NetIQ Qcheck
NetIQ Qcheck is a network diagnostic and performance measurement tool developed by NetIQ. It allows administrators and network engineers to test network connectivity, latency, throughput, and packet loss between hosts, assisting in troubleshooting network issues and validating network configurations. It facilitates proactive monitoring to ensure optimal network performance..
NetIQ Qcheck utilizes Port 10114 to facilitate communication between the Qcheck console and the remote agents installed on network devices or endpoints. This enables detailed performance assessments, including round-trip latency, available bandwidth, streaming capabilities, and packet loss. The tool supports both TCP and UDP protocols to provide versatile connections depending on the nature of tests required.
Administrators use Qcheck either standalone or integrated within NetIQ's suite of network management utilities to verify application delivery paths, test firewall configurations, and benchmark adjustments to infrastructure or routing. The use of both protocols helps simulate real-world traffic businesses typically handle, making diagnostics more relevant.
By sending test packets and analyzing their successful delivery, Qcheck builds a detailed picture of network health. Its ability to perform variable tests enables fine-grained insight into specific issues such as congestion points, intermittent connectivity failures, or bandwidth bottlenecks.
