+.Sh NAME
+.Nm dwatch
+.Nd watch processes as they trigger a particular DTrace probe
+.Sh SYNOPSIS
+.Nm
+.Op Fl 1defFmnPqRvVwxy
+.Op Fl B Ar num
+.Op Fl E Ar code
+.Op Fl g Ar group
+.Op Fl j Ar jail
+.Op Fl k Ar name
+.Op Fl K Ar num
+.Op Fl M Ar name
+.Op Fl N Ar count
+.Op Fl p Ar pid
+.Op Fl r Ar regex
+.Op Fl t Ar test
+.Op Fl T Ar time
+.Op Fl u Ar user
+.Op Fl z Ar regex
+probe ...
+.Nm
+.Fl l
+.Op Fl fmnPqy
+.Op Fl r Ar regex
+.Op probe ...
+.Nm
+.Fl Q
+.Op Fl 1qy
+.Op Fl r Ar regex
+.Sh DESCRIPTION
+The
+.Nm
+utility uses
+.Xr dtrace 1
+to display process info when DTrace hits a given probe proint.
+.Pp
+.Nm
+automates the process of generating DTrace scripts to coalesce trace output by
+date/time,
+process info,
+and
+.Op optionally
+probe-specific data.
+.Pp
+Output format without options is:
+.Pp
+.Dl date/time uid.gid execname[pid]: psargs
+.Pp
+For example,
+the command
+.Ql dwatch BEGIN
+produces the output:
+.Pp
+.Dl INFO Watching 'dtrace:::BEGIN' ...
+.Dl 2017 May 29 08:23:20 0.0 dtrace[60671]: dtrace -s /dev/stdin
+.Pp
+The
+.Fl F
+option causes
+.Nm
+to instead coalesce trace output by date/time,
+process info,
+and function traversal.
+.Pp
+Output format with
+.Ql Fl F
+option is:
+.Pp
+.Dl date/time uid.gid execname[pid]: [=> |<= ]prov:mod:func:name
+.Pp
+For example,
+the command
+.Ql dwatch -F BEGIN
+produces the output:
+.Pp
+.Dl INFO Watching 'dtrace:::BEGIN' ...
+.Dl 2017 May 29 21:34:41 0.0 dtrace[86593]: dtrace:::BEGIN
+.Pp
+The
+.Fl R
+option causes
+.Nm
+to display a process tree containing the parent,
+grandparent,
+and ancestor process info.
+.Pp
+Output format with
+.Ql Fl R
+option is:
+.Pp
+.Dl date/time uid0.gid0 execname[pid0]: psargs0
+.Dl " -+= pid3 uid3.gid3 psargs3"
+.Dl " \\\-+= pid2 uid2.gid2 psargs2"
+.Dl " \\\-+= pid1 uid1.gid1 psargs1"
+.Dl " \\\-+= pid0 uid0.guid0 psargs0"
+.Pp
+For example,
+the command
+.Ql dwatch -R BEGIN
+produces the output:
+.Pp
+.Dl INFO Watching 'dtrace:::BEGIN' ...
+.Dl 2017 May 29 21:38:54 0.0 dtrace[86899]: dtrace -s /dev/stdin
+.Dl " -+= 86855 604.604 -bash"
+.Dl " \-+= 86857 604.604 /bin/sh /usr/sbin/dwatch -R BEGIN"
+.Dl " \-+= 86897 0.0 sudo dtrace -s /dev/stdin"
+.Dl " \-+= 86899 0.0 dtrace -s /dev/stdin"
+.Pp
+Of particular interest is the ability to filter using regular expressions.
+The
+.Ql Fl g Ar group ,
+.Ql Fl p Ar pid ,
+.Ql Fl r Ar regex ,
+.Ql Fl u Ar user ,
+and
+.Ql Fl z Ar regex
+options can be combined with
+.Ql Fl R
+to match on parent process criteria as well as current process info.
+.Pp
+In contrast,
+the
+.Ql Fl j Ar jail ,
+and
+.Ql Fl k Ar name
+options apply only to the current process even if
+.Ql Fl R
+is given.
+.Pp
+The
+.Ql Fl E Ar code
+option gives the ability to customize probe-specific data.
+For example,
+the command:
+.Pp
+.Dl dwatch -E 'printf("%s", copyinstr(arg0))' chdir
+.Pp
+displays the path argument sent to
+.Xr chdir 2
+calls.
+.Pp
+Profiles can be written for more complex routines or convenience.
+To list available profiles use the
+.Ql Fl Q
+option.
+Use the
+.Ql Fl M Ar name
+option to use a particular profile.
+.Pp
+For example,
+the command
+.Ql dwatch -M kill
+displays arguments sent to
+.Xr kill 2 .
+.Pp
+Since this uses DTrace, only the root user or users with
+.Xr sudo 8
+access can run this command.
+.Sh OPTIONS
+If a
+.Ar probe
+argument does not contain colon
+.Pq Ql Li ":"
+and none of
+.Ql Fl P ,
+.Ql Fl m ,
+.Ql Fl f ,
+or
+.Ql Fl n
+are given,
+the probe argument is intelligently mapped to its most-likely value.
+Use
+.Ql Nm Fl l Ar name
+to see what probes will match a given name.
+.Bl -tag -width "-c count"

+.It Fl e
+Exit after compiling request but prior to enabling probes.
+.It Fl E Ar code
+DTrace
+.Ar code
+for event details.
+If `-',

+Below are some examples of how to use
+.Nm
+to watch system activity:
+.Pp
+.Nm
+.Ar on-cpu
+.Dl Watch processes entering system CPU scheduler.
+.Pp
+.Nm
+.Fl 1
+.Fl Q
+.Dl List available profiles, one line per profile.
+.Pp
+.Nm
+.Fl d
+fsync
+.Dl "Do not" execute Xr dtrace 1 but display script on stdout and exit.
+.Pp
+.Nm
+.Fl e
+.Ar test_probe
+.Dl Compile and test but do not execute code generatd with given probe.
+.Pp
+.Nm
+.Fl E Ar 'printf("%i", arg1)'
+zfs_sync
+.Dl Print argument one being passed to each call of zfs_sync().
+.Pp
+.Nm
+.Fl f

+.Ar ":"
+.Dl Watch all function traversal.
+.Pp
+.Nm
+.Fl F

+.Dl Watch syscall function traversal.
+.Pp
+.Nm
+.Fl g Ar wheel
+execve
+.Dl Display only processes belonging to wheel super-group.
+.Pp
+.Nm
+.Fl g Ar '1|65534'
+.Ar execve
+.Dl Display only processes belonging to groups \
+So Li daemon Sc \
+or \
+So Li nobody Sc .
+.Pp
+.Nm
+.Fl j Ar 0
+execve
+.Dl Ignore jails, displaying only base system processes.
+.Pp
+.Nm
+.Fl j Ar myjail
+execve
+.Dl Display only processes running inside the jail named Ql Li myjail .
+.Pp
+.Nm
+.Fl k Ar 'ruby*'
+.Fl F
+.Ar syscall
+.Dl Watch syscall function traversal by ruby processes.
+.Pp
+.Nm
+.Fl k Ar '*daemon*'
+.Fl F

+The dwatch selection algorithm will commonly favor the function named \
+So Li read Sc \
+when not given a type \
+Po using So Fl P Sc , So Fl m Sc , So Fl f Sc , or So Fl n Sc Pc \
+because there are more probes matching the function named \
+So Li read Sc \
+than probes matching \
+So Li read Sc \
+for any other type.
+.Pp
+.Nm
+.Fl N Ar 1
+kill
+.Dl Display the first process to call Xr kill 2 and then exit.

+.Pp
+.Nm
+.Fl P
+.Ar random
+.Dl Watch the provider \
+So Li random Sc \
+instead of the function \
+So Li random Sc . \
+The dwatch selection algorithm will commonly favor the function named \
+So Li random Sc \
+when not given a type \
+Po using So Fl P Sc , So Fl m Sc , So Fl f Sc , or So Fl n Sc Pc \
