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.

How to install LAMP on ubuntu

Start install Apache:
1. Open the terminal (we will be using it through most of my guide) from Applications > Accessories > Terminal

2. Install apache2 using apt-get by typing the following

Quote : sudo apt-get install apache2

Note that you should know the root password.
Now everything should be downloaded and installed automatically.

To start/stop apache2 write:

Quote : sudo /etc/init.d/apache2 start

Quote : sudo /etc/init.d/apache2 stop

Your www folder should be in: /var/www/

Then install PHP / PHP5:
1. Also in terminal write:

Quote : sudo apt-get install php5 libapache2-mod-php5

Then install MySQL:
1. In terminal execute :

Quote : sudo apt-get install mysql-server

2. (optional) If you are running a server you should probably bind your address by editing bind-address in /etc/mysql/my.cnf and replacing its value (127.0.0.1) by your IP address

3. set your root password (although mysql should ask you about that when installing)

mysql> SET PASSWORD FOR ‘root’@'localhost’ = PASSWORD(‘xxxxxx’);

4. Try running it

mysql -u root -p xxx

where xxx is your password.
Note: You can install PHPMyAdmin for a graphical user interface of MySQL by executing

Qoute : sudo apt-get install libapache2-mod-auth-mysql php5-mysql phpmyadmin

How to include any module in Joomla 1.5

Let's take one example, our Google AdSense module. This can be placed in any module position of the template by default, but not within content. This tutorial shall now explain how to enable it (or any other module) within content in Joomla! 1.5.

STEP 1: Create a new copy of the Module just for in-content use.

Extensions > Module Manager. Check the checkbox before the module in question and click on "Copy" on the top right (see image).

The copy is placed just under the original in the same module position and is unpublished by default. It will be named "Copy of ...".

STEP 2: Open the Module that you just copied.

Now just click on the name of the module (Copy of ...).

STEP 3: Change the "Module Position"

Here, we are going to do something very sleek. With the module opened, look at the left side of the screen. You will see a parameter named "Position". It will have a dropdown combobox in front of it. Joomla! developers have hidden a truly powerful option here. It is "editable". See picture on the right to get a clear idea. So what? Read on...

Let's edit the position name and "create" a new unique position just for in-content use, which will not be shown on the template elsewhere. Do not click on the arrow, but click directly within the textbox of that field and "delete" the content (using delete or backspace key). Now type a new name, let's say content_adsense125 (You can type any name you want, but this to me means that I am using this for showing AdSense ads, 125x125 size for in-content use).

Look at the next picture below for what it will look like. After making the other necessary changes to the module parameters on the right side, "Save" the module. This will now be saved in the "new" position that you just created.As it is a custom position, it will not show on the frontend. That was our purpose too, we want it to show only within content and only where we assign. See the right side ads for an example.

STEP 4: Go to the Plugin Manager

Extensions > Plugin Manager. Look for a plugin named "Content - Load Module". Open it. On the right side, you will see a dropdown box. Click on its arrow and select "No wrapping - raw output" as shown in the next picture.

STEP 5. STEP 6, STEP 7...

Open your content item within which you want to show the module. In the desired location within the article, just type

where"loadposition" is a constant to call the plugin that we just edited in step 4 and "module" is the variable module position to be called, in this case we should change it to content_adsense125 as done in step 3. As indicated above, change only the blue text and leave the red untouched.

Just one word of caution, do not use standard positions like "left" or "user1" inside content. They may load ALL the modules in that position into that content.

From now on, you should be able to place any module in any content of your choice.
