Monitoring SD-WAN links from the firewall’s administration interface

The monitoring module makes it possible to show the status of SD-WAN gateways as well as the values of the metrics relating to SLA thresholds.

Overview: dashboard of health indicators

The SD-WAN dashboard, available in the Monitoring tab > Dashboard module > Health indicators section, offers a quick view of the status of all SD-WAN objects:

The color of the SD-WAN icon varies according to the status of the routers and gateways used in the firewall configuration:

  • Green: all router gateways are functional and meet the defined SD-WAN SLA criteria,
  • Orange: a router has a degraded status as one of its gateways has a degraded status, or cannot be reached,
  • Rouge: a router cannot be reached as all its gateways are unreachable.

Clicking on this icon will take you directly back to Monitoring > SD-WAN.

Detailed view: the SD-WAN monitoring module

The SD-WAN module, which can be accessed from Monitoring > Monitoring, shows details of routers and gateways used in the firewall's routing settings (default route, static routes and policy-based routing).

Real time tab

The Real time tab shows information about the status of monitored routers and gateways, as well as the SD-WAN SLA values of these gateways.

The values may be as follows:

Type Status SLA status
Gateway
  • Enabled,
  • Standby (redundant),
  • Unreachable.
  • Good,
  • Degraded,
  • Unreachable.
Router
  • Functional (load balancing),
  • Functional (redundant - at least one gateway is on standby),
  • Degraded,
  • Unreachable.
  • Good,
  • Degraded,
  • Unreachable.

Example of a router with load balancing

For more details on the values that the various indicators may show, refer to the module on SD-WAN monitoring in the Stormshield SNS v4 user guide.

In this example, both gateways have been enabled.

Load balancing values between both gateways are shown: they depend on the weight assigned to each gateway. When all gateways have a weight of 1, this means that each of them have been assigned 100% load balancing:

By scrolling over the SLA status of a gateway, the last measured indicator value will be shown:

Example of a router with failover

One gateway is active, while the other is on standby.

Load balancing between both gateways is indicated: the active gateway indicates 100%, while the standby gateway is at 0%.

By scrolling over the SLA status of a gateway, the last measured indicator value will be shown:

Real time chart tab

In this tab, a router gateway can be selected to display curves that show changes to the following SLA indicators over the past 10 minutes:

  • Latency,
  • Percentage of time spent in the various possible statuses (functional, degraded and unreachable).

Example:

History tab

In this tab, up to five router gateways can be selected to display curves that show changes to the various SLA indicators over the selected period:

  • Jitter and latency,
  • Packet loss rate and unavailability rate,
  • Percentage of time spent in the various possible statuses (functional, degraded and unreachable).
