Monitor progress of cluster to cluster sync?

Hey All,

I’ve set up 2 replica sets of mongodb (3 nodes each) in containers. I’m able to mongosync them, but I was wondering if there’s any way I can monitor the progress of the cluster-to-cluster sync? I know there is the progress endpoint in the API (/api/v1/progress), but I am hoping to see how long it took for the synchronization to complete. Specifically, I want to see the difference for syncing data which is 5Mb, 10Mb, 20Mb, …
My company has 2 data centers far from each other and I need to give some metrics to determine if mongosync is suitable.
