A great solution for monitoring hosts (with alerting), measuring your network performance, and quickly diagnosing network problems. Its most powerful component is NetWatch with graphical multiping, alerting capabilities, and a history of response time and packets lost (for monitoring the availability of your hosts). NetTools also includes other popular tools like ping, fast trace (full trace in 1 second), lookup, port scanner, network scanner, and SNMP browser. What makes NetTools unique, is the fact that it has the most highly intuitive user interface.
All tools are very fast and run simultaneously. NetTools may run in icon tray to continuously monitor hosts.
