Cloud Monitoring provides visibility into the performance, uptime, and overall health of cloud-powered applications. Google Cloud's operations suite collects and ingests metrics, events, and metadata from Dataplex services to generate insights via dashboards and charts.

Access service metrics in Monitoring

Dataplex service resource metrics are automatically enabled on Dataplex services. Use Monitoring to view these metrics.

You can access Monitoring from the Google Cloud console or by using the Monitoring API.

Console

  1. In the Google Cloud console, go to the Cloud Monitoring > Metrics explorer page:

    Go to the Metrics explorer page

  2. From the "Find resource type and metric" drop-down list, select a Cloud Dataplex resource.

  3. Click again in the input box, and then select a metric from the drop-down list. Hovering over the metric name displays information about the metric.

You can select filters, group by metric labels, perform aggregations, and select chart viewing options.

REST

You can use the Monitoring timeSeries.list API to capture and list metrics defined by a filter expression. Use the Try this API template on the API page to send an API request and display the response.

Build a custom Monitoring dashboard

You can build a custom Monitoring dashboard that displays charts of selected Dataplex service metrics.

  1. Select + CREATE DASHBOARD from the Monitoring Dashboards Overview page. Provide a name for the dashboard, then click Add Chart in the upper-right menu to open the Add Chart window. Select a Cloud Dataplex resource as the resource type. Select one or more metrics and metric and chart properties. Then Save the chart.

  2. You can add additional charts to your dashboard. After you Save the dashboard, its title appears in the Monitoring Dashboards Overview page. Dashboard charts can be viewed, updated, and deleted from the dashboard display page.

Use Monitoring alerts

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

Create an alert

  1. In the Google Cloud console, open Monitoring Alerting. Click + CREATE POLICY to open the Create new alerting policy form. Define an alert by adding alert conditions, policy triggers, notification channels, and documentation.

  2. Select ADD CONDITION to open the alert condition form with the Metric tab selected. Fill in the fields to define an alert condition, then click ADD.

  3. After adding the alert condition, complete the alert policy by setting notification channels, policy triggers, documentation, and the alert policy name.

View alerts

When an alert is triggered by a metric threshold condition, Monitoring creates an incident and a corresponding event. You can view incidents from the Monitoring Alerting page in the Google Cloud console. 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.
