EC2 Cloudwatch Memory Metrics

-

 

Memory and Disk specific statistics require AWS to monitor at the OS level rather than the host level, so that is why they leave it out by default.

Below are the steps to configure custom metrics:

1) Download and install the Cloudwatch agent on the EC2 instances.

2) Create IAM role to enable the agent to collect metrics from the server end.

3) Attach the IAM role to EC2 instance.

4) Configure Cloudwatch agent to collect RAM(Memory).






Finally, restart the Cloudwatch agent.


Once it is done. Please login to Cloudwatch Console -> All Metrics -> CW Agent -> Host -> IP on the instance.

Create IAM Role:










Attache the role to EC2 instance:




Now under Cloudwatch -> All Metrics

  This is a multi-part series to show how to implement a CI/CD pipeline in AWS. In this post, We will see how to use AWS Code Commit. AWS CodeCommit is a fully managed source control service that allows you to store and manage your code securely in the cloud.  It provides a private Git repository for your code and supports all Git commands and workflows. CodeCommit also integrates with other AWS services like AWS CodePipeline and AWS CodeBuild, allowing you to automate your entire software release process. This can help you streamline your development workflows and improve the overall efficiency of your team. I created a repo from AWS CodeCommit -> Create Repository. And I begin with cloning the repo locally. So that I can make changes and push it. To clone the repo click on "HTTPS" under Clone URL. I make changes to index.html file. Now push it to AWS CodeCommit. Let’s verify the changes in AWS Code commit. Changes are reflected in AWS CodeCommit. We are done with Part ...

Docker - Preventing IP overlapping

  What is IP address overlapping? When the container IP address overlaps with another IP external, then the application running on the container is not accessible from outside due to the IP address overlapping.  NOTE: This IP address overlapping can happen on the bridge interface IP or docker container IP. Let's see how to address this IP overlapping issue on the bridge interface. I already have a running container.  root@demo:~# docker run -d --name web --network mynet1 nginx:alpine 268647e11011d513d2357ce1c81e0f48787038a83d01d028d31a5b29dbdb885b root@demo:~# docker container ls CONTAINER ID   IMAGE          COMMAND                  CREATED         STATUS         PORTS     NAMES 268647e11011   nginx:alpine   "/docker-entrypoint.…"   4 seconds ago   Up 3 seconds   80/tcp  ...
