Techniques perform sample selection. Such techniques involve: in response to receiving a query time range for samples input by a user, obtaining a plurality of groups of samples from a sample set, each group of samples being collected within a corresponding time range. Such techniques further involve: determining a relationship between the query time range and time ranges corresponding to the plurality of groups of samples. Such techniques further involve: determining, based on the determined relation and from the plurality of groups of samples, a group of samples with a corresponding time range matching the query time range. Accordingly, these sets of samples may be presented accurately and efficiently to the user in a selective manner.

An aspect includes identifying one or more dependencies, via a feature toggle component of an application programming interface (API), with respect to features associated with a set of resources. An aspect also includes populating identified dependencies within a metadata table corresponding to the API and defining a multi-level access control feature for the resource. The multi-level access control includes a top level that identifies the resource, and a mid level that identifies a first set of properties for the resource. An aspect further includes populating fields in the metadata table with the first set of properties and a corresponding mid-level indicator, and enabling access to the resource at varying levels of granularity based on the identified dependencies in the metadata table for the resource and the mid level-indicator for the first set of properties.

Techniques for request processing may include: receiving, at a data storage system, a plurality of requests from one or more clients, wherein the plurality of requests are in accordance with an application programming interface (API); collecting usage information regarding the plurality of requests; and periodically transmitting portions of the usage information to a data center. The usage information may include usage statistics regarding usage aspects of the API with respect to different types or classes of components in the data storage system. The usage information may be further analyzed for any suitable purpose such as to prioritize and identify existing features, services and/or commands for further development and improvement; identify unused or infrequently used features, commands, and/or parameters; and identify potential user interface enhancement.

Telemetry service

Techniques for customizing a software product may include receiving customization information describing customizations to the software product requested by a user; submitting a request including the customization information to a web service; and responsive to receiving the request, performing processing comprising: creating, by the web service, a new job to generated a customized version of the software product in accordance with the customization information of the request; automatically generating at least one customized file in accordance with the customization information; generating the customized version of the software product including the at least one customized file; and testing the customized version of the software product.
