Struct BackupMetrics 

pub struct BackupMetrics {
    pub error_count: Arc<AtomicU64>,
    pub last_success_ts: Arc<AtomicU64>,
    pub lag_s: Arc<AtomicU64>,
    pub healthy: Arc<AtomicBool>,
    pub lease_held: Arc<AtomicBool>,
}

The continuous-backup counters GET /metrics reports as mushroomdb_backup_*. The serve loop registers them with register_backup_metrics when backup is configured; without that, no backup series is emitted at all (absent, not zero, so an alert on mushroomdb_backup_lag_seconds cannot be satisfied by a store that was never backed up).

Fields

error_count: Arc<AtomicU64>

Failed backup steps since start.

last_success_ts: Arc<AtomicU64>

Unix seconds of the last moment everything durable was shipped; 0 before the first.

lag_s: Arc<AtomicU64>

Seconds the oldest durable, unshipped WAL byte has waited.

healthy: Arc<AtomicBool>

Whether the worker reports itself healthy.

lease_held: Arc<AtomicBool>

Whether the worker holds the bucket lease right now.
