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.

TotalView offers network monitoring as well as root-cause troubleshooting of problems in plain-English. The solution monitors every device as well as every interface on every device. In addition, TotalView goes deep, collecting 19 error counters, performance, configuration, and connectedness so nothing is outside of it’s view. A built-in heuristics engine analyzes this information to produce plain-English answers to problems. Complex problems can now be solved by junior level engineers leaving the senior level engineers to work on more strategic level projects. The core product includes everything needed to run a perfectly healthy network: Configuration management, server monitoring, cloud service monitoring, IPAM, NetFlow, path mapping, and diagramming. Get Total Network Visibility on your network and solve more problems faster.

VisualEther
VisualEther transforms Wireshark's packet captures (PCAP/PCAPNG) into easily interpretable sequence diagrams, allowing AI coding agents such as Claude Code to articulate, in straightforward language, the reasons behind a network session's failure. While Wireshark provides a detailed view of each packet, it does not present the overall conversation; VisualEther generates this conversation directly from the capture file—ensuring accuracy and reproducibility—with over 82 integrated protocol templates that cover a wide range, including 5G NR, 5G core, LTE, IMS/VoLTE, SIP/RTP, BGP, OSPF, DNS, HTTP/2, HTTP/3, TLS, Kerberos, Diameter, GTP, and various industrial protocols like Modbus, DNP3, and EtherNet/IP. An included MCP server selectively extracts only the relevant messages and fields, enabling an AI agent to process kilobytes of structured information rather than an overwhelming amount of raw packet data, effectively conducting an author-debug-verify cycle that references specific frame numbers as proof. Built upon the functionality of tshark, if Wireshark can analyze it, VisualEther can create a diagram for it. With capabilities for observation, analysis, diagnosis, and automation, VisualEther is available on Windows (through winget), macOS (via Homebrew), and Linux (using apt/dnf), offering a free Community edition alongside paid Professional and Server editions for more advanced needs. This comprehensive tool not only streamlines network analysis but also enhances the troubleshooting process for IT professionals.
