syncoid: statistics?

[apiening]

Not an issue, just a question or possible feature suggestion: Are there any statistics provided by syncoid?

I know that it is possible to monitor snapshots with sanoid, which is working well and more important.

But I'm interested in transfer time, amount of data and success of the transfer per filesystem. It seems to be possible to get the estimated stream size with a dry-run: https://docs.oracle.com/cd/E36784_01/html/E36835/gnheq.html The idea solution I think of would be an option like --statistics-file which writes a CSV file with the content starttime, endtime, duration, streamsize, success.

This would enable useful monitoring options and statistics in combination with monitoring tools like zabbix for example.
