Chapter 8. Using observability with Red Hat Insights

download PDF

Red Hat Insights is integrated with Red Hat Advanced Cluster Management observability, and is enabled to help identify existing or potential problems in your clusters. Red Hat Insights helps you to identify, prioritize, and resolve stability, performance, network, and security risks. Red Hat OpenShift Container Platform offers cluster health monitoring through OpenShift Cluster Manager. OpenShift Cluster Manager collects anonymized, aggregated information about the health, usage, and size of the clusters. For more information, see Red Hat Insights product documentation.

When you create or import an OpenShift cluster, anonymized data from your managed cluster is automatically sent to Red Hat. This information is used to create insights, which provide cluster health information. Red Hat Advanced Cluster Management administrator can use this health information to create alerts based on severity.

Required access: Cluster administrator

8.1. Prerequisites

  • Ensure that Red Hat Insights is enabled. For more information, see Modifying the global cluster pull secret to disable remote health reporting.
  • Install OpenShift Container Platform version 4.0 or later.
  • Hub cluster user, who is registered to OpenShift Cluster Manager, must be able to manage all the Red Hat Advanced Cluster Management managed clusters in OpenShift Cluster Manager.

8.2. Red Hat Insights from the Red Hat Advanced Cluster Management console

Continue reading to view functionality descriptions of the integration:

  • When you select a cluster from the Clusters page, you can select the Number of identified issues from the Status card. The Status card displays information about Nodes, Applications, Policy violations, and Identified issues. The Identified issues card represents the information from Red Hat insights. The Identified issues status displays the number of issues by severity. The triage levels used for the issues are the following severity categories: Critical, Major, Low, and Warning.
  • After you click the number, the Potential issue side panel is displayed. A summary and chart of the total issues are displayed in the panel. You can also use the search feature to search for recommended remediations. The remediation option displays the Description of the vulnerability, Category that vulnerability is associated with, and the Total risk.
  • From the Description section, you can select the link to the vulnerability. View steps to resolve your vulnerability by selecting the How to remediate tab. You can also view why the vulnerability occurred by clicking the Reason tab.

See Managing insight PolicyReports for more information.

8.3. Managing insight PolicyReports

Red Hat Advanced Cluster Management for Kubernetes PolicyReports are violations that are generated by the insights-client. The PolicyReports are used to define and configure alerts that are sent to incident management systems. When there is a violation, alerts from a PolicyReport are sent to incident management system.

8.3.1. Searching for insight policy reports

You can search for a specific insight PolicyReport that has a violation, across your managed clusters. Complete the following steps:

  1. Log in to your Red Hat Advanced Cluster Management hub cluster.
  2. Click the Search icon in the console header to navigate to the Search page.

  3. Enter the following query: kind:policyreport.

    Note: The PolicyReport name matches the name of the cluster.

  4. You can specify your query with the insight policy violation and categories. When you select a PolicyReport name, you are redirected to the Details page of the associated cluster. The Insights sidebar is automatically displayed.

  5. If the search service is disabled and you want to search for an insight, run the following command from your hub cluster: 

    oc get policyreport --all-namespaces

8.3.2. Viewing identified issues from the console

You can view the identified issues on a specific cluster. Complete the following steps:

  1. Log in to your Red Hat Advanced Cluster Management cluster.
  2. Select Overview from the navigation menu.

  3. Select a severity to view the PolicyReports that are associated with that severity. Details of the cluster issues and the severities are displayed from the Cluster issues summary card.

    1. Alternatively, you can select Clusters from the navigation menu.
    2. Select a managed cluster from the table to view more details.
    3. From the Status card, view the number of identified issues.
  4. Select the number of potential issues to view the severity chart and recommended remediations for the issues.

  5. Click the link to the vulnerability to view steps on How to remediate and the Reason for the vulnerability.

    Note: After the issue is resolved, the Red Hat Insights are received by Red Hat Advanced Cluster Management every 30 minutes, and Red Hat Insights is updated every two hours.

  6. Be sure to verify which component sent the alert message from the PolicyReport.

    1. Navigate to the Governance page and select a specific PolicyReport.
    2. Select the Status tab and click the View details link to view the PolicyReport YAML file.
    3. Locate the source parameter, which informs you of the component that sent the violation. The value options are grc and insights.
