Nagios Made Easy..

by Shelly King on July 17th 2009 at 04:43 PM

Nagios gives you an unbeatable overview of all your machines, meaning that you can fix upcoming problems before they turn critical and be certain that you're not missing anything about your network. The basic structure of Nagios is pretty simple: you set up one machine as your Nagios server, and it gathers information on the client machines you point it at, then displays it in a neat web page format. Read on to learn how to get started with Nagios on your own network!

You can get basic service information on the client machines (whether they're pingable, whether SSH is OK, whether HTTP is OK) without needing to install any software on them; the server alone will do the work. Or you can get centralised reports on further information (such as disk space or CPU usage), if you install client-side software. The server can react to alert situations by sending email or text to inform a human person, or by doing more or less anything else that you can write a script to make happen.

Web-based Network Monitoring Made Easy (and Free!)

by Randy Clark on April 24th 2008 at 01:53 AM

Easy to set up. Monitors several services like httpd out of the box. Several plugins available too, to extend the offering to monitor other services.

Out of the box, it shows, with status indications, the current load, the current number of users, a ping report, information on the root partition, the swap usage, ssh reports, total processes, etc.

You can monitor boxes locally, or have them be remotely monitored for a consolidated overview.

GroundWork Launches MonitoringForge.org for Monitoring Tools

GroundWork Open Source, which provides commercial open source network management software, has announced the launch of MonitoringForge.org, which it bills as a "unified hub for open source monitoring." While the site is primarily aimed at IT administrators who want to compare open source system and network monitoring tools to proprietary alternatives, it may also serve several useful purposes for open source project leaders that don't have community web sites and need to automate aspects of projects. Here are more details.

Over 15 Top Open Source Tools for Web Developers

Recently, we covered research showing that nearly half of open source developers are focused on applications for delivery in the cloud. Software as a Service (SaaS) applications are increasingly either employing open source or are built entirely on it. And all of this adds up to an increasing premium on web development skills and good tools for web development in the open source community. The good news is that there are many open source tools to help you with your web project, and given the costs of web development environments and the like, they can save you a lot of money. Here are over 15 good examples of tools and tutorials, with a few that we've covered before appended at the end, in case you missed them.
