<span style="font-family: Open Sans;"><span style="font-size: 14px;">The Comprehensive Perl Archive Network (CPAN) is a repository of over 250,000 software modules and accompanying documentation for 39,000 distributions, written in the Perl programming language by over 12,000 contributors.</span></span></div>
<div>
<span style="font-family: Open Sans;"><span style="font-size: 14px;"><br /></span></span></div>
<div>
<span style="font-family: Open Sans;"><span style="font-size: 14px;">The modules can be downloaded from metacpan.org as well as mirrored sites worldwide.CPAN can denote either the archive network itself, or the Perl program that acts as an interface to the network and as an automated software installer (somewhat like a package manager). Most software on CPAN is free and open source software.</span></span></div>

This is very simple for one module with no dependencies. Typically, Perl modules will be dependent on several other modules. Chasing all these dependencies one-by-one can be very painful and annoying task. I recommend the CPAN method of installation as shown below. Use the manual method only if the server is not connected to the Internet.</div>

To install Perl modules using CPAN, make sure the cpan command is working. You should have the CPAN perl module installed before you can install any other Perl modules using CPAN. In this example, CPAN module is not installed.</div>

<span style="font-weight: normal;"><span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Apache Cassandra is an open source distributed database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure. Cassandra offers capabilities that relational databases and other <a href="http://www.hackthesec.co.in/search/label/nosql_database">NoSQL</a> databases simply cannot match such as: continuous availability, linear scale performance, operational simplicity and easy data distribution across multiple data centers and cloud availability zones. Cassandra’s architecture is responsible for its ability to scale, perform, and offer continuous uptime. Rather than using a legacy master-slave or a manual and difficult-to-maintain shared architecture, Cassandra has a masterless "ring" design that is elegant, easy to setup, and easy to maintain.</span></span></span></h1>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Atop is an ASCII full-screen performance monitor for Linux that is capable of reporting the activity of all processes (even if processes have finished during the interval), daily logging of system and process activity for long-term analysis, highlighting overloaded system resources by using colors, etc. At regular intervals, it shows system-level activity related to the CPU, memory, swap, disks (including LVM) and network layers, and for every process (and thread) it shows e.g. the CPU utilization, memory growth, disk utilization, priority, username, state, and exit code.</span></span><br />
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">In combination with the optional kernel module netatop, it even shows network activity per process/thread.</span></span><br />
