Comment Log – is a way to add explanatory text notes to monitoring responses, based on a specified range of time. There are many different types of comments that can be created based on the circumstances. (As an example, you could create a comment that explains that a specific server error is due to testing of a server and is not an actual error.)
The Comment Log is a simple tool that is helpful for leaving notes for anyone who works on reports.
Depending on your goals, the comments in the Comment Log can be private or public.
Unlike Private comments which are reflected as notes only in online reports, Public comments are also reflected in the XML Feed.
