Chapter 1. Using comparisons in your Insights for Red Hat Enterprise Linux inventory to perform drift analysis

You can analyze and troubleshoot components of your Insights for Red Hat Enterprise Linux inventory and perform drift analysis by examining and comparing your system configurations.

1.1. Comparing system configurations in your Red Hat Insights inventory

The drift service enables you to compare the system configuration of one system to other systems in your Insights for Red Hat Enterprise Linux inventory. You can also compare system configurations over time to track and analyze changes. In addition, you can set a reference point and compare it to the states of all your systems. You can use any of these comparisons to troubleshoot systems at various points in time.

When comparing configurations across different systems, you can filter profile facts and system tags to highlight configurations that match, or to see where they differ. You can also see which systems have missing or incorrect information.

You can also define and manage baselines. You can use defined baselines in your Insights for Red Hat Enterprise Linux inventory to compare baselines and system configurations. In addition, you can generate a comma-separated values (CSV), or JavaScript Object Notation (JSON) output of the systems and baselines you are comparing.

1.2. User Access for drift service users

Before you can access certain features in the Red Hat Insights for Red Hat Enterprise Linux application, you must have the correct permissions, which are granted in Red Hat Hybrid Cloud Console > User Access > Groups. An Organization Administrator or User Access administrator must add you as a member to a User Access group with the required roles.

By default, User Access on the Red Hat Hybrid Cloud Console has preconfigured a Drift analysis administrator role (all access) and a Drift viewer role (read-only access). If your organization determines that the default roles provide insufficient access, a User Access administrator can configure a custom role to provide the specific permissions that your users require.

The following sections in this chapter describe each of the default roles for drift service users.

Important

Changes to User Access must be performed by an Organization Administrator on your Red Hat account, or by an account user who is a member of a User Access group with the User Access administrator role.

1.2.1. Drift analysis administrator role

The Drift analysis administrator role is a default role in the Default admin access group. In its default configuration, members of a group with the Drift analysis administrator role can perform any available operation on drift resources.

Note

If the Default access group has previously been modified, these changes will not be applied to it. If you configured groups before October 2022, any user who is not an organization administrator will have the Drift analysis administrator role replaced with the Drift viewer role.

1.2.2. Drift viewer role

The Drift viewer role is a default role in the Default admin access group. All Insights for Red Hat Enterprise Linux users on your account are members of the Default access group. The Drift viewer role provides read only access. If your organization determines that the default configuration of the Drift viewer role is inadequate, a User Access administrator can create a custom role with the specific permissions required.

Note

If the Default access group has previously been modified, these changes will not be applied to it. If you configured groups before October 2022, any user who is not an organization administrator will have the Drift analysis administrator role replaced with the Drift viewer role.
