How to Monitor Cisco SD-WAN with CA Network Monitoring Tools



If you were wondering if software defined networking (SDN) was really a driving force yet in the industry – Cisco recently announced that they are ready to upgrade a million routers with their SD-WAN software.

SD-WAN introduces software-defined intelligence to regulate the enterprise WAN for optimal application experiences. Yet, the enterprise needs to monitor and validate this intelligence along with their traditional network for full assurance without adding any more complexity to their day-to-day monitoring activities then there already is.

With the recent Cisco announcement, it is more imperative today then every before that network teams adopt a comprehensive and unified approach to monitoring traditional WAN and SD-WAN environments. CA’s Network Operations and Analytics solution is a unified, full-stack monitoring and analytics platform for assuring traditional and software-defined networks and provides:

  1. SDN relationship mapping that enables easy VNF management
  2. Validation of traffic decisions made by SD-WAN intelligence
  3. Easy troubleshooting workflows to assure SD-WAN health
  4. Unified monitoring of SD-WAN and traditional WAN

So how do you start monitoring your Cisco SD-WAN environment with CA? We break it down for you here:

To discover your Cisco SD-WAN environment, configure the SDN monitoring plugin to monitor inventory and performance across your vEdge routers, interfaces, tunnels, application and SLA paths. Once configured and discovered, CA’s network monitoring tools reveal performance metrics on a variety of instances including CPU, memory and disk utilization, NetFlow statistics, jitter, latency and packet loss and many others.

“PROTOCOL”: “https”,
“INVENTORY_POLL_RATE”: “0 */10 *”,

Cisco SD-WAN Tunnel and Application Paths Dashboards

Utilize the SD-WAN Tunnel Statistics dashboard or the SD-WAN App Path Statistics dashboard to view the health of your SD-WAN tunnels or application/SLA paths. The SD-WAN App Path Statistics dashboard lets you easily identify issues impacting your delivering of services and applications according to service level agreements (SLAs).

The SD-WAN Tunnel Statistics dashboard reports the following metrics:

  1. Jitter
  2. Latency
  3. Packet loss

The SD-WAN App Path Statistics dashboard reports the following metrics:

  1. Percentage of Jitter SLA Threshold
  2. Percentage of Packet Loss SLA Threshold
  3. Percentage of Latency SLA Threshold

The following details appear in these dashboards:

Cisco SD-WAN Health Counts
View the aggregated health counts of the following items:

  1. Sites
  2. Edge Routers
  3. Application Paths
  4. Applications
  5. Tunnels

Counts appear in color-coded circles for each threshold range. To expand the view, click the arrow in the lower-right corner. Click a card title or a circle to view the corresponding details in the expanded view.

Cisco SD-WAN Geographic Maps

View the location of each site. When a site is selected, the connections to and from other sites appear. The connection lines are color-coded based on health metrics. Site router details appear when you hover over a site. Tunnel or application/SLA path details appear when you hover over a connection.

Cisco SD-WAN Timelines

View time bar charts aggregating packet loss, latency, and jitter metrics and time bar charts for each metric. The selected site in the Map view filters this view.

Cisco SD-WAN Scorecards

View tunnel or application/SLA path metrics by subgroup and component for the selected group. Subgroups and the items in those groups appear in a hierarchical format. Colored icons indicate performance levels for metrics and an overall health indicator.

With the ability to have deep visibility and context of network issues—across all application service chains, individual network nodes and endpoints—network operations teams now have the ability to significantly reduce time to resolution while enhancing user experience satisfaction across traditional and software defined network architectures.
