The Little IoT Agent (liota)
summary
Liota is a portable Python agent that claims to turn any gateway into a managed telemetry source; it ships BSD-2 licensed and already implements two transports (sockets, websockets) and a data‑center adapter for vRealize Ops Manager. The code models device, device_comms, edge_system, metric and DCC, uses a package manager patterned on OSGi, and collects metrics via user-defined methods (UDMs) into event/collect/send queues. It runs on the varied gateways shown at VMworld, was exercised in a hackathon with a robot and demo apps, and successfully pushes fixes and time‑series to backend DCCs.
