TCP Monitor Plus

TCP Monitor Plus is a lightweight, portable, and completely free network diagnostic and troubleshooting tool specifically designed for Windows operating systems. Developed by OGA, it serves as an all-in-one utility that aggregates bandwidth monitoring features with core IP diagnostic tools.

Because it is a portable application, it does not require installation; you can run its executable file directly from a desktop or a USB drive on any system. 📊 Real-Time Bandwidth & Traffic Monitoring

The primary screen of TCP Monitor Plus focuses entirely on tracing network speed data via a highly readable tab interface.

Traffic Monitor: The default tab displays immediate statistics on your active network adapter. It maps real-time data onto a dynamic, colorful graph.

Live Statistics: It logs your current upload and download transfer rates, maximum reached capacities, average rates, and absolute packet counts.

Adapter Selection: If your machine handles multiple network adapters—such as physical Wi-Fi, Ethernet lines, or virtual VPN interfaces—a simple drop-down menu lets you switch focus instantly. 🔍 Built-In Packet Monitor

Unlike many basic monitors that require a separate utility like Wireshark or WinPcap to look closely at traffic, TCP Monitor Plus includes an internal packet sniffing module.

On-Demand Capture: It runs purely on-demand via a manual “Start” button to protect your system memory from heavy data bloat.

Address Visibility: While capturing, it registers every local and remote IP address, alongside the specific communications ports active on the machine.

Hostname Resolution: A targeted toggle checkbox prompts the software to try matching raw remote IP numbers back to clear hostnames (DNS lookup). 🛠️ Integrated IP Tools Suite

Beyond passive traffic oversight, the application saves engineering time by embedding five standard network utility commands directly into consecutive UI tabs: IP Utility Tool Primary Function Session Monitor

Lists every active connection currently binding your system to external servers, noting which local programs hold open lines. Ping

Tests direct connection availability to a remote host and measures response latency over time. Traceroute

Maps the actual pathway of server hops your data travels across to reach an online target. Whois

Queries registration databases to identify ownership details, registration origin, and contact info for a specific domain name or IP. NSLookup

Tests local and global Domain Name System settings to see how URLs translate into direct numerical internet routing paths. 🚀 Who Is This Tool Best For?

TCP Monitor Plus fills a crucial gap for network administrators, system troubleshooters, and power users. If standard Windows Task Manager graphs are too basic, but enterprise alternatives like Sysinternals TCPView lack active diagnosis options (like Ping and Whois), this all-inclusive tool offers a fast, zero-footprint response mechanism.
