# Monitoring in Accelerate
Monitoring

AMS Accelerate monitors supported resources for health, availability, and reliability. For more information about this service offering, see [Monitoring and event management in AMS Accelerate](acc-mon-event-mgmt.md).

AMS Accelerate periodically onboards additional AWS services to baseline monitoring. If you use the Resource Tagger default configuration, these updates are automatically deployed to your accounts, and changes are reflected to the supported resources.

To opt-in to have your Amazon EC2 instances managed by AMS Accelerate, you must apply the following tag via Customization profile in AppConfig; for more information, see [ Step 3: Creating a configuration and a configuration profile](https://docs.aws.amazon.com/appconfig/latest/userguide/appconfig-creating-configuration-and-profile.html). 

Apply the following tag to your resources:


| Key | Value | 
| --- | --- | 
| ams:rt:ams-managed | true | 

For example, you can create a Customized configuration document like this one to apply the tags to all your AMS-supported EC2 resources:

```
{
    "AWS::EC2::Instance": {
        "AllEC2": {
            "Enabled": true,
            "Filter": {
                "Platform": "*"
            },
            "Tags": [
                {
                    "Key": "ams:rt:ams-managed",
                    "Value": "true"
                }
            ]
        }
    }
}
```

**Important**  
Remember to deploy your configuration changes after you have made them. In SSM AppConfig, you must deploy a new version of the configuration after creating it.

Services other than Amazon EC2 will have default baseline monitoring. In order to *opt out* your resources to be monitored by AMS Accelerate, you can use the customization configuration profile to exclude specific resources or AWS services. This allows you to control which resources should have monitoring tags to deploy baseline alarm definitions. See [Resource Tagger use cases in AMS Accelerate](acc-rt-using.md).

**Using Resource Tagger**

The AMS Accelerate Resource Tagger configuration in your account helps ensure that the following tags are deployed automatically, if you apply this one tag (**ams:rt:ams-managed**).

**You will see the following tags being applied to your supported resources for baseline monitoring.**


| Key | Value | Rule | 
| --- | --- | --- | 
| ams:rt:ams-monitoring-policy | ams-monitored | Applies to all EC2 resources supported by AMS | 
| ams:rt:ams-monitoring-policy-platform | ams-monitored-linux | Applies to all Amazon EC2 instances running Linux OS | 
| ams:rt:ams-monitoring-policy-platform | ams-monitored-windows | Applies to all Amazon EC2 instances running Windows OS | 

**For other supported services**

Apply the following tags to your resources, according to the given rules:


| Key | Value | Rule | 
| --- | --- | --- | 
| ams:rt:ams-monitoring-policy | ams-monitored | Applies to all resources supported by AMS Accelerate monitoring. | 
| ams:rt:ams-monitoring-with-kms | ams-monitored-with-kms | OpenSearch Domain with KMS  | 
| ams:rt:ams-monitoring-with-master  | ams-monitored-with-master | OpenSearch Domain with Dedicated Master Node | 

**If you're not using Resource Tagger**

See [Accelerate tags without Resource Tagger](acc-mem-tags-no-rt.md) for help on applying the correct monitoring tags using methods other than using AMS Resource Tagger.

# Configuring tags for EC2 instances in Accelerate
Configuring EC2 instances

AMS Accelerate manages agents on your Amazon EC2 instances, such as the SSM agent and the CloudWatch agent. For more information about this service offering, see [Automated instance configuration in AMS Accelerate](acc-inst-auto-config.md)

To opt-in to have your Amazon EC2 instances managed by AMS Accelerate, you must apply the following tag to your Amazon EC2 instances: 


| Key | Value | 
| --- | --- | 
| ams:rt:ams-managed | true | 

# Managing tags for backups in Accelerate
Backups

AMS Accelerate manages the backing up of supported resources. For more information about this service offering, see [Continuity management in AMS Accelerate](acc-backup.md).

AMS Accelerate backup management uses tags to identify which resources should be automatically backed up (and also provides manual backup capabilities). You can use any tag key:value combination to associate your resources with backup plans. To opt in to automated backups using the **ams-default-backup-plan** AWS Backup plan, you must apply the following tag to your supported resources:


| Key | Value | 
| --- | --- | 
| ams:rt:backup-orchestrator | true | 

**Note**  
During onboarding, AMS Accelerate tags all resources with **ams:rt:backup-orchestrator-onboarding** with value **true** for short interval, short retention snapshots. This is managed by the **ams-onboarding-backup-plan** backup plan. For more information about AMS Accelerate-managed AWS Backup plans, see [Select an AMS backup plan](acc-backup-select-plan.md).
