Variants

NodeBirth

An Edge Node birth was processed; metrics carry names + datatypes.

Fields

group: String

Group ID.

edge: String

Edge Node ID.

metrics: Vec<Metric>

The birth metrics.

NodeData

Edge Node data (alias-only metrics resolved back to names where possible).

Fields

group: String

Group ID.

edge: String

Edge Node ID.

metrics: Vec<Metric>

The data metrics.

NodeDeath

An Edge Node death: its metrics, and the listed devices, are now stale as of timestamp (epoch ms). The consumer should mark every cached metric for this node and those devices stale.

Fields

group: String

Group ID.

edge: String

Edge Node ID.

timestamp: i64

Death timestamp (the NDEATH payload timestamp, epoch ms).

devices: Vec<String>

Devices that were online under this node and are now stale.

DeviceBirth

A Device birth.

Fields

group: String

Group ID.

edge: String

Edge Node ID.

device: String

Device ID.

metrics: Vec<Metric>

The birth metrics.

DeviceData

Device data (alias-resolved).

Fields

group: String

Group ID.

edge: String

Edge Node ID.

device: String

Device ID.

metrics: Vec<Metric>

The data metrics.

DeviceDeath

A Device death: its metrics are now stale as of timestamp (the DDEATH payload timestamp, epoch ms).

Fields

group: String

Group ID.

edge: String

Edge Node ID.

device: String

Device ID.

timestamp: i64

Death timestamp (the DDEATH payload timestamp, epoch ms).

RebirthRequested

The host requested a rebirth (published an NCMD) for an Edge Node.

Fields

group: String

Group ID.

edge: String

Edge Node ID.

Ignored

A message that did not require action (own command echo, foreign/own STATE, a stale NDEATH, or a debounced rebirth).
