TR Reliability

Tunnel Routing (TR) is FortiWAN’s important function used to construct intranets between multiple LANs anywhere in the world. Tunnel Routing also boosts performance by supporting link aggregation and fault tolerance over multiple links for services such as VPN and live video streaming. A Tunnel Group represents the configuration of Tunnel Routing on FortiWAN between two specific sites; it includes related internal IP addresses of both sites and routing policies between sites (See “Tunnel Routing”).

The TR Reliability report shows the statistics on the failures happened on FortiWAN’s TR links. Please reference FortiWAN User Manual for more information about Tunnel Routing.

• Note: A “▲” or “▼” is shown aside the column header while the column is selected as primary sorting, e.g. Group ▲. The sorting order will be switched by clicking on the same column header.

WAN Status

FortiWAN supports various numbers of WAN links, for example, FortiWAN 700 supports 25 WAN links, FortiWAN 5000 and FortiWAN 6000 support 50 WAN links. The WAN Status report shows the statuses on every FortiWAN’s WAN link. The various statuses are defined as below.

• OK: WAN link is enabled, configured and connected physically. l Fail: WAN link is enabled and configured, but disconnected. l Disable: WAN link is not enabled from FortiWAN Web UI.

Export reports and send reports through email (See “Export and Email”). WAN Traffic Distribution

• Traffic distributions of every WAN links are presented individually. l X axis: Time between 00:00 to 23:59 (of a selected date). Days from start to end if Date Range specified (max 90 days). l Y axis: Bandwidth in Kbps or Mbps. l Green indicates inbound data rate. l Blue indicates outbound data rate.

Clicking on Both, In or Out buttons at the right upper corner of the graph allows you to see bandwidth distribution in different directions:

Session

The Session report shows the distribution of sessions (connections) by the date range defined. Your FortiWAN model is rated by the number of simultaneous connections it can process (among other things as noted above). This report will help you determine if you are using the correct FortiWAN model for the number of connections in use by your users.

CPU

The CPU report shows the distribution of CPU usage of FortiWAN by the date range defined. CPU usage is a measure of how much traffic is being managed or how much services the FortiWAN is required to do on that traffic. Sustained usage near 80% is a good indicator that a larger FortiWAN model is required to handle the required traffic and services load. Use this chart to compare your target maximum usage with the actual usage over time.

Device Status

The Device Status report shows the top-level view of the analysis of the traffic flowing through FortiWAN. Device Status includes 9 categories showing the average data rate through FortiWAN, the number of sessions (connections) in use, the status of WAN links and TR connections and FortiWAN hardware statistics.

Dashboard

The Dashboard is a palette containing the chart-based summary of FortoiWAN’s system information and hardware states. Bandwidth usage, CPU, memory and HD storage usages, concurrent sessions, WAN link states, the peer information in HA deployment, FortiWAN firmware version, model and bandwidth capability are summarized here for your reference at a glance. For long-term and deep look inside the items, individual report page gives the details.

The statistics of bandwidth, session , CPU and memory usages on the dashboard come from the Reports database, just like all the other report pages, are counted every 5 minutes. The data of WAN link state, peer information and hard disk on the dashboard is updated instantly when it is refreshed every time. You can set an appropriate refresh time interval for the dashboard (See “Dashboard Page Refresh Time”).

System Information

The System Information panel located at the upper-right corner gives the information of current FortiWAN firmware version, model and bandwidth capability.

Total Bandwidth

The line chart in Total Bandwidth panel displays the distribution of traffic (inbound and outbound) passed through FortiWAN over the past one hour. The horizontal (x) axis is graduated in minutes, and the vertical (y) axis is graduated in bps (average) to indicate the bandwidth usage. The distributions of inbound and outbound traffic are marked with different color. Moving the mouse to any point of the distribution will display the exact traffic generated at the time. Moving the mouse over the line chart and clicking it will redirect you to the Bandwidth page (See “Bandwidth”).

The bar chart aside the distribution displays the percentage of the traffic generated in the past five minutes. The bandwidth capability (denominator) used to calculate the percentage is the sum of the transfer speed (down stream and up stream) of every enabled WAN link (defined in Network Setting, see “Configuring your WAN”). For example, if there are two enabled WAN links defined with 10 Mbps and 20 Mbps down stream, and 5 Mbps and 10 Mbps up stream respectively, the bandwidth capability used to calculate the percentage will be 45 Mbps. This bandwidth capability changes as a WAN link being enabled or disabled. The bars are marked with different color for inbound and outbound traffic. 50% and 80% are the two waterlines used in the bar chart to alert administrators to the exceedance. The bar is marked with green if the percentage of bandwidth usage is less than 50%, with orange if it is between 50% an 80%, and with red if it exceeds 80%.

Session

The line chart in Session panel displays the distribution of sessions amount that FortiWAN processed over the past one hour. The horizontal (x) axis is graduated in minutes, and the vertical (y) axis is graduated in 1’s to indicate the session amount. Moving the mouse to any point of the distribution will display the exact session amount generated at the time. Moving the mouse over the line chart and clicking it will redirect you to the Session page (See “Session”).

The bar chart aside the distribution displays the percentage of the sessions amount generated in the past five minutes. The concurrent session capability (denominator) used to calculate the percentage depends on your FortiWAN model. 50% and 80% are the two waterlines used in the bar chart to alert administrators to the exceedance. The bar is marked with green if the percentage of session amount is less than 50%, with orange if it is between 50% an 80%, and with red if it exceeds 80%.

CPU

The line chart in CPU panel displays the distribution of FortiWAN’s CPU usage over the past one hour. The horizontal (x) axis is graduated in minutes, and the vertical (y) axis is graduated in % to indicate the CPU usage.

Moving the mouse to any point of the distribution will display the exact percentage of CPU used at the time. Moving the mouse over the line chart and clicking it will redirect you to the CPU page (See “CPU”).

The bar chart aside the distribution displays the percentage of CPU usage in the past five minutes. 50% and 80% are the two waterlines used in the bar chart to alert administrators to the exceedance. The bar is marked with green if the CPU usage is less than 50%, with orange if it is between 50% an 80%, and with red if it exceeds 80%.

Memory

The line chart in Memory panel displays the distribution of FortiWAN’s memory usage over the past one hour. The horizontal (x) axis is graduated in minutes, and the vertical (y) axis is graduated in % to indicate the memory usage. Moving the mouse to any point of the distribution will display the exact memory usage at the time.

The bar chart aside the distribution displays the percentage of memory usage in the past five minutes. 50% and 80% are the two waterlines used in the bar chart to alert administrators to the exceedance. The bar is marked with green if the memory usage is less than 50%, with orange if it is between 50% an 80%, and with red if it exceeds 80%.

WAN Link State

The WAN Link State panel displays the state of every FortiWAN’s WAN link. The number of WAN links displayed here varies depending on the model of the FortiWAN unit. Taking FortiWAN 200B for example, it supports 25 WAN link connections in maximum (See “WAN link and WAN port”). Each WAN link is color-coded to indicate its state.

Peer Information

Peer information displays the state of slave unit for a HA deployment (See “FortiWAN in HA (High Availability) Mode”).

Hard Disk

FortiWAN’s Reports functions with a database system and necessary log data stored in the built-in hard disk. Disk space is being consumed by increasing report database. Once the disk space is ran out, Reports will fail to continue log processing. Disk usage statistics viewer here reports the disk space usage (%), so that an appropriate cleanup (See “Disk Space Control” and “Reports Database Tool”) can be took to low disk space.
