"""Cron script to generate usage notifications for volumes existing during
|
|
the audit period.
|
|
|
|
Together with the notifications generated by volumes
|
|
create/delete/resize, over that time period, this allows an external
|
|
system consuming usage notification feeds to calculate volume usage
|
|
for each tenant.
|
|
|
|
Time periods are specified as 'hour', 'month', 'day' or 'year'
|
|
|
|
hour = previous hour. If run at 9:07am, will generate usage for 8-9am.
|
|
month = previous month. If the script is run April 1, it will generate
|
|
usages for March 1 through March 31.
|
|
day = previous day. if run on July 4th, it generates usages for July 3rd.
|
|
year = previous year. If run on Jan 1, it generates usages for
|
|
Jan 1 through Dec 31 of the previous year.
