Alarms

Based on the configured alarm rules, you can view active alarms of all GaussDB(for MySQL) instances under the current account, including alarms in the Alarm (metric) and Triggered (event) states.

1. In the upper right corner of the Alarms area, click Create Alarm Rule to switch to the Cloud Eye console.
   • By default, the system has a built-in alarm rule, which can be modified, disabled, and deleted. For details, see Modifying an Alarm Rule.
   • Click Create Alarm Rule to create an alarm rule to monitor a metric or event for instances. For details, see Creating an Alarm Rule.
2. In the upper right corner of the Alarms area, select a time window to view alarm details.
   • The time window can be Last 1 hour, Last 6 hours, Last 12 hours, Last day, Last week, or Last month.

   • The Alarm Severity area displays the total number of alarms and the number of alarms of each severity. Alarm severities include Critical, Major, Minor, and Warning.
   • The Top 5 Instances by Total Number of Alarms area displays alarm statistics of the top 5 instances with the largest number of alarms. You can hover over an instance to view the number of alarms of each severity.
   • You can view critical alarm details. For details about critical alarms, see Table 3.

     Table 3 Critical alarm description

     Parameter	Description
     Instance Name	Name of the instance for which the alarm is reported. After the page is refreshed, the latest alarm details will be displayed in real time.
     Status	You can view active alarms of all instances in the current region, including alarms in the Alarm (metric) and Triggered (event) states. Alarm: The metric value reached the alarm threshold, and an alarm has been triggered but not cleared for the resource. Triggered: An event configured in the alarm policy triggered an alarm.
     Alarm Type	Alarm type to which the alarm rule applies. Alarm (metric) Triggered (event)
     Alarm Policy	Policy for triggering an alarm. If you set Alarm Type to Metric, whether to trigger an alarm depends on whether the data in consecutive periods reaches the threshold. For example, Cloud Eye triggers an alarm if the average CPU usage of the monitored object is 80% or more for three consecutive 5-minute periods. For handling suggestions for high CPU usage, see What Should I Do If the CPU Usage of My GaussDB(for MySQL) Instance Is High? If you set Alarm Type to Event, the event that triggers the alarm is an instant operation. For example, if an instance fails to be created, an alarm is triggered. For details about supported events and handling suggestions for exceptions, see Events Supported by Event Monitoring.
     Alarm Rule	Name or ID of the alarm rule
     Last Updated	Latest time when the alarm is triggered
     Operation	Click Metrics. In the displayed dialog box, check the metric monitoring view in the selected time window.

Intelligent Diagnosis

Intelligent Diagnosis checks instance health using operational data analytics and intelligent algorithms and provides diagnosis results and suggestions.

Figure 2 Health diagnosis

Click an abnormal diagnosis item to view the abnormal instances and related metric data.

For example, if the vCPU utilization is high, you can click High vCPU utilization to view the abnormal instances, CPU usage, and CPU usage trend. You can also click Diagnosis Details in the Operation column to view the detailed diagnosis results.

For details about supported diagnosis items and their handling suggestions, see Table 4.
