I-Nex gathers information for hardware components available on your system and displays it using an user interface similar to the popular Windows tool CPU-Z. It can display information for CPU, GPU, Motherboard, Sound, Hard disks, RAM, Network, and USB, as well as some system information like the hostname, Linux distribution and version, Xorg, GCC, and GLX versions, and Linux Kernel. It can also generate a report on which you can select what to include and optionally send the report to a service such as Pastebin (and others). It also features an option to take a screenshot of the I-Nex window directly from the application.
GroundWork Monitor Community Edition can give you insight into your computing infrastructure, allowing you to see the current and historical states of all your computers: servers, desktops, and laptops, all of your network devices, all of your services (like TCP/IP and Web services), and all of your applications (like mail servers and database apps). You can choose to be alerted when something goes awry via pager, SMS, email, or phone, and even set up automatic restarts or fall-overs.
