Sunbird Obsrv comprises several pluggable tools and microservies that come together to enable observability features on any platform/solution. This includes the ability to capture granular events via telemetry, create measures, and observe various events/actions carried out by the system/users/devices (like IoT devices) on any platform/solution. Sunbird Obsrv can be utilized as an independent building block by adopters or as part of a system that employs other Sunbird building blocks. Sunbird Obsrv comes with a set of microservices, APIs, and some utility SDKs to make it easy for adopters to rapidly enable powerful data processing and aggregation infrastructure to process telemetry data, validate telemetry stream data, as well as aggregate and generate actionable insights via APIs. It also has built-in open data cataloging and publishing capability. It is built keeping extensibility in mind, so that adopters have the flexibility to adapt the telemetry and tools to their specific use-cases.
