Online Event Data Usage enables you to see a summarized view of online event data usage. This view enable you to manage storage more effectively by writing appropriate event dropping policies or online event retention policies.
The Online Event Data Usage is displayed in tree view under ADMIN > Settings > Database > Online Data grouped by the year and dates for NFS/Local storage. For Elasticsearch-based deployments, if the storage is set per Organization, the usage is displayed specific to each Organization grouped by year and dates. You can drill-down from the year to view the usage for any specific date.
