Five Free Tools for Multi-Monitor Computer Set-Ups

As a developer or designer, it is often helpful to have multiple monitors to increase the amount of screen real estate you have, which in turn can lead to higher productivity. For instance, you may have one screen as your primary monitor where you perform your work, and another one that has your email client, Skype, IM client, Twitter client, and other communication apps that you can easily monitor and switch to.

We’d like to share several freeware and open source tools available for download to help you harness the power of multi-display set ups and get you up and running quickly. We hope that you might find the perfect application for you!

Synergy

Synergy is an open source software application that lets users of multi-monitor workstations share a mouse and keyboard between several displays. All you have to do is move the mouse cursor off the edge of one display to have it on another adjacent display. It also creates a single virtual clipboard to allow the copy and pasting across the many displays. With Synergy comes a handy module for synchronizing your screensavers across multiple displays so that they run in tandem. If there is a password required after screensaver mode, you only have to type in the password into one monitor to activate all the others. There is also a fork of Synergy called Synergy+ that you can check out on Google Code.

Input Director

Input Director grants you the ability to use a single keyboard and mouse on a multi-computer set up, making it the ideal solution for networked computers, a common situation where professionals have more than one computer (such as a desktop and laptop). All you have to do is move the pointer off the edge of the display and it appears on the adjacent monitor on that side, making it the active monitor.

UltraMon

UltraMon is a great tool for multi-display computer configurations that can support up to 10 monitors. It allows you to set custom features for each monitor such as resolution, wallpaper, and taskbar settings. UltraMon allows for the moving of running programs from the primary display to the secondary (and vice versa). Each of the monitors will have their own taskbar showing you the applications running on them. You can predefine and save monitor settings, as well as position where a program opens from the shortcut menu to help speed up your workflow. It also has a feature for easily turning off secondary monitors to conserve electricity consumption when you don’t need them and to reduce distraction when they’re not in use.

Multi Monitor Mouse (M³)

This app saves you from the hassle of having to drag your mouse off the desk as you try to get to the farthest monitor in a multi monitor environment. It immediately warps your cursor across the borders of the display on demand and runs in the background to avoid taxing the systems resources. It is accessible from the system tray where you can change the settings at will. It also speeds up mouse targeting by an estimated 30%.

MultiMon Taskbar

MultiMon Taskbar lets you have unique taskbars for each monitor, helping you to easily organize your applications across multiple computer screens. It has a move-to-monitorbutton accessible from all Windows programs for convenience and ease of movement from one monitor to another. In addition, MultiMon has a clipboard extender module for synchronizing your clipboards across multiple displays, making copy and pasting between networked computers a breeze.

10 Free Server & Network Monitoring Tools

Top 10 server/network monitoring tools. You will see a variety of server applications here so that you might find the tool (or tools) for your needs.

1. Monit

Monit not only monitors your server, but also attempts to remedy problems by taking predefined actions for certain situations. For example, if your database server crashes, Monit can automatically restart the service if this is the action that you want to take (hint: it usually is).

If you have more than one server that you need to monitor, then you can useM/Monit- an extended version of Monit that provides a simple way to monitor multiple machines.

There’s also an iPhone app available for M/Monit to help you conveniently check on your network without lugging around a laptop around.

2. Ganglia

When you have a cluster of machines, it’s difficult to see how the whole cluster is doing all at once. Ganglia, instead, presents an overview of the whole cluster. This is a great tool to have set up when you’re working with a server cluster; with that said, it may be overkill for single-machine set-ups.

3. Munin

Munin monitors and graphs system performance metrics. It can automatically produce daily/weekly/monthly/yearly performance graphs and reports of many important metrics. It comes with the ability to monitor core system resources, such as memory, disk space, CPU usage, server applications such as MySQL, Apache, and Squid.

One of Munin’s greatest strengths is how simple it is to extend. With just a few lines of code, you can write a plugin to monitor almost anything. Being so easy to extend means that Munin is also a good choice for graphing things unrelated to server performance, such as the number of user signups or website popularity.

4. Cacti

Cacti is similar to Munin in many ways. What is makes Cacti different though–and where it stands out in relation to Munin–is that it allows you to resize your graphs and view data for an arbitrary range. Whereas Munin has fixed daily, weekly, monthly and yearly graphs (unless you write a custom extension), Cacti lets you view your data however you want to: last 2 hours, last 4 days, last 6 months, out of the box. You can even visually select and zoom into regions on your graphs.

5. Nagios

Nagios is "the industry standard in IT infrastructure monitoring,"–well, at least that’s what it says on their website. Nagios can be complicated to install and configure, but its wealth of features are unmatched by any tool out in the market and is geared for the experienced IT network administrator. Nagios supports monitoring of multiple hosts and can send out alerts via email, pager (if you still use this ancient technology) or SMS/text messaging. Like Monit, it can also be configured to automatically respond to problems.

6. Zabbix

Zabbix is a feature-packed monitoring tool. It has great visualization support including user-defined views, zooming, and mapping. It can send out alerts via email, SMS or instant message. It also provides audible alerts, which can be useful when you’re physically near the monitoring machine.

7. ObserverNMS

ObserverNMS is geared towards Linux, BSD and Cisco networks. It supports auto discovery of your network infrastructure, finding the networks that you’re likely interested in monitoring; this feature can be compared to how your Wi-Fi software automatically finds signals in range that you can jack into. ObserverNMS provides detailed graphs, and can be set up alongside Nagios to provide alerts. It also integrates well with Collectd (featured below) for a more robust interface.

8. Zenoss

Zenoss is an open source version of the commercial server monitoring tool Zenoss Enterprise, written entirely in Python. It supports the Nagios plugin format, so many existing Nagios plugins can be used in Zenoss. One of the main highlights of Zenoss is its powerful yet simple to use user interface.

9. Collectd

Collectd is similar to Munin and Cacti in that it focuses on graphing system metrics. Where it excels in is that it is designed specifically for performance and portability; this ultimately means it’s great on rugged systems, low-end systems, and embedded systems. Being designed for performance and low-system resource use means that Collectd can gather data every 10 seconds without interfering with your server processes, providing extremely high-resolution statistics. You can write extensions for it in C, Perl or Java.

10. Argus

Argus focuses on the monitoring of network services, and supports IPv4 and IPv6. It has a nice alert escalation procedure: after sending out an alert and the problem still isn’t resolved within a fixed amount of time (because the systems admin is at home enjoying his sleep), another alert will be sent out to someone else.
