bawrite
| Probe that fires whenever a buffer is about to be asynchronously written
out to a device.
|
bread
| Probe that fires whenever a buffer is physically read from a device.
bread fires after the buffer has been requested from
the device, but before blocking pending its completion.
|
bwrite
| Probe that fires whenever a buffer is about to be written out to a device,
whether synchronously or asynchronously.
|
cpu_ticks_idle
| Probe that fires when the periodic system clock has made the determination
that a CPU is idle. Note that this probe fires in the
context of the system clock and therefore fires on the CPU running the system
clock. The cpu_t argument ( arg2) indicates
the CPU that has been deemed idle. See Arguments for
details.
|
cpu_ticks_kernel
| Probe that fires when the periodic system clock has made the determination
that a CPU is executing in the kernel. This probe fires
in the context of the system clock and therefore fires on the CPU running
the system clock. The cpu_t argument ( arg2)
indicates the CPU that has been deemed to be executing in the kernel. See Arguments for details.
|
cpu_ticks_user
| Probe that fires when the periodic system clock has made the determination
that a CPU is executing in user mode. This probe fires
in the context of the system clock and therefore fires on the CPU running
the system clock. The cpu_t argument ( arg2)
indicates the CPU that has been deemed to be running in user-mode. See Arguments for details.
|
cpu_ticks_wait
| Probe that fires when the periodic system clock has made the determination
that a CPU is otherwise idle, but some threads are waiting for I/O on the
CPU. This probe fires in the context of the system clock and therefore fires
on the CPU running the system clock. The cpu_t argument
( arg2) indicates the CPU that has been deemed waiting on
I/O. See Arguments for details.
|
idlethread
| Probe that fires whenever a CPU enters the idle loop.
|
intrblk
| Probe that fires whenever an interrupt thread blocks.
|
inv_swtch
| Probe that fires whenever a running thread is forced to involuntarily
give up the CPU.
|
lread
| Probe that fires whenever a buffer is logically read from a device.
|
lwrite
| Probe that fires whenever a buffer is logically written to a device.
|
modload
| Probe that fires whenever a kernel module is loaded.
|
modunload
| Probe that fires whenever a kernel module is unloaded.
|
msg
| Probe that fires whenever a msgsnd(2) or msgrcv(2) system call is made, but before the message queue operations
have been performed.
|
mutex_adenters
| Probe that fires whenever an attempt is made to acquire an owned adaptive
lock. If this probe fires, one of the lockstat provider's adaptive-block or adaptive-spin probes will also
fire. See lockstat Provider for
details.
|
namei
| Probe that fires whenever a name lookup is attempted in the filesystem.
|
nthreads
| Probe that fires whenever a thread is created.
|
phread
| Probe that fires whenever a raw I/O read is about to be performed.
|
phwrite
| Probe that fires whenever a raw I/O write is about to be performed.
|
procovf
| Probe that fires whenever a new process cannot be created because the
system is out of process table entries.
|
pswitch
| Probe that fires whenever a CPU switches from executing one thread to
executing another.
|
readch
| Probe that fires after each successful read, but before control is returned
to the thread performing the read. A read may occur through the read(2), readv(2) or pread(2) system
calls. arg0 contains the number of bytes that were successfully
read.
|
rw_rdfails
| Probe that fires whenever an attempt is made to read-lock a readers/writer
when the lock is either held by a writer, or desired by a writer. If this
probe fires, the lockstat provider's rw-block probe
will also fire. See lockstat
Provider for details.
|
rw_wrfails
| Probe that fires whenever an attempt is made to write-lock a readers/writer
lock when the lock is held either by some number of readers or by another
writer. If this probe fires, the lockstat provider's rw-block probe will also fire. See lockstat Provider for details.
|
sema
| Probe that fires whenever a semop(2) system call
is made, but before any semaphore operations have been performed.
|
sysexec
| Probe that fires whenever an exec(2) system call
is made.
|
sysfork
| Probe that fires whenever a fork(2) system call
is made.
|
sysread
| Probe that fires whenever a read(2), readv(2), or pread(2) system call is made.
|
sysvfork
| Probe that fires whenever a vfork(2) system call
is made.
|
syswrite
| Probe that fires whenever a write(2), writev(2), or pwrite(2) system call is made.
|
trap
| Probe that fires whenever a processor trap occurs. Note that some processors,
in particular UltraSPARC variants, handle some light-weight traps through
a mechanism that does not cause this probe to fire.
|
ufsdirblk
| Probe that fires whenever a directory block is read from the UFS file
system. See ufs(7FS) for details on UFS.
|
ufsiget
| Probe that fires whenever an inode is retrieved. See ufs(7FS) for
details on UFS.
|
ufsinopage.
| Probe that fires after an in-core inode without any associated data
pages has been made available for reuse. See ufs(7FS) for
details on UFS.
|
ufsipage
| Probe that fires after an in-core inode with associated data pages has
been made available for reuse. This probe fires after the associated data
pages have been flushed to disk. See ufs(7FS) for details
on UFS.
|
wait_ticks_io
| Probe that fires when the periodic system clock has made the determination
that a CPU is otherwise idle but some threads are waiting for I/O on the CPU.
This probe fires in the context of the system clock and therefore fires on
the CPU running the system clock. The cpu_t argument ( arg2) indicates the CPU that is described as waiting for I/O. See Arguments for details on arg2.
No semantic difference between wait_ticks_io and cpu_ticks_wait; wait_ticks_io exists solely for historical
reasons.
|
writech
| Probe that fires after each successful write, but before control is
returned to the thread performing the write. A write may occur through the write(2), writev(2) or pwrite(2) system
calls. arg0 contains the number of bytes that were successfully
written
|
xcalls
| Probe that fires whenever a cross-call is about to be made. A cross-call
is the operating system's mechanism for one CPU to request immediate work
of another CPU.
