SparkLogs event fields

Event kind, topic, reason and structured data, with the classification assigned by the Data Feed Pack.

Field	Type	Unit	Meaning
sparklogs.kind	string		The event category that selects its row contract and downstream handling. Producers define additive values; consumers must not infer a closed vocabulary from this field.
sparklogs.topic	string		Which state topic the row belongs to, and the namespace its readings sit in under sparklogs.data.
sparklogs.reason	string		A globally unique reason code explaining why the event was emitted or how it was classified.
sparklogs.instance	string		The subject ID, prefixed by its type. Absent for conditions about the whole device.
sparklogs.open_monitors_count	integer	count	Number of open conditions for this topic. On a multipart inventory, carried on the first part.
sparklogs.window_partial	bool		The measurement window behind these readings was not fully populated, so a rate or a percentile over it rests on fewer samples than usual. Absent when the window was whole.
sparklogs.data	object		The readings, under sparklogs.data.<topic>. A table topic writes an array of row objects; a host-scoped topic writes one flat object. An inventory and a delta write the same path, so one predicate finds a value whichever way the evidence arrived.
sparklogs.class	string		The event's temporal role, such as a notable condition, recovery, ending, or context.
