Monitoring Registry

This page is for future nodewatcher version currently in development.

The monitoring registry uses the same modular registry framework as the configuration registry. Its registration point is node.monitoring. In contrast to configuration its purpuse is storage of per-node information that is obtained via live reports from nodes and routing daemons. The registry framework is reused because monitoring must also be as modular and extensible as possible.

All registry item class names in this schema must end in Monitor.
