How long is the metadata kept

Information is provided about the retention periods for the metadata that is collected to provide storage services and to improve storage services.

As metadata about monitored devices is collected, the aggregation level of that metadata changes. For configuration, status, and capacity metadata, over a two years period, the aggregation levels of the metadata change from sample to hourly, then hourly to daily based on the age of the metadata. For performance metadata, over a one year period, the aggregation levels change from sample, to hourly, to daily based on the age of the performance metadata. In effect, a more granular view of new metadata is provided and a less granular view of aged metadata is provided.

The following table lists the aggregation levels for asset, configuration, and capacity metadata based on the age of the data that is collected:

Table 1. Asset, configuration, and capacity metadata
Aggregation level	Metadata age
Sample	2 weeks
Hourly	4 weeks
Daily	2 years

Capacity data is collected via the device probes: full probe, advanced mini probes (for DS8000 systems), and mini probes. The full probe is typically scheduled to run once every 24 hours, the advance mini probes run every hour, and mini probes are event-based. For example, as a volume's capacity changes over time, there may be more than one data point per day which is aggregated into the capacity data.

Sample: Data that is collected directly from the device is stored at sample granularity, and then aggregated to hourly and daily aggregation levels.
Hourly: The sample data collected within the hour is aggregated as an hourly data value. If no sample data is collected in an hour, the hourly data does not have a value for that particular hour.
Daily: The sample and hourly data points of the day are aggregated into the daily data value.

The following table lists the aggregation levels for performance metadata based on the age of the data that is collected:

Table 2. Performance metadata
Aggregation level	Metadata age
Sample	2 weeks
Hourly	4 weeks
Daily	1 year

Based on the collection date, metadata is retained for up to two years.

Note: If you subscribe to IBM Storage Insights Pro and cancel your subscription, you'll still be able to use IBM Storage Insights. The metadata from IBM Storage Insights Pro is retained.

How long are diagnostic data packages kept

Typically, diagnostic data is automatically deleted from IBM® Enhanced Customer Data Repository (ECuRep) 30 days after the ticket is closed. For information about the retention of data in ECuRep, see the External link icon IBM terms of use for Exchanging diagnostic data with IBM.

Blue Diamond Enhanced Secure Support uses a secure, dedicated portal for diagnostic data packages. For more information about diagnostic data and Blue Diamond, contact the Blue Diamond team at the External link icon Blue Diamond registration page.
