VPN Monitoring and Troubleshooting in Security Cloud Control

Monitor Site-to-Site VPNs using Site-to-Site VPN Summary Page

You can view a summary of your site-to-site VPN topologies in the Site-to-Site VPN Summary page. For each topology, you can view details such as VPN type, network topology, VPN interfaces, VPN devices, and tunnel statuses.

You can edit or delete the topology using the edit and delete buttons. For SASE topology VPNs, you have options to deploy, edit and delete any topology.

Monitor Remote Access VPN Sessions

The Security Cloud Control Remote Access Monitoring dashboard can be used to view consolidated information about RA VPN users, including the current status of users, device types, client applications, user geolocation information, and duration of connections. You can also disconnect RA VPN sessions as needed.

See Monitor Remote Access Virtual Private Network Sessions for more information.

SD-WAN Summary Dashboard

The SD-WAN Summary dashboard (Overview > Dashboards > SD-WAN SummaryAnalysis > SD-WAN Summary) provides a snapshot of your WAN devices and their interfaces. This dashboard helps you to:

  • Identify issues with the underlay and overlay (VPN) topologies.

  • Troubleshoot VPN issues using the existing Health Monitoring, Device Management, and Site-to-Site Monitoring pages.

  • Monitor application performance metrics of WAN interfaces. The threat defense steers application traffic based on these metrics.

A WAN device must meet one of the following criteria:

  • The device must be a VPN peer.

  • The device must have WAN interface.

A WAN interface must meet one of the following criteria:

  • The interface has IP address-based path monitoring enabled on it.

  • The interface has a Policy Based Routing (PBR) policy with at least one application configured to monitor it.

For more information about PBR policy and path monitoring, see Policy Based Routing.

Click Uplink Decisions to view the VPN Troubleshooting page. You can view syslogs with ID: 880001. These syslogs show the threat defense interfaces through which it steers traffic based on the configured PBR policy.

To view the above syslogs and to view the data on this dashboard, ensure that you review Prerequisites for Using SD-WAN Summary Dashboard.

For clusters, this dashboard displays application performance metrics of only the control node and not the data nodes.

Prerequisites for Using SD-WAN Summary Dashboard

  • You must be an Admin, Security Analyst, or Maintenance user to view this dashboard. See Secure Firewall Management Center and Cloud-delivered Firewall Management Center User Role Mapping for more information.

  • Threat defense devices must be Version 7.2 or later.

  • Enable IP-based path monitoring and HTTP-based application monitoring on the WAN interfaces.

    1. Choose Devices > Device Management.

    2. Click the edit icon adjacent to the device that you want to edit.

    3. Click the edit icon adjacent to the interface that you want to edit.

    4. Click the Path Monitoring tab.

    5. Check the Enable IP based Monitoring check box.

    6. Check the Enable HTTP based Application Monitoring check box.

    7. Click OK.

  • Configure a PBR policy with at least one application configured to monitor it:

    1. Choose Devices > Device Management.

    2. Click the edit icon adjacent to the device that you want to edit.

    3. Click Routing.

    4. In the left pane, click Policy Based Routing.

    5. Click Add.

    6. From the Ingress Interface drop-down list, choose an interface.

    7. Click Add to configure a forwarding action.

    8. Configure the parameters.

    9. Click Save.

  • To view syslogs when you click Uplink Decisions, you must:

    • Choose Devices > Platform Settings and create or edit a threat defense policy.

    • In the left pane, click Syslog.

    • Click the Logging Setup tab.

    • Check the Enable Logging check box to turn on the data plane system logging for the threat defense device.

    • Click the All Logs radio button to enable logging of all the troubleshooting syslog messages.

      or

      Click the VPN Logs radio button to enable logging of only the VPN troubleshooting messages.

    • Click Save.

Monitor WAN Devices and Interfaces Using the SD-WAN Summary Dashboard

The SD-WAN Summary dashboard has the following widgets :

WAN Connectivity

This widget provides a summary of the WAN interfaces statuses. It shows the number of WAN interfaces that are in the Online, Offline or No Data states. Note that you cannot monitor subinterfaces using this widget.

Click View All Interfaces to view more details about the interfaces in the health monitor page.

If a WAN interface is in the Offline or No Data state, you can troubleshoot it from the health monitor page:

  1. In the Monitoring pane, expand Devices.

  2. Click the corresponding WAN device to view the device-specific health details.

  3. Click the Interface tab to view the interface status and aggregate traffic statistics for a specific time.

    Alternatively, you can click View System & Troubleshoot Details. The health monitor page is displayed with all the necessary details.

VPN Topology

This widget provides a summary of the site-to-site VPN tunnel statuses. It shows the number of Active, Inactive, and No Active Data VPN tunnels.

Click View All Connections to view the VPN tunnel details in the Site-to-site VPN Monitoring dashboard.

If the tunnels are in the Inactive or No Active Data state, you can troubleshoot using the Site-to-site VPN Monitoring dashboard. In the Tunnel Status widget, hover your cursor over a topology, click View (View button) and do one of the following:

  • Click the CLI Details tab to view the details of the VPN tunnels.

  • Click the Packet Tracer tab to use the packet tracer tool for the topology.

Interface Throughput

This widget monitors the average throughput of the WAN interfaces during the chosen time period.

The interface throughput is classified into four bands. These details aid in cost planning and resourcing. You can choose a time range for the widget data from the Show Last drop-down list. The range is from 15 minutes to two weeks.

Click View Health Monitoring to view more details about the interface in the health monitor page.

Device Inventory

This widget lists all the managed WAN devices and groups them according to the model.

Click View Device Management to view more details about the device in the Device Management page.

WAN Device Health

This widget displays the device count according to the health of the WAN devices. You can view the number of devices with errors, warnings, or those that are in Disabled state.

Click View Health Monitoring to view the alarms, and quickly identify, isolate, and resolve issues.

If the health of a device is affected, you can troubleshoot it from the health monitor page.

  1. In the Monitoring pane, expand Devices.

  2. Click the corresponding WAN device to view the device-specific health details.

  3. Click View System & Troubleshoot Details. The health monitor page is displayed with all the necessary details.

A device can be in Disabled state for multiple reasons, including the following:

  • Management interface is disabled.

  • Device is powered off.

  • Device is being upgraded.

Monitor Application Performance Metrics of WAN Interfaces Using the SD-WAN Summary Dashboard

Under the Application Monitoring tab, you can select a WAN device and view the application performance metrics for the corresponding WAN interfaces. These metrics include Jitter, Round Trip Time (RTT), Mean Opinion Score (MOS), and Packet Loss.

By default, the metrics data is refreshed every 5 minutes. You can change the refresh time; the range is from 5 to 30 minutes. You can view the metrics in tabular and graphical formats. For each WAN interface, the latest metric value appears in the table. For graphical data, you can choose a time interval of up to 24 hours to view the metrics data for the corresponding WAN interfaces.
