How to Install Collectl on OpenBSD

Collectl is a performance monitoring utility for Linux and other Unix-like systems. In this tutorial, we will guide you through the installation process of Collectl on OpenBSD.

Prerequisites

Before installing Collectl, make sure your OpenBSD system has the following requirements.

• Internet connectivity
• Command-line access with root privileges
• Perl version 5.8 or later

Step 1: Install CPAN

CPAN (Comprehensive Perl Archive Network) is a package manager for Perl. It allows you to install Perl modules and their dependencies from a central repository.

To install CPAN, open the terminal and run the following command as root:

pkg_add p5-CPAN

Step 2: Install Required Perl Modules

Collectl requires several Perl modules to run properly. You can install these modules by running the following command:

cpan -i Getopt::Long IO::Handle Term::ReadKey Time::HiRes

This command installs the following Perl modules:

• Getopt::Long - Perl module for parsing command-line options
• IO::Handle - Perl module for file input/output handling
• Term::ReadKey - Perl module for reading keyboard input
• Time::HiRes - Perl module for high-resolution time measurements

Step 3: Download and Install Collectl

You can download the latest version of Collectl from its official website. For example, to download version 4.3.1, run the following command:

fetch http://downloads.sourceforge.net/project/collectl/collectl/collectl-4.3.1/collectl-4.3.1.src.tar.gz

After downloading, extract the tarball using the following command:

tar -xzf collectl-4.3.1.src.tar.gz

This creates a directory named "collectl-4.3.1" in your current working directory. Change to this directory:

cd collectl-4.3.1

Next, run the following command to install Collectl:

perl -MExtUtils::MakeMaker -e 'MY->fixin(shift)' . && make && make install

This command runs the ExtUtils::MakeMaker Perl module to generate the Makefile for Collectl, and then compiles and installs the software.

Step 4: Verify Collectl Installation

To verify that Collectl is installed properly, run the following command:

collectl --version

This command should display the version number of Collectl, indicating that the software is installed correctly.
