stats: memory heap counters
- Add counters for the main-heap - Add additional counters per heap: STAT_MEM_TOTAL STAT_MEM_USED, STAT_MEM_FREE, STAT_MEM_USED_MMAP, STAT_MEM_TOTAL_ALLOC, STAT_MEM_FREE_CHUNKS, STAT_MEM_RELEASABLE, The per-heap counters are organised as a two dimensional vector. total, used and free are directly available via symlinks. vpp_get_stats ls "^/mem/" /mem/stat segment /mem/stat segment/total /mem/stat segment/used /mem/stat segment/free /mem/main heap /mem/main heap/total /mem/main heap/used /mem/main heap/free vpp_get_stats dump "^/mem/main\ heap$" [0 @ 0]: 1073741776 packets /mem/main heap [1 @ 0]: 91586688 packets /mem/main heap [2 @ 0]: 982155088 packets /mem/main heap [3 @ 0]: 0 packets /mem/main heap [4 @ 0]: 1073741776 packets /mem/main heap [5 @ 0]: 433 packets /mem/main heap [6 @ 0]: 981708688 packets /mem/main heap Type: feature Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I36725dde3b4b3befd27a8b4d3ba931f2d3b627cc
