Red Hat Customer Content Services

Abstract


Chapter 1. About Insights Advisor

Use Insights Advisor to identify and solve issues with your clusters.

1.1. Understanding Insights Advisor

Insights Advisor analyzes your cluster and helps you to identify potential issues that it may be exposed to, and displays them inside of OpenShift Cluster Manager. You can then use this information to proactively identify and respond to issues that may affect security, performance, availability, and stability.

Once a potential issue is detected, Insights Advisor will assess and categorize the risk as Low, Moderate, Important, or Critical. Depending on the issue, the details may also contain a link to a Red Hat Knowledge Base article or possible remediation steps. See Section 2.1, “Displaying potential issues with your cluster” for more information.

Chapter 2. Using Insights Advisor

Insights Advisor repeatedly analyzes the data Insights Operator sends. You can view and manage reports showing Insights Advisor data for your OpenShift Container Platform cluster on the Insights Advisor tab of each cluster in OpenShift Cluster Manager.

2.1. Displaying potential issues with your cluster

This section describes how to display the Insights Advisor report in OpenShift Cluster Manager.

Note that Insights Advisor repeatedly analyzes your cluster and shows the latest results. These results can change, for example, if you fix an issue or a new issue has been detected.

Prerequisites

Procedure

  1. Click the Clusters menu in the left pane.
  2. Click the cluster’s name to display the details of the cluster.
  3. Open the Insights Advisor tab of the cluster.

    • A list of issues Insights has detected, prioritized by risk (low, moderate, important, and critical).
    • No health checks to display, if Insights has not yet analyzed the cluster. The analysis starts shortly after the cluster has been installed and connected to the internet.
  4. If any issues are displayed on the tab, click the > icon in front of the entry for further details.
