Abstract: Systems and methods for invalidating and regenerating pages. In one embodiment, a method can include detecting content changes in a content database including various objects. The method can include causing an invalidation generator to generate an invalidation based on the modification and communicating the invalidation to a dependency manager. A cache manager can be notified that pages in a cache might be invalidated based on the modification via a page invalidation notice. In one embodiment, a method can include receiving a page invalidation notice and sending a page regeneration request to a page generator. The method can include regenerating the cached page. The method can include forwarding the regenerated page to the cache manager replacing the cached page with the regenerated page. In one embodiment, a method can include invalidating a cached page based on a content modification and regenerating pages which might depend on the modified content.

Abstract: An SLO (service level objective) is represented by a model that includes nodes that represent elements in a system that are used to fulfill the SLO and information that represents dependencies between the elements. Telemetry information is received describing a condition of an element in the system. The telemetry information can be applied to a particular procedure associated with a particular node in the model to determine if there is a problem associated with the element represented by the particular node. At least a portion of the telemetry information is applied to procedures to determine problem cause information describing which elements have problems relating to the SLO. A relative contribution of elements to a problem associated with the SLO is determined by analyzing the problem cause information and the dependencies between the elements.
