my customer is trying to get a the maximum IO peak within a specific period of time out of the dfm database. This is the command that he is using:
dfm perf data retrieve -o netapp14 -C volume:total_ops -b "2013-02-19 10:00:00" -e "2013-02-20 10:00:00" -s 3600 -m max
( -m The statistical computation. Valid values are min, max, mean and value_at_percentile.)
But the output seems to make no sense. As you can see he gets about 4400 IO at 14:01:24 and again about 4400 IO at 15:01:24. The max value reported at the end is between those timestamps at 14:16:07. But the value is 1.698.977 which is unrealistically high. Any ideas what goes wrong?
