AWS Elastic Disaster Recovery Monitoring

AWS Elastic Disaster Recovery - Overview

AWS Elastic Disaster Recovery (DRS) is a cost-effective, reliable disaster recovery solution that minimizes downtime and prevents data loss by continuously replicating source servers using block-level replication to AWS.

ManageEngine Applications Manager'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 regional DRS environment, providing an overview of source server fleet status, replication states, and recovery readiness across AWS Regions.

Applications Manager provides monitoring through three distinct components:

Elastic Disaster Recovery (DRS): Acts as the regional monitor, providing a high-level overview of the source server fleet status, replication states, and recovery readiness across your AWS Regions.
DRS Source Server: Monitors on-premises or cloud-based servers configured for continuous replication to the AWS staging area, offering critical insights into replication health and data synchronization.
DRS Recovery Instance: Monitors the EC2 instances launched during recovery drills or failovers, tracking their performance and status as they take over workloads from the source server.

Monitored parameters

Go to the Monitors Category View by clicking the Monitors tab. Click on the Elastic Disaster Recovery (DRS) instance available under Amazon in the Cloud Apps section. Displayed is the Elastic Disaster Recovery bulk configuration view distributed into three tabs:

Availability tab shows the availability history for the past 24 hours or 30 days.
Performance tab shows health status and events for the past 24 hours or 30 days.
List view tab enables you to perform bulk admin configurations.

By clicking on the respective monitor name from the list, you'll be taken to the Elastic Disaster Recovery dashboard.
