tapset::memory (3stap)

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.

vm.kmem_cache_alloc

Fires when kmem_cache_alloc is requested

• 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

• See probe::vm.kfree(3stap) for details.

vm.kmem_cache_free

Fires when kmem_cache_free is requested

• See probe::vm.kmem_cache_free(3stap) for details.
