Replication

Replica-set topology, oplog, lag trend, heartbeats, and elections

Requires a selected live connection. Auto-refresh ~5s.

  • Replica-set topology (members, lag, priority/votes)
  • Oplog window (size, fill, growth)
  • Lag trend sparkline (session samples since connect, ~10m window, no backfill)
  • Heartbeats (ping edges from this node)
  • Recent elections / state changes from server getLog RAM buffer (not a fixed multi-day history)
  • Default write concern (majority wait is not exposed read-only → shown as n/a)
