The committer name is determined by your SCM tool (assuming your
script that posts to Lighthouse sets it properly). For git, you
would git log commit a specific commit ID. The
"author" of the commit is your git name.
In the example below, the git committer name is "rick".
$ git log commit 3d1902ec686fef44e603bde8501b13c5feb4ec41
