Cluster health recommendations

From Red Hat Hybrid Cloud Console, you can use the Red Hat Lightspeed advisor service to assess and monitor the health of your OpenShift Container Platform clusters.

The Lightspeed advisor service checks your OpenShift Container Platform clusters against Red Hat best practices and highlights service availability, fault tolerance, performance, and security risks. Its recommendations help you avoid potential problems or solve problems quickly without unplanned downtime.

Each recommendation describes a detected issue, its total risk, the affected clusters, and, where applicable, steps to resolve the issue.

To use the Lightspeed advisor service, register your clusters with OpenShift Cluster Manager.

Display potential issues with your cluster

You can view Red Hat Lightspeed advisor results in Red Hat Hybrid Cloud Console to identify availability, stability, performance, and security issues that affect your OpenShift Container Platform clusters.

Before you begin

  • A cluster registered with OpenShift Cluster Manager
  • Remote health reporting enabled, which is the default
  • Access to Red Hat Hybrid Cloud Console

About this task

The Lightspeed advisor service repeatedly analyzes your clusters and shows the latest results. These results can change, for example, if you fix an issue or the service detects a new issue.

Procedure

  1. In Red Hat Hybrid Cloud Console, go to OpenShift > Fleet management > Advisor > Recommendations.

    Depending on the result, the page displays one of the following:

    • A list of issues that the service detected, grouped by total risk: critical, important, moderate, and low
    • No matching recommendations found, if the service didn't identify any issues
    • No clusters yet, if the service hasn't analyzed the cluster yet. The analysis starts shortly after you install, register, and connect the cluster to the internet.
  2. If the service displays any issues, expand an entry to view more details.

    Depending on the issue, the details might also contain a link to more information.

Display all Red Hat Lightspeed advisor recommendations

By default, the Recommendations page shows only the enabled recommendations that affect your clusters. You can remove the default filters to browse every recommendation in the Red Hat Lightspeed advisor service.

Before you begin

  • A cluster registered with OpenShift Cluster Manager
  • Remote health reporting enabled, which is the default
  • Access to Red Hat Hybrid Cloud Console

Procedure

  1. In Red Hat Hybrid Cloud Console, go to OpenShift Fleet management Advisor Recommendations.
  2. Remove the Clusters impacted and Status filters by clicking the X on each.
    The list shows all recommendations, including ones that don't affect your clusters and ones you disabled.

Red Hat Lightspeed advisor recommendation filters

The Red Hat Lightspeed advisor service can return a large number of recommendations. To focus on your most critical recommendations, you can apply filters to the advisor recommendations list to remove low-priority recommendations.

By default, filters are set to only show enabled recommendations that are impacting one or more clusters. To view all or disabled recommendations in the Red Hat Lightspeed library, you can customize the filters.

To apply a filter, select a filter type and then set its value based on the options that are available in the drop-down list. You can apply multiple filters to the list of recommendations.

You can set the following filter types:

  • Name: Search for a recommendation by name.
  • Total risk: Select one or more values from Critical, Important, Moderate, and Low indicating the likelihood and the severity of a negative impact on a cluster.
  • Impact: Select one or more values from Critical, High, Medium, and Low indicating the potential impact to the continuity of cluster operations.
  • Likelihood: Select one or more values from Critical, High, Medium, and Low indicating the potential for a negative impact to a cluster if the recommendation comes to fruition.
  • Category: Select one or more categories from Service Availability, Performance, Fault Tolerance, Security, and Best Practice to focus your attention on.
  • Status: Click a radio button to show enabled recommendations (default), disabled recommendations, or all recommendations.
  • Clusters impacted: Set the filter to show recommendations currently impacting one or more clusters, non-impacting recommendations, or all recommendations.
  • Risk of change: Select one or more values from High, Moderate, Low, and Very low indicating the risk that the implementation of the resolution could have on cluster operations.

Filter Red Hat Lightspeed advisor recommendations

As an OpenShift Cluster Manager cluster manager, you can filter the recommendations that are displayed on the recommendations list. By applying filters, you can reduce the number of reported recommendations and concentrate on your highest priority recommendations.

Procedure

  1. Go to Red Hat Hybrid Cloud Console OpenShift Advisor recommendations.
  2. In the main, filter-type drop-down list, select the Category filter type.
  3. Expand the filter-value drop-down list and select the checkbox next to each category of recommendation you want to view. Leave the checkboxes for unnecessary categories clear.
  4. Optional: Add additional filters to further refine the list.
