>
> Some checkpoint metrics use the latest stats snapshot to get the returned
> metric value. These snapshots are only updated when the {{WebRuntimeMonitor}}
> actually requests some stats (web UI or REST API).
> In practice, this means that these metrics are only updated when users are
> browsing the web UI.
> Instead of relying on the latest snapshot, the checkpoint metrics should be
> directly updated via the completion callbacks.
