Monitoring > Bandwidth > Tunnels > Pie Charts
The Tunnel Bandwidth Pie Charts show the proportion of bytes a tunnel consumes on inbound and outbound LAN and WAN.
Hovering over the charts and the legends reveals additional information.
The WAN charts identify the percentage of the bandwidth the appliance saved by optimizing the traffic.
NOTE: For one-day statistics, Orchestrator saves statistics at midnight (UTC time) for the previous day. Therefore, clicking 1d displays data for the entire day preceding midnight (UTC). For example, if you do this five hours after midnight (UTC), only recently-generated statistics belonging to the day preceding midnight (UTC) will be displayed. The last five hours will not be reflected in the pie charts. To display statistics for the last 24 hours, click Custom, select Hour for Granularity, and then specify the exact 24-hour time range.
