"""
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.
