Yes, the reason I'm concerned is that we projected much lower memory usage based on the calculations. We originally provisioned 2x the required memory and it appears that this will not be enough.
Am I correct in that the top cmd's RES memory for the beam.smp command is the memory being used by riak for "key storage", if the server was to be rebooted the memory would eventually climb back to this level?

Using more memory than the calculation suggests is normal and expected with Riak. As you increase load on this cluster memory use may go up further as the operating system manges disk operations and buffers. Is there a reason you're concerned about this usage? -- Luke Bakken Engineer lbak...@basho.com On Mon, Jul 18, 2016 at 8:28 AM, Travis Kirstine <tkirst...@firstbasesolutions.com> wrote: > Yes from the free command > > [root@riak1 ~]# free -g > total used free shared buff/cache > available > Mem: 45 9 0 0 36 > 35 > Swap: 23 0 22 > > Or from top > > PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND > 24421 riak 20 0 16.391g 8.492g 41956 S 82.7 18.5 10542:10 beam.smp > > > I don't think that we are IO bound > dstat > > ----total-cpu-usage---- -dsk/total- -net/total- ---paging-- ---system-- > usr sys idl wai hiq siq| read writ| recv send| in out | int csw > 0 0 99 0 0 0| 150k 633k| 0 0 | 1B 25B| 702 2030 > 0 5 95 0 0 0| 0 0 | 10k 2172B| 0 0 |1125 765 > 2 6 92 0 0 0| 0 0 | 213k 135k| 0 0 |2817 7502 > 2 5 92 0 0 0| 0 0 | 159k 88k| 0 0 |2758 9834 > 2 5 93 0 0 0| 0 4884k| 278k 70k| 0 0 |2923 7453 > 0 5 95 0 0 0|4096B 10M| 21k 1066B| 0 0 |3121 781 > 4 7 89 0 0 0| 0 10M| 258k 160k| 0 0 | 13k 16k > 0 5 95 0 0 0| 0 4096B| 200k 65k| 0 0 |1413 1589 > 1 5 92 1 0 0| 0 26k| 287k 206k| 0 0 |2124 4990 > 1 4 95 0 0 0| 0 2048B| 67k 78k| 0 0 |1667 4504 > 1 4 95 0 0 0| 0 1560k| 102k 105k| 0 0 |1639 4146 > 3 8 88 1 0 0| 0 86M| 453k 335k| 0 0 |6097 16k > 4 14 81 0 0 0| 0 15k| 635k 564k| 0 0 |5383 14k > 0 4 96 0 0 0| 0 0 | 29k 1697B| 0 0 |1121 769 > 4 7 89 0 0 0| 0 0 | 339k 376k| 0 0 |8017 15k > 5 16 79 0 0 0| 0 11M| 847k 824k| 0 0 | 13k 30k > 2 12 86 1 0 0|4096B 10M| 301k 272k| 0 0 |4639 11k > 3 10 87 0 0 0| 0 10M| 508k 610k| 0 0 |8260 17k > 2 9 87 2 0 0| 0 13k| 523k 354k| 0 0 |3432 10k > 0 4 96 0 0 0| 0 0 |3434B 1468B| 0 0 |1063 774 _______________________________________________ riak-users mailing list riak-users@lists.basho.com http://lists.basho.com/mailman/listinfo/riak-users_lists.basho.com
