Configuring an Alarm Threshold

Scenario

You can configure an alarm threshold to learn the metric health status. After Send Alarm is selected, the system sends an alarm message when the monitored data reaches the alarm threshold. You can view the alarm information in Alarms.

Procedure

1. On MRS Manager, click System.
2. In Configuration, click Configure Alarm Threshold under Monitoring and Alarm, select monitoring metrics as planned, and set their baselines.
3. Click a metric, for example, CPU Usage, and click Create Rule.
4. Set the monitoring metric rule parameters on the displayed configuration page.

   Table 1 Monitoring metric rule parameters

   Parameter	Description	Value
   Rule Name	Specifies the rule name.	CPU_MAX (example)
   Reference Date	Specifies the date on which the reference indicator history is generated.	2014/11/06 (example)
   Threshold Type	Specifies the maximum or minimum value of a metric. If this parameter is set to Max. Value, the system generates an alarm when the actual value of the metric is greater than the threshold. If this parameter is set to Min. Value, the system generates an alarm when the actual value of the metric is smaller than the threshold.	Max. value Min. value
   Alarm Severity	Alarm Severity	Critical Major Minor Warning
   Time Range	Specifies the period in which the rule takes effect.	From 00:00 to 23:59 (example)
   Threshold	Specifies the threshold of the rule monitoring metrics.	80 (example)
   Date	Specifies the type of date when the rule takes effect.	Workday Weekend Other
   Add Date	This parameter is valid only when Date is set to Other. You can select multiple dates.	11/30 (example)

5. Click OK. A message is displayed in the upper right corner of the page, indicating that the template is saved successfully.

   Send alarm is selected by default. MRS Manager checks whether the value of each monitored metric reaches the threshold. If the number of consecutive check times is equal to the value of Trigger Count, and the threshold is not reached in these checks, the system sends an alarm. The value can be customized. Check Period (s) indicates the interval at which MRS Manager checks monitoring metrics.

6. Locate the row that contains the newly added rule, and click Apply in the Operation column. A message is displayed in the upper right corner, indicating that the rule xx is successfully added. Click Cancel in the Operation column. A message is displayed in the upper right corner, indicating that the rule xx is successfully canceled.
