> 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.
