The problem ins persistent in the default graphs of Ganglia. For example check
these graph for "Network" for the last "day" and last "year" in the attached
images. You will notice that in the "last day" maximum there was a peak of
about 70 Mb/ps while the graph for the "last year" does not even scale beyond
less than 10 Mb and the peak indicated is about 8 Mb/ps. Ofcourse, the MAX
value should not reduce over the year. Anyone who could explain the
observation? Thanks a lot.
Thanks,
Neel

>Hi, I am plotting metrics by using gmetad. I am also displaying the MAX,
MIN, AVERAGE and LAST values on the ganglia graph. I realised it today, that
the MAX value is correct if you watch the graph for the last hour. However, It
is incorrect for any other time range. For eg. If in my last hour the MAX value
is 2900, however, when see the last day, week or year the MAX value can be
shown as lesser also. It seems ganglia simply gives the average of the MAX
values over time ranges beyond last hour. Could anyone please provide me a
workaround or a fix? I would be really grateful.
