<p>The module <c>instrument</c> contains support for studying the resource
@@ -41,387 +41,190 @@
<note>
<p>Note that this whole module is experimental, and the representations
used as well as the functionality is likely to change in the future.</p>
- <p>The <c>instrument</c> module interface was slightly changed in
- Erlang/OTP R9C.</p>
</note>
- <p>To start an Erlang runtime system with instrumentation, use the
- <c>+Mi*</c> set of command-line arguments to the <c>erl</c> command (see
- the erts_alloc(3) and erl(1) man pages).</p>
- <p>The basic object of study in the case of memory allocation is a memory
- allocation map. A memory allocation map contains a list of descriptors
- for each allocated memory block. Currently, a descriptor is a 4-tuple</p>
- <pre>
- {TypeNo, Address, Size, PidDesc} </pre>
- <p>where <c>TypeNo</c> is the memory block type number, <c>Address</c>
- is its place in memory, and <c>Size</c> is its size, in bytes.
- <c>PidDesc</c> is either a tuple <c>{X,Y,Z}</c> identifying the
- process which was executing when the block was allocated, or
- <c>undefined</c> if no process was executing. The pid tuple
- <c>{X,Y,Z}</c> can be transformed into a real pid by usage of the
- <c>c:pid/3</c> function.</p>
- <p>Various details about memory allocation:</p>
- <p>Memory blocks are allocated both on the heap segment and on other memory
- segments. This can cause the instrumentation functionality to report
- very large holes. Currently the instrumentation functionality doesn't
- provide any support for distinguishing between holes between memory
- segments, and holes between allocated blocks inside memory segments.
- The current size of the process cannot be obtained from within Erlang,
- but can be seen with one of the system statistics tools, e.g.,
- <c>ps</c> or <c>top</c>. The Solaris utility <c>pmap</c> can be
- useful. It reports currently mapped memory segments. </p>
- <p>Overhead for instrumentation: When the emulator has been started with
- the <seealso marker="erts:erts_alloc#Mim">"+Mim true"</seealso>
- flag, each block is preceded by a 24 bytes large
- header on a 32-bit machine and a 48 bytes large header on a 64-bit
- machine. When the emulator has been started with the
- <seealso marker="erts:erts_alloc#Mis">"+Mis true"</seealso>
- flag, each block is preceded by an 8 bytes large header. These are the header
- sizes used by the Erlang 5.3/OTP R9C emulator. Other versions of the
- emulator may use other header sizes. The function
- <seealso marker="#block_header_size/1">block_header_size/1</seealso>
- can be used for retrieving the header size used for a specific memory
- allocation map. The time overhead for managing the instrumentation
- data is small.</p>
- <p>Sizes presented by the instrumentation functionality are (by the
- emulator) requested sizes, i.e. neither instrumentation headers nor
- headers used by allocators are included.</p>
