feat(place/driver_health): report driver process health across the cluster - #627
Merged
Conversation
…uster Checks every driver process on every core node and exposes a name, running state and check timestamp for each, so cluster health can be inspected in backoffice or exported to InfluxDB. Core nodes are read from the `core` service registration, the same one Proxy::RemoteDriver uses to route module requests, then each node is asked about its own driver processes over core's internal API. No API key or request to an external PlaceOS instance is involved. A driver process that isn't using any memory isn't running. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…iver name InfluxDB can't aggregate boolean fields (mean, sum) without mapping them first, so `running` is now an Int32 of 1 or 0. The `drivers` status uses the complex metric hint with `name` as a tag key so each driver process is its own series rather than a field to pivot on.

…mit, tag by hostname Driver executables are named `<source>_<commit>_<arch>` by the build service. DriverState now carries `hostname`, `driver` and `commit` as their own fields (architecture is dropped) and `name` is `<hostname>.<driver>` so it tags cleanly in InfluxDB across builds. `hostname` is also exposed as a tag key.
