A method, computer program product, and computing system for allocating a portion of a storage system for storing input/output (IO) traces, thus defining an IO trace storage tier. The plurality of IO traces may be stored within the IO trace storage tier. It may be determined whether at least a threshold number of IO traces are stored within the IO trace storage tier. In response to determining that at least the threshold number of IO traces are stored within the IO trace storage tier, at least a portion of the plurality of IO traces may be offloaded to a client computing device.

Described are techniques for request processing. A request may be received from a requester for first data to be returned to the requester. The request may be in accordance with an application programming interface. The first data may include a plurality of objects each including a value for a first property. The request may include a parameter of the application programming interface indicating to return the plurality of objects sorted in accordance with natural ordering based on the first property of each of the plurality of objects. The natural ordering may be performed as the default ordering. With natural ordering, one or more consecutive digits in a string are treated as a single numeric value rather than individual characters. First processing may be performed to service the request and obtain the first data. A response, including the first data, may be generated in accordance with the first processing.

Natural order API calls

Techniques are described that provide for determining health of a system and its components and may include: receiving a hierarchical structure including a plurality of levels of nodes representing the system and components of the system; performing first processing that calculates an overall score denoting health of the system, wherein the overall score is determined in accordance with a plurality of other scores for the components in the system, the plurality of other scores being associated with nodes of the hierarchical structure; and displaying, in a user interface, the overall score.

Natural order in API calls

Examples are generally directed towards disabling features using a feature toggle associated with an application programming interface (API). A server receives an API request including one or more elements. An element is associated with a set of features. If a feature state of every feature within the set of features is an enabled feature state, the element state is an enabled element state and the request is validated. The validated request is executed and a response to the request is returned to the client. If at least one feature state of at least one feature within the set of features is a disabled feature state or a hidden feature state, the element state is a disabled element state and the request is invalided. The invalidated request is rejected and an error message is returned to the client.

Disabling features using feature toggle

Techniques for performing an upgrade may include: receiving notification regarding an occurrence of a trigger event in a system, wherein the trigger event is included in a set of one or more defined trigger events, and wherein the set includes one or more defined time periods; and responsive to receiving the notification, performing first processing including: collecting configuration information describing a current configuration of the system, wherein the configuration information includes data storage device information identifying particular data storage devices in the system, a current version of software on the system, and a current version of firmware for a particular type of data storage device in the system; and performing proactive analysis of the configuration information that determines whether to recommend performing an upgrade to the firmware.

Techniques for performing an upgrade

Examples are generally directed towards managing query responses. A server receives an unspecified property request associated with a resource. The request identifies a resource and omits a property field parameter. A set of instances associated with the resource is identified. An identifier for each instance in the set of instances is identified to form a set of identifiers. The server returns only the set of identifiers to the client as a response to the unspecified property request. On determining the server has received a types-feed request from the client, the server identifies all possible property types for the resource to form a list of all property types. The server returns the list of all property types to the client as a response to the types-feed request.

Returning identifiers in default query responses

Examples are generally directed towards managing paginated data. A server receives a page-to-identifier query from a client. The page-to-identifier query includes an identifier of a selected object instance. The server generates an ordered list of object instances corresponding to at least one ordering criteria paginated into a set of pages. The server identifies a page in the set of pages including the selected instance to form a results page. The results page includes the selected instance. The server returns the results page to the client.
