Using Event Monitoring

Event monitoring provides reporting, query, and alarm functions for event data. It allows you to collect and report various important service events and cloud resource operational events to Cloud Eye and receive alarm notifications when exceptions occur.

Events are key operations on cloud service resources that are stored and monitored by Cloud Eye. You can view events to see operations performed by specific users on specific resources, such as delete ECS or reboot ECS.

Event monitoring is enabled by default. You can view monitoring details about system events and custom events. For details about the supported system events, see Events Supported by Event Monitoring.

Event monitoring provides an API for reporting custom events, which helps you collect and report abnormal events or important change events generated by services to Cloud Eye. For details about how to report custom events, see Reporting Events.

The differences between custom event monitoring and custom monitoring are as follows:

  • Custom event monitoring is used to report and query monitoring data for non-consecutive events, and generate alarms in these scenarios.
  • Custom monitoring is used to report and query periodically and continuously collected monitoring data, and generate alarms in these scenarios.

Creating an Alarm Rule

  1. Log in to the management console.
  2. Under Management & Deployment, select Cloud Eye.
  3. In the navigation pane on the left, choose Event Monitoring.
  4. In the event list, locate the target event and click Create Alarm Rule in the Operation column.
  5. Configure the alarm rule name, alarm policy, and alarm notification as prompted.

    After the alarm rule is created, if the metric data reaches the alarm policy, Cloud Eye immediately informs you, through SMN, that an exception has occurred.
