AWS Elastic Disaster Recovery integration
AWS Elastic Disaster Recovery (DRS) is a cost-effective, reliable disaster recovery solution that minimizes downtime, prevents data loss, and maintains up-to-date backups of your servers.
Overview
Site24x7's integration with AWS DRS offers a streamlined way to monitor and manage your disaster recovery operations. This integration provides real-time monitoring of your AWS DRS environment, tracking the health and performance of your disaster recovery setup.
It also provides you with two child monitors in addition to the Elastic Disaster Recovery monitor:
- DRS Source Server: Monitors all the source servers and provides critical insights into supported Amazon CloudWatch metrics.
- DRS Recovery Instance: Monitors the recovery instances of a particular source server and the reversed replication.
Use case
Consider that you have an Elastic Disaster Recovery monitor, which has multiple source servers as well as recovery instances of the source servers, that you want to retrieve in the event of disaster recovery.
In this scenario, if your DRS environment is integrated with Site24x7, you can gain critical insights into the DRS summary and monitor the source servers and recovery instances for each region. This integration also allows you to monitor the CloudWatch metrics so that you can take appropriate actions in time to minimize the downtime and data loss of on-premises and cloud applications.
Benefits of Site24x7's DRS integration
Integrate your DRS environment with Site24x7 to:
- Obtain a comprehensive view of your disaster recovery environment.
- Individually monitor your source servers and recovery instances for each region.
- Set thresholds for metrics and receive alerts for threshold breaches.
- Manage, optimize, and ensure the reliability of your disaster recovery processes.
Setup and configuration
- Log in to your Site24x7 account.
- Go to Cloud > AWS > Integrate AWS Account and create a cross-account IAM role to enable Site24x7 to access your AWS resources.
- On the Integrate AWS Account page, select Elastic Disaster Recovery from the Services to be discovered list.
Permissions
Ensure that Site24x7 receives the following permissions to monitor DRS:
- "drs:DescribeSourceServers"
- "drs:ListStagingAccounts"
- "drs:ListTagsForResource"
- "drs:GetReplicationConfiguration"
- "drs:GetLaunchConfiguration"
- "drs:DescribeRecoveryInstances"
Polling Frequency
Site24x7 queries AWS service-level APIs according to the set polling frequency (from once a minute to once a day) to collect metrics from an Elastic Disaster Recovery monitor.

Threshold configuration
To configure thresholds for an Elastic Disaster Recovery monitor:
- Log in to your Site24x7 account and navigate to Admin > Configuration Profiles > Threshold and Availability.
- Click Add Threshold Profile.
- Select the applicable monitor type from the Monitor Type drop-down menu and provide an appropriate name in the Display Name field. The applicable monitor types are Elastic Disaster Recovery, DRS Source Server, and DRS Recovery Instance.
- The supported metrics are displayed in the Threshold Configuration section. You can set threshold values for all the metrics mentioned above.
- Click Save.
You can manage all the alerts to ensure that the notifications are sent through the parent monitor with the status propagation feature.
Licensing
- Elastic Disaster Recovery: Each Elastic Disaster Recovery monitor utilizes one basic monitor license.
- DRS Source Server: Each DRS Source Server monitor utilizes one basic monitor license.
- DRS Recovery Instance: Each DRS Recovery Instance monitor utilizes one basic monitor license.
