Windows Network
Monitoring
Bandwidth Utilization, TCP Connections & Interface Health
Ensure your Windows server has the bandwidth it needs. BigBell's network monitoring tracks interface traffic, dropped packets, and TCP connections to prevent network bottlenecks.
What is Windows Network Monitoring?
Windows network monitoring is the process of tracking the performance and health of the network adapters (NICs) on a Windows Server. It involves measuring the total Bytes Received and Bytes Sent per second, tracking the number of active TCP/UDP connections, and identifying packet loss or interface errors. This data is collected from the Windows networking stack to provide real-time visibility into data throughput.
Why Windows Network Monitoring Matters
A heavily loaded network interface can severely degrade application performance, especially for data-heavy servers like File Servers (SMB), Database Servers (SQL), or Web Servers (IIS). If a Windows server saturates its available bandwidth, incoming requests will experience high latency or simply drop. Furthermore, monitoring active TCP connections helps identify port exhaustion—a scenario where the server runs out of available ports to establish new outbound connections.
- ✓Detect bandwidth saturation causing application latency
- ✓Identify unusual traffic spikes indicative of DDoS or malware
- ✓Prevent TCP port exhaustion on high-traffic web servers
- ✓Monitor virtual switch performance in Hyper-V environments
Core Use Cases
Network monitoring is essential for diagnosing slow SMB file transfers across corporate networks, ensuring SQL Server has adequate bandwidth to stream large backups, and managing egress traffic costs in cloud environments like Azure or AWS.
Complete Network Monitoring Capabilities
Bandwidth Tracking
Monitor real-time inbound and outbound traffic rates (Megabits per second) across all physical and virtual network adapters.
Packet Error Detection
Track discarded and errored packets to quickly identify failing network cables, bad switch ports, or driver issues.
TCP Connection Metrics
Keep a close eye on the number of Established and Time-Wait TCP connections to proactively prevent ephemeral port exhaustion.
Saturation Alerts
Set alerts to trigger if network interface utilization exceeds 85% of its maximum link speed for a sustained period.
