Reading the description of the Journal alerts: https://docs.cloud.mongodb.com/reference/alerts/#journaling, it is a little confusing as what they mean.

We are not sure if Journaling Write Data Files MB is has to do with the journal or the DB files.

Journaling Commits in Write Lock is may also not be related to journaling.

Changes are needed in the documentation. However, we may also need to do some in the names of the alerts.
