Host Grapher is a very simple collection of Perl scripts that provide graphical display of CPU, memory, process, disk, and network information for a system. There are clients for Windows, Linux, FreeBSD, SunOS, AIX and Tru64. No socket will be opened on the client, nor will SNMP be used for obtaining the data.
Check Website is a performance monitoring and uptime notification tool. It will check if a Website is up, and check the response time of the site. The administrator can then choose to receive an email notification if the site is down, or if the site response time is too slow. All results are also written to a daily log file.
Reliable Response Notification provides guaranteed delivery of critical messages to a wide range of devices. It guarantees that every emergency will have one, and only one, person responding and taking charge of the recovery. For integrated services, like some network monitors, help-desk packages, and security suites, Reliable Response Notification allows the user to update records via their mobile devices. It is available as either a standalone server or as a hosted service.
