NAME¶

tapset::memory - systemtap memory tapset

DESCRIPTION¶

This family of probe points is used to probe memory-related events.

vm_fault_contains

Test return value for page fault reason

See function::vm_fault_contains(3stap)
for details.

vm.pagefault

Records that a page fault occurred

See probe::vm.pagefault(3stap)
for details.

vm.pagefault.return

Indicates what type of fault occurred

See probe::vm.pagefault.return(3stap)
for details.

addr_to_node

Returns which node a given address belongs to within a NUMA system

See function::addr_to_node(3stap)
for details.

vm.write_shared

Attempts at writing to a shared page

See probe::vm.write_shared(3stap)
for details.

vm.write_shared_copy

Page copy for shared page write

See probe::vm.write_shared_copy(3stap)
for details.

vm.mmap

Fires when an mmap is requested

See probe::vm.mmap(3stap)
for details.

vm.munmap

Fires when an munmap is requested

See probe::vm.munmap(3stap)
for details.

vm.brk

Fires when a brk is requested (i.e. the heap will be resized)

See probe::vm.brk(3stap)
for details.

vm.oom_kill

Fires when a thread is selected for termination by the OOM killer

See probe::vm.oom_kill(3stap)
for details.

vm.kmalloc

Fires when kmalloc is requested

See probe::vm.kmalloc(3stap)
for details.

See probe::vm.kmem_cache_alloc(3stap)
for details.

vm.kmalloc_node

Fires when kmalloc_node is requested

See probe::vm.kmalloc_node(3stap)
for details.

vm.kmem_cache_alloc_node

Fires when kmem_cache_alloc_node is requested

See probe::vm.kmem_cache_alloc_node(3stap)
for details.

vm.kfree

Fires when kfree is requested
