picarro.sam.controller.Controller/watch

Server stream of picarro.sam.controller.Signal. This is a "mapping signal": each message carries mapping_action (MAP_ADDITION | MAP_UPDATE | MAP_REMOVAL) and mapping_key (the analyzer identity, e.g. "Picarro_8008-AMSADS3008"). analyzer_health is cached server-side and re-emitted to new watchers.

About AsyncAPI

The AsyncAPI specification describes event-driven APIs the way OpenAPI describes request/response APIs. A channel is the named pipe — a webhook URL, a Kafka topic, a WebSocket route, an MQTT subject — that producers and consumers publish or subscribe to. Each channel carries one or more messages with structured payloads, and an operation declares whether a given party sends or receives on that channel.

Browse every event-driven channel on the APIs.io network or compare with the broader Agent Skill and MCP server surfaces of the same providers.
