Automatic alert creation

Create and customize automatic alerts

DuploCloud allows you to set up automatic alerts for resources in a tenant. These alerts help monitor system health and performance by applying standard thresholds (e.g., CPU usage) to supported resource types like EC2, RDS, and others.

Alerts can be customized using exclusion rules, giving you control over which resources are included in auto alerting.

Creating an Automatic Alert

1. Select the Alerting tab

2. Click Enable Alerting to generate a default alert template. This template includes predefined rules for common AWS namespaces and metrics.

3. Review the generated rules and update the thresholds or evaluation periods as needed to match your alerting requirements.

4. Click Update to save the alert configuration.

   

Enabling Alerting

Enable automatic alerting for your Tenant.

1. In the DuploCloud Portal, navigate to Administrator → Tenants.

2. Select your Tenant from the NAME column.

3. Select the Alerting tab.

4. Click Click Here or Enable Alerting. Once enabled, DuploCloud’s predefined out-of-the-box alert rules are enabled for the Tenant.

Customizing Alerts by Excluding Resources

Automatic alerts in DuploCloud apply to all resources of a given type, like all EC2 instances or all RDS databases. Sometimes, you may want to exclude specific resources from these alerts. This is done by adding an ExcludeDimensions rule to the alert configuration.

To exclude a resource from an alert:

1. Go to Administrator → Tenants in the DuploCloud portal.

2. Select the name of the Tenant from the NAME column.

3. In the Alerting tab, check whether alerting has already been enabled:

   • If not, click Enable Alerting. A default alert template will be generated with predefined rules for supported AWS namespaces and metrics.

   • If alerting is already enabled, click the edit icon in the Alert Template JSON section to modify the existing rules.

4. In the alert template, locate the rule where you want to add the excludedDimensions block. You can identify rules by their metricName or namespace.

5. Add an ExcludeDimensions block with the resource’s:

   • Name: The type of ID used for the resource (like InstanceId for EC2), and

   • Value: The exact resource ID or name you want to exclude.

6. Click Update to save the changes.

Example

The following configuration excludes the EC2 instance with ID i-0a1b2c3d4e5f6g7h8 from CPUUtilization alerts:

{
  "HOSTS": [
    {
      "ExcludeDimensions": [
        {
          "Name": "InstanceId",
          "Value": "i-0a1b2c3d4e5f6g7h8"
        }
      ],
      "Severity": 0,
      "Cloud": 0,
      "ComparisonOperator": "GreaterThanOrEqualToThreshold",
      "Dimensions": [],
      "EvaluationPeriods": 1,
      "MetricName": "CPUUtilization",
      "Namespace": "AWS/EC2",
      "Period": 300,
      "StateTransitionedTimestamp": "0001-01-01T00:00:00",
      "Statistic": "Average",
      "Threshold": 70
    }
  ]
}

Common Resource Types and IDs

Resource Type	Name	Example Value
EC2 Instance	InstanceId	i-0123456789abcdef0
RDS Database	DBInstanceIdentifier	my-database-1
ECS Cluster	ClusterName	my-ecs-cluster
Lambda Function	FunctionName	my-function
SQS Queue	QueueName	my-queue
Redis Cache	CacheClusterId	my-redis-cache
Load Balancer (ALB/NLB)	TargetGroup	targetgroup/my-tg/abcdef123

Resource Exclusion Tips:

• To exclude the same resource from multiple alerts, add the exclusion to each alert rule individually.

• If a Name value is invalid or unsupported, it will be ignored and the resource will not be excluded.

• The Dimensions field is not currently used for including resources. It only applies to exclusions.

• Not sure which dimension name to use? Refer to the AWS CloudWatch documentation for your specific resource type.
