AWS EKS Troubleshooting FAQs

AWS EKS Troubleshooting FAQs

AWS EKS monitor can be configured only if you have already added an Amazon monitor in Applications Manager.
Ensure that you have met the pre-requisites for the Amazon monitor before monitoring Elastic Kubernetes Service in Applications Manager.

How to verify if all the pre-requisites have been met?

  1. Ensure that pre-requisites required to monitor EKS cluster in Applications Manager is met.
  2. Verify if you are able to connect to the EKS cluster with the AWS credentials of the IAM user used in Applications Manager.
    1. For troubleshooting errors while connecting to the EKS cluster, refer the troubleshooting errors section.
    2. For more troubleshooting, refer here.
If the issue still persists, please reach out via mail to appmanager-support@manageengine.com with the below information:
  1. Latest Support Information File (SIF), ensure that 'print all logs' is enabled.
  2. Screenshot of the below mentioned information from prerequisites:
    1. Command: aws --version (To connect to AWS account) --> Sample Output (For windows 10): aws-cli/2.1.29 Python/3.8.8 Windows/10 exe/AMD64 prompt/off
    2. Command: kubectl version --client (To connect to EKS cluster) --> Sample Output: Client Version: v1.19.15-eks-ad4801
    3. IAM username of the user whose credentials used in Applications Manager for EKS cluster monitoring.
    4. EKS config map where the IAM user is added to provide access to the cluster.
    5. Connect to the EKS cluster and run the below commands:
      1. kubectl get nodes
      2. kubectl get pods -A

When the data will be populated for an EKS monitor?

  1. We initiate data collection only when the EKS cluster is in ACTIVE state.

    1. Possible states : CREATING, ACTIVE, DELETING, FAILED, UPDATING

If the cluster is in CREATING/UPDATING state, we will only update the "Cluster Information" group in "Overview" tab.

How to connect to EKS Cluster?

  1. Keep the AWS credentials of IAM user such as Access Key and Secret Access Key used in Applications Manager Amazon monitor ready.
  2. Login using the AWS credentials by executing the below command and entering the relevant details. Make sure to provide the proper region name of the EKS cluster: 
    aws configure
  3. Create the KUBECONFIG file for the required cluster using the below command:  
    aws eks --region {REGION} update-kubeconfig --name {CLUSTER_NAME} --kubeconfig {FILEPATH}

    In the above command,
      1. replace {REGION} with the region of the EKS cluster
      2. replace {CLUSTER_NAME} with the EKS cluster name
      3. replace {FILEPATH} with the path where the KUBECONFIG file should be created. 

        Example        : aws eks --region us-east-1 update-kubeconfig --name EKS-CLUSTER --kubeconfig /home/user/kubeconfig
    1. Note: The current user (running the commands) should have the permission to create and access the KUBECONFIG file.
  4. Execute the below commands to verify if the user is able to access the EKS cluster, replace <FILEPATH> with the path where the KUBECONFIG file should be created:
    1. kubectl get nodes --kubeconfig <FILEPATH>
    2. kubectl get pods -A --kubeconfig <FILEPATH>
  5. If any error occurs, refer the Possible Errors in EKS Monitor and their troubleshooting section and implement necessary steps.

Possible Errors in EKS Monitor and their troubleshooting

Unable to get data from 'eks:DescribeCluster' API (OR)
Access is denied for 'eks:DescribeCluster' API (OR)
Unable to collect data for <SERVICE_NAME>. Access denied for <API_NAME>.
  1. Ensure that you have met the pre-requisites to discover and monitor Elastic Kubernetes Service clusters in Applications Manager.
  2. Login to the AWS console and verify if the IAM user whose credentials used in Applications Manager has permission to the APIs in the pre-requisites.
  3. Check the user name in the EKS config map.
Data collection has stopped as kubectl is not installed. (OR)
Data collection has stopped as aws-cli is not installed.
  1. Ensure that you have followed and done all the pre-requisites.
    1. Steps 2 and 3 are mandatory.
  2. Restart Applications Manager once and check if the environment changes are reflected in Applications Manager.
Data collection has stopped. The user is not authorized to fetch data via kubectl. (OR) Any Unauthorized errors.

  1. Ensure that the user whose credentials were used to add the EKS monitor has root permissions.

  2. To resolve unauthorized error and to add an IAM user to enable access to EKS cluster

    1. Refer here to allow the user to access the cluster.

      1. If the IAM user is the EKS cluster admin, follow the section You're the cluster creator.

      2. If the IAM user is not the EKS cluster admin, follow the section You're not the cluster creator.

Data collection has stopped. Unable to connect to EKS cluster endpoint via kubectl.

  1. If you are using a private EKS endpoint and you encounter this error, refer here to run kubectl commands using private endpoint access.

    1. If you want to add access to kubernetes API server for a specific IP address alone, refer here.

  2. Ensure that the DNS hostnames are enabled in VPC of the EKS Cluster. To enable DNS hostnames and DNS resolution, refer here.

  3. Ensure if the security group's inbound policy is properly configured.

Timeout exceeded when executing kubectl command.

    1. Increase the timeout value. (The default and minimum value for timeout is 30 seconds). To increase the value, go to EKS monitor page, monitor actions -> Edit monitor -> give the appropriate value and update.

    2. Ensure your system has a stable network connectivity.

    3. Run the following kubectl commands to get to know the approximate amount of time it takes to receive a response as these commands take.

      1. kubectl get nodes

      2. kubectl get pods --all-namespaces


If Container Insights data is not being populated:

  1. Verify if you have met all the pre-requisites by verifying using above method.
  2. Ensure whether amazon-cloudwatch pods are in the running state. If they are and if there's still no data in cloudwatch of AWS console, ensure that the CloudWatchAgentServerPolicy has been attached to the node (EC2 instance) in which the amazon-cloudwatch pods are running. For more info, click here.
Make sure container insights data is populated in cloudwatch console.


After clicking a resource, choose 1h and check if data is being collected for the cluster as shown in the below screenshot.


Frequently Asked Questions

How to disable Proxy:

  1. In Applications manager, navigate to Admin > Product settings > Connectivity > Proxy server.
  2. First verify if Proxy server has been configured.
  3. If yes, to exclude kubectl from using proxy, navigate to EKS monitor page > Overview tab > Cluster information and get Cluster Endpoint information. Give the endpoint information in the Do not use proxy for addresses beginning with field without protocol(http/https) 
 
Proxy is only supported from kubectl version 1.19 and above.

How to disable automatic alerts for a specific node condition

Disable the specific condition by navigating to Admin > Performance Polling > Optimize Data Collection > Elastic Kubernetes Service.



If a node is not in the ready state, its health will be automatically affected. If node is in ready state, then we will check the above node conditions and affect the node health based on the configuration.
