+ <summary>
+ Chrome OS network metric sampling the time spent using VPN to transport
+ data. These data are mostly useful when summed and compared to TimeOnline
+ for other network technologies (e.g. WiFi vs Cellular). A sample is emitted
+ every time the system transitions from primary connectivity through a VPN to
+ some other type of connectivity. The value of the sample is the time delta
+ in seconds from the instant the system transitioned to VPN connectivity.
