Not showing correct values for stats

[robross0606]

For some reason, the statistics are "flat-lining" in the GUI even though docker stats shows the correct values. For example, my container "tatest" has 4GB of RAM allocated:

CONTAINER ID   NAME      CPU %     MEM USAGE / LIMIT   MEM %     NET I/O           BLOCK I/O   PIDS
85e0510920f7   stats     1.99%     79.06MiB / 256MiB   30.88%    6.34MB / 18.5MB   0B / 0B     23  
b0c7fce89260   latest    0.28%     1.34GiB / 3.84GiB   34.90%    914MB / 1.01GB    0B / 0B     34  
cf4fc69392eb   jaeger    0.08%     12.55MiB / 512MiB   2.45%     1.73kB / 0B       0B / 0B     10  
8dea7a0de998   383       0.72%     106.8MiB / 512MiB   20.87%    12MB / 12MB       0B / 0B     92  

This has also been confirmed from the CLI inside the container:

Mem: 3295556K used, 730512K free, 393644K shrd, 152664K buff, 758780K cached
CPU:   0% usr   0% sys   0% nic  98% idle   0% io   0% irq   0% sirq
Load average: 0.02 0.23 0.53 2/896 284
  PID  PPID USER     STAT   VSZ %VSZ CPU %CPU COMMAND
    1     0 root     S    3166m  80%   1   0% arangod --server.authentication=true --config /tmp/arangod.conf
  277     0 root     S     1644   0%   2   0% /bin/sh
  284   277 root     R     1580   0%   3   0% top

However, the stats GUI under load shows the values incorrectly hitting a ceiling at 1GB even though this is not reflected by direct docker stats output.
