ServersCheck Monitoring Free Edition is a tool for monitoring, reporting and alerting on network and systems availability. The standard version can be used for free with up to 15 devices, which is probably more than adequate for personal use. It can monitor any TCP Port (HTTP, HTTPS, FTP, NNTP, POP3, SMTP, VNC, DNS, etc.), check ODBC, Oracle, MySQL databases, trap SNMP values (disk space, free memory, CPU usage,...), verify content served from a web server and check NT services and process availability. In addition, it also can monitor environmental devices like temperature, humidity, flooding. Alerting can be done via email, MSN or network message. ServersCheck Monitoring runs as a local service and is administrated through a browser interface by connecting to the built-in web server. Additional features include alerts and graph output for long-term statistics tracking.
