diagnose server-load-balance vs_stat
Use this command to display statistics and health information for virtual servers and real server pool members. The command reports availability status, session distribution, throughput, response times, and the timestamp of the last state change (UP or DOWN).
This information is useful for monitoring load-balancing behavior, verifying server availability, and troubleshooting performance issues directly from the CLI without relying on the GUI.
Syntax
