Event data retention and storage limits

You can modify settings to determine how event data is handled on your cluster.

By default, data related to resolved event groups is retained indefinitely. You can set a retention limit to make the system automatically delete resolved event group data after a certain number of days.

You can also limit the amount of memory that event data can occupy on your cluster. By default, the limit is 1 megabyte of memory for every 1 terabyte of total memory on the cluster. You can adjust this limit to be between 1 and 100 megabytes of memory. For smaller clusters, the minimum amount of memory that will be set aside is 1 gigabyte.

When your cluster reaches a storage limit, the system will begin deleting the oldest event group data to accommodate new data.
