Alarm Metrics

openYuanrong provides alarm capabilities through metrics. When failures (internal or external components) occur, openYuanrong can export failure information to designated platforms for timely user operations and maintenance.

Metric Name	Metric Meaning	Trigger Condition
yr_proxy_alarm	Scheduler exception.	Reports alarm when heartbeat detection (period is systemTimeout/12, unit is ms, systemTimeout default value is 60000) fails, and no longer detects heartbeat afterwards.
yr_etcd_alarm	etcd exception.	Reports alarm when heartbeat detection (period is metaStoreCheckHealthIntervalMs, unit is ms, default value is 5000) fails, and continues to detect heartbeat afterwards. If detection fails and alarms continuously, clears alarm after recovery.
yr_election_alarm	Leader election exception.	When openYuanrong component (function-master) enables leader election, reports alarm if election fails (currently only supports alarm scenarios using txn leader election mode), clears alarm after recovery.
