|
---|
19 | *
|
---|
20 | * The purpose for the statistics manager is to present the rest of the system
|
---|
21 | * with a somewhat uniform way of accessing VMM statistics. STAM sports a
|
---|
22 | * couple of different APIs for accessing them: STAMR3EnumU, STAMR3SnapshotU,
|
---|
23 | * STAMR3DumpU, STAMR3DumpToReleaseLogU and the debugger. Main is exposing the
|
---|
24 | * XML based one, STAMR3SnapshotU.
|
---|
25 | *
|
---|
26 | * The rest of the VMM together with the devices and drivers registers their
|
---|
27 | * statistics with STAM giving them a name. The name is hierarchical, the
|
---|
28 | * components separated by slashes ('/') and must start with a slash.
|
---|
29 | *
|
---|
30 | * Each item registered with STAM - also, half incorrectly, called a sample -
|
---|
31 | * has a type, unit, visibility, data pointer and description associated with it
|
---|
32 | * in addition to the name (described above). The type tells STAM what kind of
|
---|
33 | * structure the pointer is pointing to. The visibility allows unused
|
---|
34 | * statistics from cluttering the output or showing up in the GUI. All the bits
|
---|
35 | * together makes STAM able to present the items in a sensible way to the user.
|
---|
36 | * Some types also allows STAM to reset the data, which is very convenient when
|
---|
37 | * digging into specific operations and such.
|
---|
38 | *
|
---|
39 | * PS. The VirtualBox Debugger GUI has a viewer for inspecting the statistics
|
---|
40 | * STAM provides. You will also find statistics in the release and debug logs.
|
---|
41 | * And as mentioned in the introduction, the debugger console features a couple
|
---|
42 | * of command: .stats and .statsreset.
