    Build a custom Monitoring dashboard

    You can build a custom Monitoring dashboard that displays charts of selected Dataplex Universal Catalog service metrics. For more information about how to create a dashboard, see Create and manage custom dashboards . When you select a metric for a widget on your dashboard, select a Cloud Dataplex resource and then choose a Dataplex Universal Catalog metric.

    Use Monitoring alerts

    You can create a Monitoring alert that notifies you when a Dataplex Universal Catalog service or job metric crosses a specified threshold.

    Create an alert

    To create an alert, follow the instructions in Create metric-threshold alerting policies . When you select a time series to be monitored, select a Cloud Dataplex resource and then choose a Dataplex Universal Catalog metric.

    View alerts

    When an alert is triggered by a metric threshold condition, Monitoring creates an incident and a corresponding event.

    To view an incident, follow this step:

    If you defined a notification mechanism in the alert policy, such as an email or SMS notification, Monitoring also sends a notification of the incident.

    For more information about alerts, see Incidents for metric-based alerts .
