Now that we have policies installed, and traffic being generated in the cluster, we can look at the CloudWatch integration that TSCE provides.
We’re assuming that you have run through both the Calico section of this tutorial and the first part of the TSCE section. If you skipped the Calico section, please go back and run through that as well, as we are relying on the synthetic applications used in the Calico examples to generate flowlogs in CloudWatch.
You need to get the clusterGUID of the EKS cluster. To do that, run the following command:
kubectl get clusterinformation default -o yaml | grep GUID
In the cloud9 shell, go to the AWS dashboard, and select the Cloudwatch service.
Go to the metrics section, and select all of the metrics being reported by your clusterID. See the screenshot below
Just as in the screenshot, you should now see CloudWatch graphing various statistics such as denied packets, unhealthy nodes, etc.
Similarly, you can see the actual flow logs by switching from the Metrics to the Logs view, as shown below
