How to determine SQL Server database transaction log usage

One crucial aspect of all databases is the transaction log. The transaction log is used to write all transactions prior to committing the data to the data file.

So how to you determine how much of the transaction log is being used and what portions are being used?

How to Read a Transaction Log Backup

This function is undocumented, so you should use care when using this function in a production environment.
