Step 2. Why Deploying a Monitoring Solution Before A Fortinet SD-WAN Migration is Crucial for Network Performance
Deploying a monitoring solution before migrating to Fortinet SD-WAN is critical for comparing network performance before and after the migration. This allows you to track any changes in performance and identify any issues that may arise during or after the migration process.
At Obkio, we monitor network performance using synthetic UDP traffic from Monitoring Agents deployed in key network locations.
To monitor a Fortinet SD-WAN migration, we recommend deploying Monitoring Agents in your local network and between network locations, such as remote offices and your company's headquarters, data centers, or clouds.
In the example above, a branch office migrated from a dedicated low-bandwidth MPLS connection to an SD-WAN service with two broadband connections. The migration occurred in the middle of the graph (around 18:20).
A few minutes later, around 19:00, the SD-WAN service switched from the primary ISP to the secondary ISP due to high packet loss for about 15 minutes. The graph shows just a little bit of packet loss during the failover because it took a few seconds for the SD-WAN appliance to failover.
Don't leave your Fortinet SD-WAN migration to chance. Deploy a monitoring solution before your migration to ensure maximum network performance and reliability. Contact Obkio today to learn more about our solutions and how we can help you optimize your Fortinet SD-WAN network.
After migrating to your new Fortinet SD-WAN service, network testing is crucial to ensure optimal network performance. But to set up SD-WAN monitoring, you need to understand the design of your network to adapt it to your monitoring setup.
Your SD-WAN network architecture consists of various components that can cause performance issues, including the Underlay, Overlay, LAN and Last mile.
Additionally, Firewall as a Service (FWaaS) can create additional communication paths that may require opening support tickets with your Service Provider.
It's essential to have a comprehensive understanding of your Fortinet SD-WAN network's anatomy to identify potential performance issues and deploy an effective monitoring solution that covers all network components.
The image below displays a Fortinet SD-WAN network site communicating with a Data Center, Head Office, or IaaS.
In an SD-WAN Architecture, SD-WAN issues can come from many different places:
- The Internet
- Internet Local Loop
- Internet Provider’s Edge Router
- ISP Backbone
- ISP Peering Point
- Internet VPN IPSec between the site and ZScaler (Firewall As A Service)
- IPsec Tunnel from one site to another
- The LAN
- SD-WAN Edge
- Core & Distribution Switches
- Access Switches
The Last Mile
- 80% of companies using SD-WAN experience performance issues on the last mile of the network. The last mile generally has the lowest speeds, the least route diversity and the most single points of failure.
Firewall As A Service (FWaaS)
- If your business also has Firewall As A Service (FWaaS), you’ll need to open a support ticket with your Service Provider if the problem is located on their side.
To fully deploy your SD-WAN monitoring solution, it is essential to install Network Monitoring Agents in the customer LAN, behind the Fortinet SD-WAN appliance. This allows for end-user perspective monitoring, providing a comprehensive view of the network's performance.
By monitoring network performance from the end-user perspective, you can ensure that critical business applications are performing optimally and identify any issues that may affect user experience.
With Network Monitoring Agents in place, you can proactively identify and troubleshoot performance issues, improving overall network efficiency and uptime.
This is the setup we recommend:
- 1 Local Agent per network location (data centers, remote offices etc.)
- 3 Public Monitoring Agents to monitor the Internet
With this setup, you’ll also have visibility of:
- ISP #1 connection
- ISP #2 connection
- The End-User (load balanced between the connection using the SD-WAN algorithm)
- The SASE Service
Once the Monitoring Agents are deployed, they start creating Monitoring Sessions that use synthetic UDP traffic to monitor each network path. This allows the Agents to measure network metrics, such as latency, jitter, and packet loss, and identify any issues that may arise.
If the Agents detect any performance issues, they will raise alerts to notify network administrators, who can then take action to address the problem.
With SD-WAN monitoring tools, businesses can proactively identify and resolve network issues before they become a major problem, ensuring maximum network uptime and efficiency.
In order to effectively monitor the performance of your SD-WAN network, it's important to track both end-user perspective and underlay connections. This will allow you to compare actual performance against the SLA or promises made by your SD-WAN vendors.
To achieve this, you can set up three monitoring sessions between a local Monitoring Agent behind the SD-WAN appliance and three remote Monitoring Agents located in the same area, such as a cloud, data center, or head office.
With this monitoring setup, businesses can gain valuable insights into the performance of their SD-WAN network. By configuring three monitoring sessions between a local Monitoring Agent behind the SD-WAN appliance and three remote Monitoring Agents located at the same location (such as a cloud, data center, or head office), network administrators can monitor performance from multiple perspectives.
The top graph in the monitoring sessions represents the performance as seen by the end-user, load balanced between the connections using the SD-WAN algorithm. The middle graph shows the performance of the ISP A connection, while the bottom graph shows the performance of the ISP B connection.
By monitoring network performance from multiple perspectives, businesses can identify performance issues and troubleshoot them more effectively. This allows network administrators to take proactive measures to ensure that the network is operating optimally, improving overall network efficiency and uptime.
This type of setup is commonly used by businesses that rely on Fortinet SD-WAN technologies. By monitoring both the end-user perspective and individual ISP connections, they can accurately measure actual network performance and detect any issues that may arise.

For instance, in the below screenshot, Branch 3 is identified as the most affected location as all of its network sessions are experiencing performance issues.
Switch to Dashboard View to Identify and Troubleshoot Network Issues
To gain more insight into the exact nature and pattern of performance issues, switch to the Dashboard View, which displays all key network metrics for a specific branch on a single page. This allows you to compare information from all deployed Monitoring Agents and identify the root cause of issues.
In the screenshot below, you can see a sample Dashboard for Branch 3, which features various performance graphs that can be customized to display information for different time frames.
The selected view shows performance metrics over the last 8 hours.
Now that we have discussed the importance of monitoring SD-WAN performance from multiple perspectives, let's take a closer look at the Dashboard View provided by Obkio's SD-WAN monitoring solution.
In this view, network administrators can access a wealth of information about the performance of their SD-WAN network, including graphs for UDP monitoring session performance, SNMP polling on the SD-WAN Edge Equipment, and application performance metrics.
- Column 1 displays the UDP monitoring session performance from the Branch 3 Monitoring Agent towards the SD-WAN user experience Monitoring Agents. The first graph depicts the Internet SD-WAN user experience, while the 2 bottom graphs show the experience of the Internet connections (ISP 1 & ISP 2).
- Column 2 represents SNMP Polling (Device Monitoring) on the SD-WAN Edge Equipment. Obkio performs SNMP monitoring on the Monitoring Agent and presents metrics for CPU Usage and Bandwidth Usage in the graphs below.
- Column 3 displays performance metrics for Zoom and Microsoft Teams, which are also provided by Obkio. It presents HTTP Application Performance and VoIP Quality metrics.
Now that we have identified that there is poor performance affecting all the traffic and both ISPs are being affected, the next step is to find the cause.
Upon analyzing the information above, it is apparent that there is a significant performance issue that is impacting all traffic, affecting both ISP 1 and ISP 2.
This occurrence suggests that the network problem is happening on a network segment that is common to both ISPs, potentially occurring in the LAN or directly on the SD-WAN Edge Router.
The cause of this issue is likely high CPU usage, resulting in high packet loss. This is a common problem that arises when the device does not have enough available resources to manage the throughput.
Using the historical data available on the dashboard, you can analyze the network performance to identify triggers, patterns, or deviations from the baseline. This analysis can help you determine when the problem first occurred, whether it is continuous or intermittent, and whether it is flapping.
By examining the screenshot above, you can see a pattern indicating an intermittent network problem that occurs intermittently and does not follow a specific pattern.
However, the high CPU usage is evident and requires attention.
With SD-WAN monitoring, you have the power to uncover the root cause of any network issues.
In addition to monitoring and analyzing network performance, you can use Obkio Vision, a free visual Traceroute tool that continually runs to identify any problems in your WAN and over the Internet.
This tool is invaluable in pinpointing the exact location and cause of any issues affecting your network.
