TWSNMP FK is a next-generation Network Management System. It combines the performance of Go, the simplicity of Svelte, and the seamless desktop experience of Wails to provide a lightweight yet powerful observability tool.
Ultra lightweight SNMP manager. To keep maps and event logs, etc. always visible. It is designed to be used in Windows kiosk mode. Of course, it can also be used as a normal application.
The following functions will work
- Network map
- Node list
- Polling (PING/TCP/HTTP/NTP/DNS/SNMP/gNMI)
- Event log
- Syslog reception
- SNMP TRAP reception
- ARP monitoring
- MIB browser
- PING Confirmation
- Panel Display
- Host resource MIB display
- Wake On LAN support
- HTML e-mail notification, periodic report
- AI Analysis
- NetFlow/IPFIX
- sFlow
- gNMI
- PKI (CA and CRL/OCSP/ACME/SCEP server)
- SSH Server
- TCP Log server
- OpenTelemetry collector
- MCP Server
- MQTT Server and Polling
The following environment is used for development
- go 1.24 or higher
- wails 2.9.3 or higher
- nsis
- go-task
You can build it with the following command.
task
Double-click from the built executable file to drive it as a normal application. It can also be started from the command line by specifying the following parameters
