  • Strata Cloud Manager
  • Prisma SD-WAN license

Start with the Zscaler Test Page to verify and troubleshoot client traffic to and through Zscaler Enforcement Nodes (ZENs). All application and path metrics will also be collected and reported, and all application monitoring alarms and alerts will be generated for Standard VPNs. To troubleshoot Standard VPNs, view Alerts and Alarms, Connectivity of Standard VPNs at the site level, and Activity charts to view possible issues with the VPN. In addition, device toolkit commands can be used to view Standard VPN stats, status, and summary.

Use the Zscaler Test Page

Zscaler provides a diagnostic page that allows for verification and troubleshooting of client traffic to and through Zscaler ZENs. To access the page from any client, open the link http://ip.zscaler.com.
For more details on this tool, refer to the Zscaler Knowledgebase article, How can I check if a user’s traffic is going to Zscaler?.
