* tapset/perf.stp: Add 'em.

Complete the renaming scheme with prefix of "tapset::" for the man
pages related to over all description of groups of probes.
|
| |
|
|
| |
The line spacing is significant to the way the output is rendered.

(And incidentally re-enable quiet builds at the same time...)

events. The probes mirror many of the SNMP statistics defined
in /usr/include/linux/snmp.h. Each probe represents a single SNMP
statistic or MIB. Each of the probe's handler is called when system
performs an operation that would alter the associated statistic. Along
with each probe is defined an indexed set of counters used to record
probe hits. The probe handlers call a user supplied callback functions
to determine which counter to alter. The user's callback should returns a
key value that will be used to index the counter. For example a callback
could return a unique value for each socket. This would results in a
separate counter being used for each socket.
tcpipstat.stp shows how snmp tapsets could be used. Tcpipstat collects and
displays network statistics related to individual TCP sockets or groups of
sockets. The statistics that are collected are simmer to that of the command
netstat -s, only sorted and grouped by individual sockets.

The overlapping process.* tapsets are now separated. Those probe points
documented in stapprobes(3stap) remain the same. Those that were formerly
in stapprobes.process(3stap) have been renamed to kprocess, to reflect
their kernel perspective on processes.

document signal syscall
hookiddefs.stp:
some changes to the hookid:
Now the hookid of a return type event(addevent.*.return)
should be an even number and its value should be the
corresponding entry event hookid +1.
The hookid of a non-return type event should be an odd
number.
Add the hookid of HOOKID_REGEVTDESC
register_event.stp:
add register_evt_desc() to register the description of an event.
Change the register_sys_event() to add the an argument
representing event description
Allow to use empty format string and empty field name when
calling register_event().
Change all calling to register_sys_event() to add an
argument which represents the event description.
Change register_evt_desc() and register_event() to add an argument
representing the event description string, which could help
facilitate the error debugging.
iosyscall.stp:
bugfix to add the variable GroupID and hookID
nfs.stp:
bugfix to add some omitted probe definitions.
nfs_proc.stp:
bugfix of the wrong calling to _lket_trace() for
nfs_proc.remove.entry.
