Automatic archiving for instances

Billing

The automatic archiving feature is a paid service. For more information, see Billing of Managed Service for Prometheus.

How it works

When automatic archiving is enabled for a Prometheus instance, the service automatically compresses and moves data to archival storage after its default storage duration expires. Archived data remains queryable, but with reduced query concurrency.

For example, if an instance has a default storage duration of 90 days and an archival storage duration of 60 days:

• Data is retained for up to 150 days. Data older than 150 days is automatically deleted.

• Data from the last 90 days is retained in default storage. Queries for this data are not subject to query concurrency limits.

• Data between 91 and 150 days old is stored in archival storage. Queries for this data are subject to query concurrency limits.

Limitations

• Archival storage duration: You can set the duration to 60, 90, 180, or 365 days.

• Query concurrency limit: Only one concurrent query against archived data is allowed at a time. Requests that exceed this limit time out.

• This feature is only available for Prometheus instances that use the pay-by-observable-data billing mode.
