Path and cadence optimization for efficient data collection from devices

Abstract

Presented herein are embodiments for collecting and sharing telemetry data. A plurality of requests are received, from one or more applications, for telemetry data that is stored in a hierarchical tree representation comprising a plurality of nodes, wherein the telemetry data indicates an operational status and performance of a device, and wherein each request includes a cadence indicating a timespan at which the request repeats, and a path in the hierarchical tree where a requested portion of the telemetry data is stored. Processing the requests produces an optimized set of requests by merging any two or more requests whose paths indicate portions of data that share a common parent node in the hierarchical tree, wherein a merged request is assigned a cadence corresponding to a shortest cadence among the two or more requests. The hierarchical tree is polled using the optimized set of requests to satisfy the received requests.
