Native SD-WAN monitoring tools are not enough, survey says

SD-WAN platforms provide some native monitoring, but supplemental monitoring tools are needed, particularly when seeking the root cause of poor application performance, according to an Enterprise Management Associates survey.

(Editor’s note: A recent Enterprise Management Associates survey of 303 WAN managers found that native monitoring is an important factor in choosing SD-WAN products, but many respondents say additional third-party monitoring tools are also needed. This article by EMA Vice President of Research Networking Shamus McGillicuddy explores some of the survey results  included in the report “Enterprise WAN Transformation: SD-WAN, SASE, and the Pandemic” that is based on the survey.)

SD-WAN technology offers native monitoring capabilities that can enhance network operations. It’s a major selling point, right up there with hybrid WAN connectivity and direct cloud connectivity, but native SD-WAN monitoring is not a replacement for traditional network monitoring tools.

SD-WAN products typically have a cloud-based controller that offers both visiblity and management for the overlay that SD-WAN creates on a company’s physical WAN. Most of the SD-WAN-controller consoles offer reports and dashboards with clear insights into performance by site, by application, and by cloud provider.

This visiblity component is essential to an SD-WAN implementation, and the survey found that enterprises list native monitoring as the third most important SD-WAN product requirement. (The first two are hybrid-connectivity support and integrated network security.) Also, 48% of IT organizations consider improved visiblity a top driver of SD-WAN adoption.
