anonfree
| Probe that fires whenever an unmodified anonymous page is freed as part
of paging activity. Anonymous pages are those that are not associated with
a file. Memory containing such pages includes heap memory, stack memory, or
memory obtained by explicitly mapping zero(7D).
|
anonpgin
| Probe that fires whenever an anonymous page is paged in from a swap
device.
|
anonpgout
| Probe that fires whenever a modified anonymous page is paged out to
a swap device.
|
as_fault
| Probe that fires whenever a fault is taken on a page and the fault is
neither a protection fault nor a copy-on-write fault.
|
cow_fault
| Probe that fires whenever a copy-on-write fault is taken on a page. arg0 contains the number of pages that are created as a result of
the copy-on-write.
|
dfree
| Probe that fires whenever a page is freed as a result of paging activity.
Whenever dfree fires, exactly one of anonfree, execfree or fsfree will also subsequently fire.
|
execfree
| Probe that fires whenever an unmodified executable page is freed as
a result of paging activity.
|
execpgin
| Probe that fires whenever an executable page is paged in from the backing
store.
|
execpgout
| Probe that fires whenever a modified executable page is paged out to
the backing store. Most paging of executable pages occurs in terms of execfree. execpgout can only fire if an executable page
is modified in memory, an uncommon occurrence in most systems.
|
fsfree
| Probe that fires whenever an unmodified file system data page is freed
as part of paging activity.
|
fspgin
| Probe that fires whenever a file system page is paged in from the backing
store.
|
fspgout
| Probe that fires whenever a modified file system page is paged out to
the backing store.
|
kernel_asflt
| Probe that fires whenever a page fault is taken by the kernel on a page
in its own address space. Whenever kernel_asflt fires,
it will be immediately preceded by a firing of the as_fault probe.
|
maj_fault
| Probe that fires whenever a page fault is taken that results in I/O
from a backing store or swap device. Whenever maj_fault fires,
it will be immediately preceded by a firing of the pgin probe.
|
pgfrec
| Probe that fires whenever a page is reclaimed off of the free page list.
|
pgin
| Probe that fires whenever a page is paged in from the backing store
or from a swap device. This probe differs from maj_fault in
that maj_fault only fires when a page is paged in as a
result of a page fault. pgin fires every time a page is
paged in, regardless of the reason.
|
pgout
| Probe that fires whenever a page is paged out to the backing store or
to a swap device.
|
pgpgin
| Probe that fires whenever a page is paged in from the backing store
or from a swap device. The only difference between pgpgin and pgin is that pgpgin contains the number of pages
paged in as arg0. pgin always contains
1 in arg0.
|
pgpgout
| Probe that fires whenever a page is paged out to the backing store or
to a swap device. The only difference between pgpgout and pgout is that pgpgout contains the number of
pages paged out as arg0. (pgout always
contains 1 in arg0.)
|
pgrec
| Probe that fires whenever a page is reclaimed.
|
pgrrun
| Probe that fires whenever the pager is scheduled.
|
pgswapin
| Probe that fires whenever pages from a swapped-out process are swapped
in. The number of pages swapped in is contained in arg0.
|
pgswapout
| Probe that fires whenever pages are swapped out as part of swapping
out a process. The number of pages swapped out is contained in arg0.
|
prot_fault
| Probe that fires whenever a page fault is taken due to a protection
violation.
|
rev
| Probe that fires whenever the page daemon begins a new revolution through
all pages.
|
scan
| Probe that fires whenever the page daemon examines a page.
|
softlock
| Probe that fires whenever a page is faulted as a part of placing a software
lock on the page.
|
swapin
| Probe that fires whenever a swapped-out process is swapped back in.
|
swapout
| Probe that fires whenever a process is swapped out.
|
zfod
| Probe that fires whenever a zero-filled page is created on demand.
