Monitor Clusters

  • Capella Operational
  • concept
    +
    Couchbase Capella provides cluster metrics, activity logs with events, and alerts to notify you of critical cluster health events.

    Cluster Metrics

    Cluster metrics help you monitor the current and past performance of your cluster. You can view cluster metrics using the Monitoring dashboard. The Monitoring dashboard allows you to choose what metrics to track and chart this data over specified time frames or close to real-time. You can zoom in on time frames using your mouse to drag-to-select on a chart or through the time controls on the dashboard.

    Activity Logs

    The Activity Logs in Capella provide a complete auditable timeline of events occurring in your organization, projects, and clusters. Each event in an Activity Log includes a summary of the activity, severity, resource affected, actor, and when it occurred. Filtering allows you to narrow down what events appear in an Activity Log based on clusters, projects, users, severity, tag, and date. In Capella, you can view an Activity Log for your organization, each project, and each cluster.

    Events

    Events are items written to Activity Logs that reflect specific conditions in your Capella organization, project, and cluster. Events can include service-affecting conditions to user activity.

    For a list of the events and alerts in Capella, see Alert Reference.

    Event Severity

    Each event that Capella emits includes a severity level. The following table describes the event severity levels in Capella:

    Severity Description Sends alert

    Info

    Informational events. Events with an info severity range from user activities to regular cluster operation tasks.

    Warning

    Unexpected issues that affect performance or cause other problems that may need intervention. Events with a warning severity often indicate a cluster is trending towards more critical thresholds.

    ✔

    Critical

    Availability affecting events that require immediate intervention. Most events with a critical severity occur due to cluster resource usage exceeding critical utilization thresholds.

    Event Tags

    Each event in Capella has one or more tags. Tags categorize events, allowing you to filter events. The following table lists each available tag type:

    Tag Description

    To resolve an alert, improve the immediate conditions producing the related event.

    Activity Logs keep a record of all past events, including those that generate alerts.
