Mon, 01 Aug 2011 09:43:35 +0000

Get rid of MAXCPU knowledge used for internal needs only. Switch todynamic memory allocation to hold per-CPU memory types data (sized tomp_maxid for UMA, and to mp_maxcpus for malloc to match the kernel).That fixes libmemstat with arbitrary large MAXCPU values and thereforeeliminates MEMSTAT_ERROR_TOOMANYCPUS error type.Reviewed by: jhbApproved by: re (kib) List of files: /freebsd-13.1/lib/libmemstat/libmemstat.3

ba23fa9b - Teach libmemstat(3) how to extract malloc(9) statistics using kvm(3),

Sat, 06 Aug 2005 13:54:03 +0000

Teach libmemstat(3) how to extract malloc(9) statistics using kvm(3),so that libmemstat can be used to view full memory statistics fromkernel core dumps and /dev/mem. This is provided via a new queryfunction, memstat_kvm_malloc(), which is also automatically invokedby memstat_kvm_all(). A kvm handle must be passed in.This will allow malloc(9)-specific code to be removed from vmstat(8). List of files: /freebsd-13.1/lib/libmemstat/libmemstat.3

33c20d18 - Add memstat_kvm_uma(), an implementation of a libmemstat(3) query routine

Mon, 01 Aug 2005 19:07:39 +0000

Add memstat_kvm_uma(), an implementation of a libmemstat(3) query routinethat knows how to extract UMA(9) allocator statistics from a core dump orlive memory image using kvm(3). The caller is expected to provide thenecessary kvm_t handle, which is then used by libmemstat(3).With these changes, it is trivially straight forward to re-introducevmstat -z support on core dumps, which was lost when UMA was introduced.In the short term, this requires including vm/ include files that are notintended for extra-kernel use, requiring in turn some ugliness.

ca108fe2 - UMA supports "secondary" zones, in which a second zone can be layered

Wed, 20 Jul 2005 09:17:40 +0000

UMA supports "secondary" zones, in which a second zone can be layeredon top of a primary zone, sharing the same allocation "keg". Whenreporting statistics for zones, do not report the free items in thekeg as part of the free items in the zone, or those free items willbe reported more than once: for the primary zone, and then anysecondary zones off the primary zone. Separately record and maintaina kegfree statistic, and export via memstat_get_kegfree(), which isavailable for use if needed. Since items free'd back to the keg arenot fully initialized, and hence may not actually be available (sincesecondary zone ctor-time initialization can fail), this makes someamount of sense.This change corrects a bug made visible in the libmemstat(3)modifications to netstat: mbufs freed back to the keg from thepacket zone would be counted twice, resulting in negative valuesbeing printed in the mbuf free count.Some further refinement of reporting relating to secondary zones maystill be required.Reported by: ssouhlalMFC after: 3 days List of files: /freebsd-13.1/lib/libmemstat/libmemstat.3

0cddce49 - Add libmemstat(3), a library for use by debugging and monitoring

Thu, 14 Jul 2005 17:40:02 +0000

Add libmemstat(3), a library for use by debugging and monitoringapplications in tracking kernel memory statistics. It provides anabstracted interface to uma(9) and malloc(9) statistics, wrappedaround the recently added binary stream sysctls for the allocators.Using this interface, it is easy to build monitoring tools, queryspecific memory types for usage information, etc. Facilities areprovided for binding caller-provided data to memory types,incremental updates of memory types, and queries that span multipleallocators.Support for additional allocators is (relatively) easy to add.The API for libmemstat(3) will probably change some over time asconsumers are written, and requirements evolve. It is written toavoid encoding ABIs for data structure layout into consumingapplications for this reason.MFC after: 1 week List of files: /freebsd-13.1/lib/libmemstat/libmemstat.3
