To configure the retention policy, navigate to the Graylog interface. Under "System" select "Indices" and click the "Edit" button in the "Default index set".

In the example below, the configuration sets a maximum of 27 indices, with each index retaining 14 days of logs. This setup retains logs for approximately a year (378 days).

We do not recommend keeping more than 14 days of messages per index.

Retention configuration to keep logs for a year

When choosing "Index time" as a rotation policy, you need to define the duration using the ISO8601 Duration standard.

For example, "P7D" means 7 days, "P14D" means 14 days and so on.
