 8 order, from an FDUMP.  Those events considered to be interesting are
 9 described in 'notes'.

12 Control arguments:
13 -exclude STRING, -ex STRING
14    does not print lines containing STRING.  Exclusion is done after
15    matching.  Thus, "-match A -exclude B" prints all lines with an A
16    except those with a B.
17 -exclude /REGEXP/, -ex /REGEXP/
18    does not print lines containing a string matching the regular
19    expression REGEXP.  (See the qedx command for the definition of
20    regular expressions.)
21 -last {N}, -lt {N}
22    specifies the number of events to print. If no N, the default is
23    10 events.
24 -long, -lg
25    specifies that disk queue events are to be displayed.
26 
27 
28 -match STRING, -mh STRING
29    prints only lines containing the character string STRING.
30 -match /REGEXP/, -mh /REGEXP/
31    prints only lines containing a string matching the regular
32    expression REGEXP.
33 -time {NSECS}, -tm {NSECS}
34    specifies the time in seconds before the dump was taken when events
35    were 'interesting'.  Default is 10 seconds.

37 
38 Notes: The following events are considered as interesting: Machine
39 Conditions (from BCE, prds, pds and the mc_trace_buf), Traffic Control
40 state change time, Syserr messages (from both syserr_data and
41 syserr_log), Fim frames in any stack, connects by device and disk
42 queues (long report ONLY).
43 
44 If neither -time nor -last are specified, the default action is
45 equivalent to "ev -time 10".
