Tools to Install

Script checks for each tool before installing. Uses winget with a direct-download fallback.

Scheduling

Task trigger

Run mode

Run Setup-MonitorStation.ps1 as Administrator. Wireshark installs Npcap which requires elevation.

Install Tools Script

Just the tool installation portion - Wireshark, Speedtest CLI, PingInfoView, WinMTR. No monitors, no scheduled tasks. Useful for prepping a machine before deploying the monitors.

Log file

Jitter = average absolute deviation between consecutive RTT samples. Microsoft Teams thresholds: jitter under 30 ms, latency under 100 ms, packet loss under 1%.

Quick port scan on new device

Run the setup script once on a clean, trusted network to build the baseline. Devices detected after that point will trigger alerts.

All active adapters

Uses Get-NetAdapterStatistics. CRC errors = physical layer problem (bad cable, SFP, switch port). Discards = congestion or buffer issues. Counters are delta-per-interval.

Interface errors

Skip if no issues

SMTP password is not stored in the script. The script prompts on first run and saves a SecureString to a .cred file using Windows DPAPI (machine-specific, not portable).

Green dot = module included. Configure each tab, then generate. You get one script - copy it to the target machine and run as Administrator. It writes all module scripts to disk itself, installs tools, registers scheduled tasks, and starts the monitors.

Load Log Files

Drop one or more log files generated by the monitoring scripts. File type is auto-detected from the filename.
