How can I troubleshoot and resolve the issue of falling RDS Instances continuously?

222    Asked by CaroleThom in AWS , Asked on May 6, 2024

 I am a system administrator and I am responsible for managing a cloud infrastructure that includes an Amazon relational database service instead of critical business data. One day my team noticed that the automated backup for the RDS Instance has been failing consistently for the past week. How can I approach troubleshooting this particular issue and ensure that backups are running smoothly to maintain data integrity and disaster recovery readiness? 

Answered by Carole Thom

In the context of AWS, here are the steps given for how you can troubleshoot and resolve the issue of failed automated backup for an Amazon RDS instance:-

Checking RDS backup status

You can use the AWS management console to check the status of automated backup for the RDS Instance. You can look for the error message or status code which indicates why the backups are falling.

Review cloud watch logs

You can access cloudwatch logs to review logs to the RDS Instance and automated backup. You can there look for any error message that is causing backup failure.

Verify IAM permission

You should ensure that the IAM role or user associated with the RDS Instance has the necessary permission to perform an automated backup.

Checking resources limit

You can review the resource limit for the RDS Instance, including storage space and CPU utilization.

Testing manual backup

You can also initiate w backup of the RDS instance by using the AWS management console or AWS CLI to see if it is completed successfully. This would help in isolation whether the issues are with automated backup or the RDS instance itself.

Here is the coding structure given for the above steps:-

Import com.amazonaws.services.rds.AmazonRDS;
Import com.amazonaws.services.rds.AmazonRDSClientBuilder;
Import com.amazonaws.services.rds.model.DescribeDBInstancesRequest;
Import com.amazonaws.services.rds.model.DescribeDBInstancesResult;
Import com.amazonaws.services.rds.model.DBInstance;
Import com.amazonaws.services.logs.AWSLogs;
Import com.amazonaws.services.logs.AWSLogsClientBuilder;
Import com.amazonaws.services.logs.model.GetLogEventsRequest;
Import com.amazonaws.services.logs.model.GetLogEventsResult;
Public class RDSTroubleshooting {
    Public static void main(String[] args) {
        AmazonRDS rdsClient = AmazonRDSClientBuilder.defaultClient();
        AWSLogs logsClient = AWSLogsClientBuilder.defaultClient();
        String instanceIdentifier = “your-db-instance-identifier”;
        String logGroupName = “/aws/rds/instance/” + instanceIdentifier + “/logGroup”;
        String logStreamName = “your-log-stream-name”;
        // Step 1: Checking RDS Backup Status
        DescribeDBInstancesRequest request = new DescribeDBInstancesRequest()
            .withDBInstanceIdentifier(instanceIdentifier);
        DescribeDBInstancesResult result = rdsClient.describeDBInstances(request);
        For (DBInstance dbInstance : result.getDBInstances()) {
            System.out.println(“DB Instance ID: “ + dbInstance.getDBInstanceIdentifier());
            System.out.println(“Backup Status: “ + dbInstance.getBackupRetentionPeriod());
        }
        // Step 2: Review CloudWatch Logs
        GetLogEventsRequest logRequest = new GetLogEventsRequest()
            .withLogGroupName(logGroupName)
            .withLogStreamName(logStreamName);
        GetLogEventsResult logResult = logsClient.getLogEvents(logRequest);
        logResult.getEvents().forEach(event -> System.out.println(event.getMessage()));
        // Additional steps:
        // - Verify IAM permissions
        // - Checking resources limit
        // - Testing manual backup
        // Implement these steps as needed.
    }
}
