By monitoring cluster running metrics, you can identify the time when the database cluster is abnormal and analyze potential activity problems based on the database logs, improving database performance. This section describes the metrics that can be monitored by Cloud Eye as well as their namespaces and dimensions. You can use the management console or APIs provided by Cloud Eye to query the monitoring metrics and alarms generated by GaussDB(DWS). For details, see the <em id="EN-US_TOPIC_0000001924569356__i26421014121515">User Guide</em> and <em id="EN-US_TOPIC_0000001924569356__i5642914101515">API Reference</em> of Cloud Eye.</p>
