GNMS is a network management system, a graphical tool used to monitor the state of network elements. Monitoring can be done in multiple ways using service discovery, SNMP, WMI, and custom plugins. Syslog and SNMP traps can be caught too.
System Monitor is a little tool made to ease monitoring of servers and processes. It provides you with the ability to create as many terminals as you want, and name and pack them in any order you like. You can, of course, specify what command each terminal will fork.
