Question

An ecommerce company is experiencing latency issues with online shops during Black Friday's peak season. The BIG-IP Administrator detects an overall high CPU load on the BIG-IP device and wants to move the top utilized Virtual Servers to a dedicated BIG-IP device. Where should the BIG-IP Administrator determine the problematic Virtual Servers?

Options

  • ASystem > Plattform
  • BLocal Traffic > Virtual Servers > Virtual Server List
  • CLocal Traffic > Network Map
  • DStatistics > Module Statistics > Local Traffic > Virtual Servers

Why each option

To identify which Virtual Servers are contributing most to high CPU load on a BIG-IP device, the administrator should consult the detailed statistics available under Statistics > Module Statistics > Local Traffic > Virtual Servers. This section provides granular performance metrics for each virtual server.

ASystem > Plattform

'System > Platform' typically provides hardware and system-level information, not granular traffic statistics per virtual server.

BLocal Traffic > Virtual Servers > Virtual Server List

'Local Traffic > Virtual Servers > Virtual Server List' displays a list of configured virtual servers and their basic status, but it does not provide detailed real-time performance statistics needed to identify high utilization.

CLocal Traffic > Network Map

'Local Traffic > Network Map' offers a visual representation of the traffic flow, including virtual servers, pools, and nodes, but it is not the primary location for detailed statistical analysis of resource consumption.

DStatistics > Module Statistics > Local Traffic > Virtual ServersCorrect

The path 'Statistics > Module Statistics > Local Traffic > Virtual Servers' in the BIG-IP Configuration Utility provides detailed statistical information for each virtual server, including connection rates, throughput, and CPU utilization. This data is essential for identifying which specific virtual servers are most heavily utilized and contributing to the overall high CPU load.
