Total number of displayed paths, indicated by a decimal
number.
Number of online paths from within the displayed paths,
indicated by a decimal number. When the value of Paths

value of OnlinePaths is less than that of Paths, some
paths are offline. In this case, you should check the offline
paths and take appropriate action for any paths that have
an error status.
