(1) Adding libkvm support, allowing procstat to be used on crashdumps.
(2) Adding a signal information dump mode, providing information on what
signal handlers (etc) have been set to non-default dispositions.
(3) Add user thread stack tracing support similar to kernel thread stack
tracing support.

Subject: procstat(1) committed to CVS HEAD
Dear all, (and FYI to hackers@ where I previousl sought feedback):
I've now committed procstat(1) to CVS. I've found it to be quite a helpful
debugging tool, am particularly pleased with -k/-kk, and would welcome
feedback and ideas on further improving it.

Added files:
usr.bin/procstat Makefile procstat.1 procstat.c procstat.h

Log:
Add procstat(1), a process inspection utility. This provides both some
of the missing functionality from procfs(4) and new functionality for
monitoring and debugging specific processes. procstat(1) operates in
the following modes:
-b Display binary information for the process.
-c Display command line arguments for the process.
-f Display file descriptor information for the process.
-k Display the stacks of kernel threads in the process.
-s Display security credential information for the process.
-t Display thread information for the process.
-v Display virtual memory mappings for the process.
Further revision and modes are expected.
