Checking System Health
The Health Check pages in SCM let you check the status of the hardware, software, and network status in your SteelConnect system per organization. These pages give you both summary and detailed information about key system components to answer questions such as:
•How many tunnels are actively communicating with other tunnels in an overlay network? Are any tunnels degraded and no longer communicating?
•Are the uplinks and WANs for an organization functioning properly? Is QoS enabled in the WAN?
•Do I need to adjust the default appliance thresholds to meet the Service Level Agreements?
•How many subnets and zones are used in each site?
•Are all of the appliances in the corporate headquarters running the same firmware version?
Getting a summary of system health
To display the overall system health per organization, choose Health Check.
Access additional Health Check pages from the Summary window or from the left navigation pane. These pages are organized into top-down, hierarchical layers. The Overlay Health page provides a high-level SD-WAN overview. More detailed networking information is provided in the Uplink Health and Zone Health pages. The lowest layer, Appliance Health, gives the physical or virtual appliance status.
Status icons give you a quick visual representation of the health of each layer. For more details, choose a particular category or click the icon next to that category. For example, choose Zone Health or click the status icon to the left of Subnets to open the Zone Health page.
Expanding the Health Check page
Events in the lower layers can affect the status at higher layers; for example, a change in uplink status can change the overlay status.
Windows in a page include nested, collapsible tables. For example, the Subnet window displays a table that shows subnets at an organization level. Click > or a status icon for more details.
Expanding the Subnet window
A top-level summary shows the lowest status of any of the components in the table. For example, if a site’s subnets are being shown at the top level, and a single zone in the site has a status of Faulty, the status for the entire site is shown as Faulty.
The health conditions are arranged into these categories:
•Overlays - Provides an overview of the overlay networks used in the organization. See Checking network overlays for more information about the Overlay page, including icon definitions.
–Tunnels up - The number of tunnels that are showing a health condition of Ready; that is, active and communicating with the other tunnels in the network.
–Tunnels degraded - The number of tunnels that are showing a health condition of Degraded.
–Tunnels down - The number of tunnels that are showing a health condition of Faulty.
–Tunnels ignored - This field is reserved for future use.
•Uplinks - Provides uplink and WAN status and QoS and routing parameters for each organization. See Checking uplinks for more information about the Uplink page, including icon definitions.
–Uplinks up - The number of uplinks that are active (showing a health condition of Ready).
–Uplinks degraded - The number of uplinks that are showing a health condition of Degraded.
–Uplinks down - The number of uplinks that are showing a health condition of Faulty.
–Uplinks ignored - This field is reserved for future use.
•Subnets - Provides a summary status of the subnets used on the LAN side of the network topology. This list includes both static subnets and dynamic subnets that are defined by routing protocols such as OSPF or BGP.
See Checking zones and subnets for more information about the Subnet page, including icon definitions.
–Subnets up - The number of subnets that are working (showing a health condition of Ready).
–Subnets degraded - The number of subnets that are showing a health condition of Degraded.
–Subnets down - The number of subnets that are showing a health condition of Faulty.

–Appliances up - The number of appliances that are active, functional, and able to communicate with the rest of the appliances in the overlay network (showing a health condition of Ready).
–Appliances degraded - There is a connectivity, configuration, firmware, or CPU issue with one or more appliances (showing a health condition of Degraded).
–Appliances down - The number of appliances that are showing a health condition of Faulty.
–Appliances ignored - This field is reserved for future use.
Checking network overlays
The Overlay Health page shows the overlay network’s health per organization and site. Overlay networks are the automatically configured VPN (AutoVPN) tunnels that are created between sites that use SteelConnect gateways.
The initial view (Global topology) shows all sites in the organization. To view information for a site, select a site from the Site drop-down list, or click the right arrow to the left of the table.
The Global topology level shows the lowest health rating for any site in the topology. For example, if nine sites’ tunnels are healthy but one site’s tunnel is degraded, the Global topology shows a status of Degraded in the Tunnels column of the table.
This page shows twice the number of tunnels that you see on the dashboard map and in the Health Check Summary window. The dashboard map provides a graphic view of a single full-duplex tunnel, and the Health Check Summary counts tunnels between sites as a single tunnel. However, the Overlay Health page counts tunnels between sites as two tunnels—one tunnel from the local site to the remote site, and one tunnel from the remote site to the local site.

Faulty - One or more tunnels are operating at a Poor level.
This value is based on overall path quality (Excellent, Good, Fair, or Poor), which is taken from the threshold values used by the appliances to apply path selection.
The PQ information takes latency, jitter, and packet loss into consideration. QoS for gateways uses the common applications kept enhanced (CAKE) scheduler, and these values are not configurable. For more details about CAKE, see How does QoS for gateways work?.
SCM calculates an average of each tunnel’s PQ data in each WAN connected to the site to provide an overall rating for all WANs.
To find path quality data, click the tunnel on the dashboard or choose Visibility, choose WAN paths, and click the Status indicator.
