Hi, thank you for your interest.
I'm running the following commands (for example) in DFM, to pull out specific performance statistics:
dfm perf data retrieve -o netapp001-02:netapp001_02_data01 -C aggregate:total_transfers -b "2015-12-18 13:00:00" -e "2015-12-25 14:00:00" -m mean
dfm perf data retrieve -o netapp001-02:netapp001_02_data01 -C aggregate:total_transfers -b "2015-12-03 13:00:00" -e "2015-12-03 14:00:00" -m min
dfm perf data retrieve -o netapp001-02:netapp001_02_data01 -C aggregate:total_transfers -b "2015-12-03 13:00:00" -e "2015-12-03 14:00:00" -m max
dfm perf data retrieve -o netapp001-02:netapp001_02_data01 -C aggregate:total_transfers -b "2015-12-03 13:00:00" -e "2015-12-03 14:00:00" -m value_at_percentile -P 95
OPM doesn't seem to have this functionality. I get close with Graphite, but only in a pictorial fashion.
