Monitor the status and top issues of your Kubernetes environment

Use the Kubernetes overview page for a high-level understanding of your Kubernetes environment.

Monitor the status and top issues of your Kubernetes environment with the Kubernetes overview page.

Use the Kubernetes overview page to:

  • Understand the count and percentage of entity types in your environment.

  • Monitor the status of the nodes and pods in your environment at a glance.

  • View the top issues for your Kubernetes entities over time.

Prerequisites

To monitor Kubernetes instances with the Kubernetes overview page, you must meet the following requirements.

  • You have configured data collection from Kubernetes. For instructions, see Collect Kubernetes data.
    Note:

    This feature requires the metrics and dimensions collected by default with the Collector for Kubernetes. For more information, see Collected metrics and dimensions for Kubernetes.

  • You have a user role with the following permissions:

    • READ_NAVIGATOR: Required for viewing navigator data.

    • EXECUTE_SIGNAL_FLOW: Required for running SignalFlow API calls.

    • READ_ALERT: Required for viewing alerts. Without this permission, the page will still load but inline alerts will not be visible.

Monitor the top issues in your Kubernetes environment

On the Kubernetes overview page, the Top issues section displays tabs that you can use to identify issues with your Kubernetes environment.

The following table describes the Top issues tabs and the threshold for each issue.

Issue name Threshold
Degraded deployments The deployment has fewer pods available than desired pods.
Failed jobs The job completion status is Failed.
