Sometimes you expect to see certain data in VMware Tanzu Observability (formerly known as VMware Aria Operations for Applications) but, for some reason, it doesn't show up! This can be a frustrating and confusing experience, especially when you urgently need the data. Tanzu Observability does not delete data - the [retention period](terms_of_service.html#data-retention) is 18 months for persistent metrics and 28 days for ephemeral metrics.
