NetCrunch is commercial, self-hosted, agentless network and IT infrastructure monitoring software for Windows Server. It monitors network devices, servers, virtualization platforms, cloud services, applications, websites, logs, telemetry, and network traffic across distributed environments.
NetCrunch supports 680+ monitoring targets and provides 270+ ready-to-use Monitoring Packs for devices, applications, and operating systems. Policy-based monitoring automatically applies monitoring settings, Monitoring Packs, thresholds, and alerts to matching devices and systems. Licensing is based on monitored nodes and network interfaces rather than individual sensors, checks, or metrics.
NetCrunch provides real-time dashboards and automatic Layer 2 and routing topology maps for visibility into network status and performance. Network traffic analysis supports NetFlow, sFlow, IPFIX, and other flow technologies. Its alerting system supports event correlation, dependency-aware suppression, predictive thresholds, escalation, and 40+ automated response actions, including scripts, notifications, API calls, and integrations with external systems.
Distributed Monitoring Probes extend monitoring to remote and isolated locations. NetCrunch also provides a REST API for integration and automation with external IT management, service management, and operational systems.
NetCrunch is self-hosted on Windows Server and can monitor on-premises, air-gapped, cloud, and hybrid IT environments.

TRex
TRex is a cost-effective, open-source traffic generator that can operate in both stateful and stateless modes, leveraging DPDK for efficient performance. Capable of producing L3-7 traffic, it consolidates the functions of multiple commercial tools into a single solution. The stateless features allow for the management of various streams, modifications to packet fields, and provide detailed statistics, including latency and jitter for each stream or group. Its advanced stateful capabilities enable the emulation of Layer 7 traffic, offering comprehensive support for TCP and UDP protocols. Furthermore, TRex is equipped to simulate a diverse array of client-side protocols such as ARP, IPv6, ND, MLD, IGMP, ICMP, DOT1X, DHCPv4, DHCPv6, and DNS, thereby creating a realistic environment for testing the scalability of clients and servers. With its robust functionality, TRex stands out as a versatile tool for network testing and performance evaluation.

Nping
Nping is a free software utility designed for generating network packets, analyzing responses, and measuring response times. It supports a diverse array of protocols, giving users comprehensive control over the headers of each packet. Although Nping can function as a basic ping tool to identify active devices on a network, it also serves as a raw packet generator that can be employed for stress testing network stacks, executing ARP spoofing, launching Denial of Service attacks, and performing route tracing, among other uses. Additionally, Nping features an innovative echo mode that allows users to observe alterations in packets as they travel from the source to the destination. This capability proves beneficial for understanding firewall configurations, identifying packet corruption issues, and gaining deeper insights into network performance.
