This page describes how the Metrics powered by Grail - Retain DPS capability is consumed and billed. For an overview of the capability, including its main features, see Metrics powered by Grail - Retain.
Retained data is the amount of data saved to storage after data parsing, enrichment, transformation, and filtering but before compression. The unit of measure for Metrics - Retain is the gibibyte-day (GiB-day).
15 months (462 days) of 1-minute granularity is included with Metrics powered by Grail. Metrics that you choose to retain beyond that period are charged.
Apply the following calculation to determine your consumption for the Retain data-usage dimension:
(number of GiB-days) × (retention period in days) × (GiB-day price as per your rate card) × (number of days that data is stored in excess of 462 days) = consumption in your local currency
Following the Ingest & Process step in Metrics - Ingest & Process, your enriched data is retained on an on-going basis. If you ingest 1.5 billion data points per day, 9 GiB of data might be added daily to your storage. Retain includes 15 months (462 days) of storage in the default retention period.
Assuming you don't change the default retention period, metric data will be retained for 15 months (462 days) and there will be no billable Retain usage.
If you increase the retention period to 5 years (1,832 days), the monthly consumption for retain (after 1,832 days) is calculated as follows:
9 GiB9 GiB * (1,832 days - 462 included days) = 12,330 GiB12,330 GiB * (Retain price as per your rate card) = Cost12,330 GiB * 30 days * (Retain price as per your rate card) = Cost
