A cloudwatch alarm template's ARN (Amazon Resource Name) Returns: (String) #comparison_operator ⇒ String The comparison operator used to compare the specified statistic and the threshold. Returns: (String) #created_at ⇒ Time Returns: (Time) #datapoints_to_alarm ⇒ Integer...
We created a CloudWatch alarm using the Level 2 Alarm construct. For the metric, we used the functionErrors metric we created earlier. The threshold is the value against which the statistic emitted by the metric is compared. For example, in our case, the number of error invocations of a la...
CloudWatch Alarm setup Walkthrough Step 1: Define thresholds for alerting Based on the performance that is expected of the application or database, you need to define the thresholds for alerts. Example for IOPS threshold: For example, based on historical trends,...
The tag value is used to specify the threshold. You can alsocreate alarms for custom Amazon CloudWatch metrics. For example, one of the preconfigured, default alarms that are included in thedefault_alarmsdictionary isAutoAlarm-AWS/EC2-CPUUtilization-GreaterThanThreshold-5m-1-Average-Created_by_Clou...
cloudwatch.Metric({ namespace: "AWS/EC2", metricName: "CPUUtilization", dimensions: { InstanceId: instance.instanceId, }, period: cdk.Duration.minutes(1), }); const alarm = new cloudwatch.Alarm(this, "Alarm", { metric, threshold: 5, evaluationPeriods: 1, }); alarm.addAlarmAction(new...
Testing the Alarm Generate an alert by triggering the AWS CloudWatch alarm you just set up, or by clicking Create alert. Check Slack to see that the notification appeared. Bravo! You did it.ImageLabelleris now up and running. Warren Marusiak ...
CloudWatch alarms send notifications or automatically change the resources you are monitoring based on rules that you define. For example, you can monitor the CPU usage and disk reads and writes of your Amazon EC2 instances. Then, use this data to determine whether you should launch additional ...
