The Periodic tab allows you to schedule periodic reports that will automatically be generated for you. Each report will be saved in the specified S3 bucket. To save the report in multiple S3 buckets, simply create another periodic report. Currently, you can create up to 10 periodic reports.
Report > ServerTemplates Usage > Index > Periodic tab
Frequency - Specify how often the report should be generated (e.g. Daily or Monthly). The reports are slightly different. Daily reports will group usage by day (multiple rows per instance), while monthly reports group usage by instance for the whole month (single row per instance).
S3 Bucket - Select the S3 bucket where the usage report (.csv) will be stored.
Report Name - Name of the usage report.
Email Notification (optional) - Provide a comma-separated list of email addresses that will receive notifications when the report becomes available. Note that this is an email notification only, the report is not attached to the email. You must browse the S3 bucket to gain access to the report data.
