方法详细资料

expressionList

public PutResourceMetricRuleRequest.CompositeExpression.Builder expressionList(List<PutResourceMetricRuleRequest.ExpressionList> expressionList)

The trigger conditions that are created in standard mode.

expressionListJoin

public PutResourceMetricRuleRequest.CompositeExpression.Builder expressionListJoin(String expressionListJoin)

The relationship between the trigger conditions for multiple metrics. Valid value:

• &&: An alert is triggered only if all metrics meet the trigger conditions. An alert is triggered only if the results of all expressions specified in the ExpressionList parameter are true.
• ||: An alert is triggered if one of the metrics meets the trigger conditions.

example:

||

expressionRaw

public PutResourceMetricRuleRequest.CompositeExpression.Builder expressionRaw(String expressionRaw)

The trigger conditions that are created by using expressions. You can use expressions to create trigger conditions in the following scenarios:

• Set an alert blacklist for specific resources. For example, if you specify $instanceId != \"i-io8kfvcpp7x5****\" ``&&`` $Average > 50, no alert is triggered when the average metric value of the i-io8kfvcpp7x5**** instance exceeds 50.
• Set a special alert threshold for a specified instance in the rule. For example, if you specify $Average > ($instanceId == \"i-io8kfvcpp7x5****\"? 80: 50), an alert is triggered when the average metric value of the i-io8kfvcpp7x5**** instance exceeds 80 or the average metric value of other instances exceeds 50.
• Limit the number of instances whose metric values exceed the threshold. For example, if you specify count($Average > 20) > 3, an alert is triggered only when the average metric value of more than three instances exceeds 20.

example:

$Average > ($instanceId == "i-io8kfvcpp7x5****"? 80: 50)

level

public PutResourceMetricRuleRequest.CompositeExpression.Builder level(String level)

The alert level. Valid values:

• Critical
• Warn
• Info

example:

Critical

times

public PutResourceMetricRuleRequest.CompositeExpression.Builder times(Integer times)

The number of consecutive triggers. If the number of times that the metric values meet the trigger conditions reaches the value of this parameter, CloudMonitor sends alert notifications.

example:

3
