One feature I liked is end-user monitoring.
ThousandEyes provides excellent service and support in maintaining connection quality and offers deep network monitoring capabilities with a path analyzer for troubleshooting. It delivers full monitoring between applications and end-users and is scalable for network administrators. Despite its cost, integration difficulties with certain Cisco products, absence of application-level monitoring, and needs for improved network reporting and documentation, ThousandEyes remains an effective tool with many benefits for tech buyers.
