Robert Watson cd814b2692 Introduce a new sysctl, kern.malloc_stats, which exports kernel malloc ... statistics via a binary structure stream: - Add structure 'malloc_type_stream_header', which defines a stream version, definition of MAXCPUS used in the stream, and a number of malloc_type records in the stream. - Add structure 'malloc_type_header', which defines the name of the malloc type being reported on. - When the sysctl is queried, return a stream header, followed by a series of type descriptions, each consisting of a type header followed by a series of MAXCPUS malloc_type_stats structures holding per-CPU allocation information. Typical values of MAXCPUS will be 1 (UP compiled kernel) and 16 (SMP compiled kernel). This query mechanism allows user space monitoring tools to extract memory allocation statistics in a machine-readable form, and to do so at a per-CPU granularity, allowing monitoring of allocation patterns across CPUs in order to better understand the distribution of work and memory flow over multiple CPUs. While here: - Bump statistics width to uint64_t, and hard code using fixed-width type in order to be more sure about structure layout in the stream. We allocate and free a lot of memory. - Add kmemcount, a counter of the number of registered malloc types, in order to avoid excessive manual counting of types. Export via a new sysctl to allow user-space code to better size buffers. - De-XXX comment on no longer maintaining the high watermark in old sysctl monitoring code. A follow-up commit of libmemstat(3), a library to monitor kernel memory allocation, will occur in the next few days. Likewise, similar changes to UMA.		2005-07-14 11:52:06 +00:00
