#       `MONTH` step: yyyy-MM
# Field: `step`
#   represents the accurate time point.
# e.g.
#   if step==HOUR , start=2017-11-08 09, end=2017-11-08 19

#       metrics from the following time points expected
#       2017-11-08 9:00 -> 2017-11-08 19:00
#       there are 11 time points (hours) in the time span.
