memory property
Memory is total system RAM in BYTES — not GB, and not what is free right now (fleetMetrics carries that). Absent when the source reports no RAM figure.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
int? memory;
