+### Accessing Logs and Debugging on FWoA
+Logs and Debugging are handled by [CloudWatch](https://docs.aws.amazon.com/cloudwatch/index.html). Detailed instructions on customizing CloudWatch to organize troubleshooting can be found [here](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/WhatIsCloudWatch.html).
+
+To access the logs generated by FWoA:
+1. Log on to the AWS Console.
+2. From the list of AWS services, select **CloudWatch**.
+3. From the tab on the left, select **Log Groups**
+4. From the list of log groups, select the Lambda Function or the APIGateway service that you would like to debug.
+  * `/aws/lambda/fhir-service-{STAGE}-fhirServer` contains all the logs from the FWoA API server, including transactions and requests. This will be the log group to check when receiving errors from the FWoA server, in most cases.
+  * `/aws/api-gateway/fhir-service-{STAGE}` contains all the logs related to the setup of the API Gateway for FWoA.
+  * `/aws/lambda/fhir-service-{STAGE}-ddbtoES` contains all the logs from the process of writing DynamoDB resources to ElasticSearch.
+  * `/aws-glue/jobs/output` contains all the logs related to the Bulk Export Glue Job execution.
+  * `/aws/lambda/fhir-service-{STAGE}-getJobStatus` contains all the logs related to querying the status of a Bulk Export job.
+  * `/aws/lambda/fhir-service-{STAGE}-startExportJob` contains all the logs related to starting a Bulk Export job.
+  * `/aws/lambda/fhir-service-{STAGE}-stopExportJob` contains all the logs related to stopping a Bulk Export job.
+  * `/aws/lambda/fhir-service-{STAGE}-updateStatus` contains all the logs related to updating a Bulk Export job.
+  * `/aws/lambda/fhir-service-validator-{STAGE}-validator` contains all the logs pertaining to validation and implementation guides. These are useful in troubleshooting custom resources and implementation guides.
+5. Select a stream to view the output for the function. If applicable, the version of the Lambda function will be prefixed in square brackets (`[]`) to help identify which stream corresponds to which version.
+6. To further refine the output of the function, the events in a stream can be filtered using the options at the top of the list. In addition, you can perform broader searches through the **Log Insights** option on the tab on the left, underneath **Log Groups**.
