on GitHub

1.10.0 (2026-10-05)

Features Added

• Added the Azure.Monitor.OpenTelemetry.Exporter.StorageSubDirectory AppContext value, settable with AppContext.SetData or a runtimeconfig.json configProperty, so that the processes or entry points of one application can share a persistent storage directory. By default the directory name is derived from the process name and AppContext.BaseDirectory, which splits storage when components of one application differ in either, and a component that runs rarely never drains its backlog. When set, the value replaces those two inputs; the instrumentation key and user name still contribute, so different users and resources stay isolated. Behaviour is unchanged when the value is not set.

Bugs Fixed

• SDK statistics sent to the Microsoft OpenTelemetry distro's configured ingestion endpoint (the Azure.Monitor.OpenTelemetry.Exporter.RouteSdkStatsToDistroEndpoint AppContext switch) now carry the same region-matched SDK statistics instrumentation key as the existing SDK statistics endpoint, instead of an all-zero placeholder. Only the destination differs on the distro path.
