Create a SaaS Quality Profile

Configure a Software-as-a-Service (SaaS) quality profile to specify a SaaS application for a hub firewall with a Direct Internet Access (DIA) link.

If your branch firewall has a Direct Internet Access (DIA) link to a Software-as-a-Service (SaaS) application, create a SaaS Quality profile to specify how one or more SaaS applications should be monitored. SaaS Quality profiles are associated with an SD-WAN policy rule to determine how the branch firewall determines the path quality thresholds for latency, jitter, and packet loss and selects the preferred path for an outgoing packet.

The SaaS Quality profile supports up to four static IP addresses, or one fully qualified domain name (FQDN) or URL per SaaS Quality profile. When multiple static IP addresses are configured, the branch firewall monitors one IP address at a time in a cascading order based on how the IP addresses are ordered in the SaaS Quality profile. For example, if you add IP1, IP2, IP3, and IP4, the branch firewall monitors IP1 to determine if the path quality thresholds have been exceeded, then continues to IP2, and so forth.

SD-WAN monitoring and reporting data displays the SaaS application and SaaS application IP, FQDN, or URL as it is currently configured in the SaaS Quality profile associated with an SD-WAN policy rule regardless of the time filter applied when viewing your SD-WAN monitoring data.

For example, three days ago you initially configured the IP address of your SaaS application as 192.168.10.50 in a SaaS Quality profile and had traffic match the SD-WAN policy rule to which the SaaS Quality profile is associated. Today, you reconfigured this existing SaaS Quality profile and changed the SaaS application IP address to 192.168.10.20. When you go review the SD-WAN monitoring data, all existing monitoring data for this SaaS application display the IP address 192.168.10.20.

Log in to the Panorama web interface.
Select ObjectsSD-WAN Link ManagementSaaS Quality Profile and specify the Device Group containing your SD-WAN configuration.
Add a new SaaS quality profile.
Enter a descriptive Name for the SaaS Quality profile.
(Optional) Enable (check) Shared to make the SaaS Quality profile shared across all device groups.
(Optional) Enable (check) Disable override to disable overriding the SaaS Quality profile configuration on the local firewall.

Disable override can only be enabled if Shared is disabled in the previous step.
Configure the SaaS Monitoring Mode.
- Automatically monitor the SaaS application path health.
  Enabled by default, Adaptive monitoring allows the branch firewall to passively monitor the SaaS application session for send and receive activity to determine if the path quality thresholds have been exceeded. The SaaS application path health quality is automatically determined without any additional health checks on the SD-WAN interface.
  
  Adaptive SaaS monitoring is supported only for TCP SaaS applications.
- Configure the Static IP address for the SaaS application.
  
  Create a SaaS Quality profile per critical SaaS application that you need monitored. If a SaaS application has multiple IP addresses, configure a SaaS Quality profile with the multiple static IP addresses for that SaaS application.
  SaaS monitoring is resource-intensive and may impact firewall performance if monitoring a large number of SaaS applications. It is a best practice to only monitor those business-critical SaaS applications that need good usability.
  1. Select IP Address/ObjectStatic IP Address and Add an IP address.
  2. Enter the IP address of the SaaS application or select a configured address object.
  3. Enter the Probe Interval by which the branch firewall probes the SaaS application path for health information.
  4. Click OK to save your configuration changes.
- Configure the fully qualified domain name (FQDN) for the SaaS application.
  1. Configure a FQDN address object for the SaaS application.
  2. Select IP Address/ObjectFQDN and Add the FQDN.
  3. Select the FQDN address object for the SaaS application.
  4. Enter the Probe Interval by which the branch firewall probes the SaaS application path for health information.
  5. Click OK to save your configuration changes.
- Configure the URL for the SaaS application.
  
  URL monitoring is only supported for traffic over ports 80, 443, 8080, 8081, and 143.
  1. Select HTTP/HTTPS.
  2. Enter the Monitored URL of the SaaS application.
  3. Enter the Probe Interval by which the branch firewall probes the SaaS application path for health information.
    The minimum probe interval supported for a SaaS application HTTP/HTTPS is 3 seconds.
  4. Click OK to save your configuration changes.
