Availability

• CSV export reports

  With the Export as CSV capability, you can download the path graph points (virtual/member path) for any time series (hourly, weekly, and so on) as an excel Comma-separated Value (CSV) file and be able to plot all distinct points of data for a particular site report.

  To download/export the path graph as CSV, navigate to Reports > Quality at site level. Select the site and metric from the drop-down list and click the Export as CSV link.

  Select the path that you want to fetch the data for and click Download Graph Points.

  

  By default, all the path check boxes are auto selected. You can modify it as needed.

  Note

  If paths are selected, the Download Graph Points button remains disabled.

  

  Currently, the naming convention of the downloaded CSV file is SiteQuality followed by the download. You can view each path with a pair of time and value along with a unique identifier. You can see the time in milliseconds and the value as in unit.

  

  Based on the following metric selection, you can see that different values are getting generated in the excel sheet:

  • Loss: Value shows in %.
  • Latency and Jitter: Value shows in milliseconds.
  • Throughput: Value shows in Kbps.

  • Availability: Shows the path up, partially up, down, and unknown time.

    • If the value is 4, then the path is in Up state.

Quality of Service

Quality of Service (QoS) manages data traffic to reduce packet loss, latency, and jitter on the network. For more information, see Quality of Service. The following are two ways to view the Quality-of-Service (QoS) report:

• Summary View: Summary view provides an overview of bandwidth consumption across all types of traffic - real-time, interactive, bulk, and control across the network and per site.

  

  • Real-time: Used for low latency, low bandwidth, time-sensitive traffic. Real-time applications are time sensitive but don’t really need high bandwidth (for example voice over IP). Real-time applications are sensitive to latency and jitter, but can tolerate some loss.

  • Interactive: Used for interactive traffic with low to medium latency requirements and low to medium bandwidth requirements. Interactive applications involve human input in the form of mouse clicks or cursor moves. The interaction is typically between a client and a server. The communication might not need high bandwidth but is sensitive to loss and latency. However, server to client does need high bandwidth to transfer graphical information, which might not be sensitive to loss.

  • Bulk: Used for high bandwidth traffic that can tolerate high latency. Applications that handle file transfer and need high bandwidth are categorized as bulk class. These applications involve little human interference and are mostly handled by the systems themselves.

  • Control: Used to transfer control packets that contain routing, scheduling, and link statistics information.

• Detailed View: The detailed view captures trends around bandwidth consumption, traffic volume, packets dropped and so on For each QoS class associated with an overlay virtual path. You can view QoS statistics based on the virtual path between two sites.

  

Historical statistics

For each site, you can view the statistics as graphs for the following network parameters:

• Virtual Paths

Services

To view the Services statistics, navigate to Reports > Statistics > Services tab.

Select the service type from the list. The options are as follows:

• Passthrough – This service manages traffic that is not intercepted, delayed, shaped, or changed by the SD-WAN. Traffic directed to the Passthrough Service includes broadcasts, ARPs, and other non-IPv4 traffic, and traffic on the Virtual WAN Appliance local subnet, configured subnets, or Rules applied by the Network Administrator. This traffic is not delayed, shaped, or changed by the SD-WAN. Therefore, you must ensure that Passthrough traffic does not consume substantial resources on the WAN links that the SD-WAN Appliance is configured to use for other services.

• Intranet – This service manages Enterprise Intranet traffic that has not been defined for transmission across a Virtual Path. As with Internet traffic, it remains unencapsulated, and the SD-WAN manages bandwidth by rate-limiting this traffic relative to other service types during times of congestion. Under certain conditions, and if configured for Intranet Fallback on the Virtual Path, traffic that ordinarily travels with a Virtual Path can instead be treated as Intranet traffic, to maintain network reliability.

• Internet – This service manages traffic between an Enterprise site and sites on the public Internet. Traffic of this type is not encapsulated. During times of congestion, the SD-WAN actively manages bandwidth by rate-limiting Internet traffic relative to the Virtual Path, and Intranet traffic according to the SD-WAN configuration established by the Administrator.

You can view the following metrics:

• Site Name: The site name.
• Bandwidth Upload: Upload (LAN > WAN) Bandwidth usage for the selected time period.
• Packets Upload: Upload (LAN > WAN) Packets sent for the selected time interval.
• Packets Dropped Upload: Number of upload packets dropped.
• Drop Percentage Upload: Percentage of upload data dropped.
• Expand/Collapse: You can expand or collapse the data as needed.

GRE tunnels

You can use a tunneling mechanism to transport packets of one protocol within another protocol. The protocol that carries the other protocol is called the transport protocol, and the carried protocol is called the passenger protocol. Generic Routing Encapsulation (GRE) is a tunneling mechanism that uses IP as the transport protocol and can carry many different passenger protocols.

The tunnel source address and destination address are used to identify the two endpoints of the virtual point-to-point links in the tunnel. For more information about configuring GRE tunnels on Citrix SD-WAN appliances, see GRE Tunnel.

To view GRE Tunnel statistics, navigate to Reports > Statistics > GRE Tunnels tab.

You can view the following metrics:

• Site Name: The site name.
• Tx Bandwidth: Bandwidth transmitted.
• Rx Bandwidth: Bandwidth received.
• Packet Dropped: Number of packets dropped, because of network congestion.
• Packets Fragmented: Number of packets fragmented. Packets are fragmented to create smaller packets that can pass through a link with an MTU that is smaller than the original datagram. The fragments are reassembled by the receiving host.
• Expand/Collapse: You can expand or collapse the data as needed.

IPsec tunnels

IP Security (IPsec) protocols provide security services such as encrypting sensitive data, authentication, protection against replay, and data confidentiality for IP packets. Encapsulating Security Payload (ESP), and Authentication Header (AH) are the two IPsec security protocols used to provide these security services.

In IPsec tunnel mode, the entire original IP packet is protected by IPsec. The original IP packet is wrapped and encrypted, and a new IP header is added before transmitting the packet through the VPN tunnel. For more information about configuring IPsec tunnels on Citrix SD-WAN appliances, see IPsec Tunnel Termination.

To view IPsec Tunnel statistics, navigate to Reporting > statistics > IPsec Tunnels tab.

O365 Metrics

Citrix SD-WAN allows you to not only perform beacon probing, but also determines the latency to reach Office 365 endpoints through each WAN link. The latency is the round trip time taken to send a request and get a response from the Office 365 beacon service over a WAN link. This enables network administrators to view the beacon service latency report and manually choose the best internet link for direct Office 365 breakout. Beacon probing is enabled only through the Citrix SD-WAN Orchestrator service. By default, beacon probing is enabled on all Internet enabled WAN links when Office 365 break-out is enabled through the Citrix SD-WAN Orchestrator service.
