SMonitor is a network monitoring software that allows you to verify the network connectivity of TCP/IP hosts on the Internet and LAN. The program periodically ping, or checks TCP and UDP ports on user specified computers or other network devices. If the destination host fails to reply to a ping, connection request, or user datagram, sMonitor alerts you using audible alarm, visible notification, e-mail message, third-party software, modem and telnet connections. Also, the program generates log file, CSV format file, creates and uploads by FTP the HTML file, which reflects a current status. Based on test result, the program can operate remote systems (power management, reboot, alarm reporting) by modem and telnet using custom scripts. sMonitor can run as standard Windows application or NT service.
