Manage Tuning Profiles

Introduction

As a system administrator, you are responsible for optimizing the performance of the systems under your care. One important aspect of this is managing tuning profiles, which allow you to customize the system's behavior to meet specific requirements. In this challenge, you will learn how to create, activate, and verify a custom tuning profile on a Red Hat Enterprise Linux (RHEL) system.

Create a Custom Tuning Profile

Tasks

• Create a custom tuning profile named "myprofile" in the appropriate directory.
• Add a setting to the profile that increases the maximum number of open files.

Requirements

• The custom tuning profile must be created in the /etc/tuned/ directory.
• The profile must be named myprofile.
• The profile must include a setting that increases the maximum number of open files to at least 4096.
• All operations must be performed as the labex user.

Example

After creating the custom tuning profile, the contents of the /etc/tuned/myprofile/tuned.conf file should look similar to the following:

[main]
include=balanced

[files]
/etc/security/limits.conf=/etc/tuned/myprofile/limits.conf

The /etc/tuned/myprofile/limits.conf file should contain the following line:

* soft nofile 4096
* hard nofile 4096

Summary

In this challenge, you learned how to create a custom tuning profile on a Red Hat Enterprise Linux system. You created a profile named "myprofile" in the /etc/tuned/ directory, and added a setting to increase the maximum number of open files. By managing tuning profiles, you can optimize the performance of your systems to meet specific requirements. This knowledge is essential for system administrators working with Red Hat Enterprise Linux.
