onStatus method
Judges point — a node's latest reading — against every threshold rule.
Implementation
void onStatus(String nodeId, MetricPoint point) {
for (final rule in rules) {
if (rule.metric == AlertMetric.offline) continue;
_judge(
nodeId: nodeId,
rule: rule,
breached: rule.breachedBy(point),
value: switch (rule.metric) {
AlertMetric.cpu => point.cpuPercent,
AlertMetric.memory => point.memoryPercent,
AlertMetric.disk => point.storagePercent,
AlertMetric.offline => null,
},
);
}
}
