- Detailed explanations for AWS CloudWatch and Visual Explanations. Fully Simplified.
When you think of CLOUD WATCH, remember something very clearly,
It is a service that you could ignore and it won't make an impact on the overall performance of your actual application.
But if not used properly and effectively, would surely result in issues that you might have a hard time debugging and resolving.
Along with providing a feature set where you can send logs to this service using log streams and use its dashboards to create reports on the performance of your service,
It can also help you analyze the datapoint to understand where your application could actually break.
So, as it is rightly mentioned here, CloudWatch collects monitoring and operational data in the form of logs, metrics, and events, and visualizes it using automated dashboards so you can get a unified view of your AWS resources, applications, and services that run in AWS and on-premises.

These videos are helping us much. We really appreciate your hard work and dedication, Thanks a lot!
Awesome content. Better than many paid content. Highly appreciate your effort.
This video is far better than the course that I purchased on udemy
Thank u ashwath for supporting. Please do share with your friends it really helps
This is a top-notch channel for AWS cloud learning - period. Great explanation, High quality content and tackles real-time scenarios. This channel deserves more subscribers.
Thanks for the support. Please spread the word. Helps a lot
I'm taken by this. I had the privilege of reading something similar, and I was truly taken by it. "Mastering AWS: A Software Engineers Guide" by Nathan Vale
It was worth it for sure. I am preping for AWS CA exam. Hope this should help me in passing exam and also implement some solutions
This is really good. He takes time to give details and visualization for good understanding. Great jobs. Thanks.
This is really high-quality stuff that I have loved watching and learning. Thanks once again for this wonderful animated video.
Thank you for the detailed video on cloudwatch. some times even the most basic things will make sense and click to us during architecture designing if we go through it clearly and concisely. Kudos!
You are the best tutor😊
Thanks a lot Mahesh 🙏
This really a very informative course. Your course is helping me understand the detailed concepts of cloud. Thanks for all the efforts.
thanks bhavana
all the best
Hi, very nicely explained, animations are the key which makes to understand easily, many thanks for sharing.
Thanks rekha
Thank you so much for all the efforts you've put in to create these very informative videos
thanks anju
Excellent Session!
Amazing video not this , all your video are Great to watch , Many Thanks
Thanks for the video, 😊
A request, please start your videos with some questions that are asked in AWS certification.
Sure 😃 thanks for the feedback
Brother really great thanks please do more videos on premises
Great video
Really good one... Visually so beautiful one👍
very well explained, thank you sir .
Thanks 😊
Very well explained! But if you are using Kubernetes, the setup will change vastly!
Thank you, best explanation of CloudWatch on RUclips!
Can you please explain the difference between using autoscaling groups vs using CloudWatch Events to scale EC2 instances? Are there 2 different ways (through ASG and CloudWatch) to implement autoscaling?
Sure !!
Really good content with unique methodology
Hi, The explanation of concepts is exceptional and very helpful but it would be great if you can provide a hands-on lab on AWS console level for the topic thought in the video. Thank you😊
Thanks a lot for the feedback.
My man! Thank you!
Please make video on Prometheus and Grafana.
Your content and videos are amazing. If you don't mind can you tell which software you use to create these fascinating videos?
Thanks bro.. it's just PowerPoint and it's Animation
Great videos man...Thank you for taking time to make these.
Do you have any video or guidance to understand the existing architecture. For an example, how to know what does the EC2 instance do and how are they connected
Hi, please refer the link for the playlist of the course. I have a lot of videos on EC2.
I hope that would help
great Video ! thank you
Awesome content. I subscribed your channel.
condition: if i have launched 2 ec2 with the help of autoscaling group. and now i want autoscaling group to launch one more ec2 if there is more than 50% cpu utilization on only one ec2. and also to set alarm for cpu utilization so what changes do i have to make in alarm so that if i only increase cpu utilization on one ec2 out of 2 then 1 more instance will be launched?
To achieve this, you'll need to create a CloudWatch alarm that monitors CPU utilization and then configure the Auto Scaling group to respond to that alarm. Here's a step-by-step guide:
Create a CloudWatch Alarm:
a. Sign in to the AWS Management Console, and open the CloudWatch console at console.aws.amazon.com/cloudwatch/.
b. In the navigation pane, click on "Alarms," then "Create alarm."
c. Click on "Select metric," then choose the "EC2" namespace and select the "Per-Instance Metrics" tab.
d. Select the "CPUUtilization" metric, and then click "Select metric."
e. Configure the alarm settings:
Name: Provide a unique name for the alarm.
Description (optional): A brief description of the alarm.
"Whenever" condition: Select "CPUUtilization" and set the condition to "GreaterThanOrEqualToThreshold" with a value of 50.
"For at least" field: Set the consecutive periods and duration for which the alarm should be triggered (e.g., 1 period of 1 minute).
"Actions" section: Under "Auto Scaling action", select "Add action" and choose "Scale out" and then select the relevant Auto Scaling group.
f. Click "Create Alarm."
Configure the Auto Scaling group:
a. Open the Amazon EC2 console at console.aws.amazon.com/ec2/.
b. In the navigation pane, click on "Auto Scaling groups."
c. Select the Auto Scaling group you want to modify, and click on the "Scaling policies" tab.
d. Click on "Create scaling policy" and select "Step scaling policy" or "Target tracking policy" based on your preference.
e. Configure the policy settings as needed, making sure to associate the CloudWatch alarm you created in step 1.
Now, when the CloudWatch alarm is triggered (CPU utilization is above 50% on any single instance), the Auto Scaling group will launch an additional EC2 instance. Note that this setup may not be ideal for all situations, as it can lead to unnecessary scaling if only one instance is experiencing high CPU utilization while the other instance(s) remain idle. Consider your specific use case and load distribution requirements when implementing this solution.
@@Pythoholic did this already but didn't work..i had to increased cpu utilization on both ec2..but the thing is i want to increase utilization of only one ec2 and want to see if auto scaling group will launch 3rd ec2 or not?
The issue here is that by default, CloudWatch alarms for EC2 instances are aggregated across instances within an Auto Scaling group. When you create an alarm based on the "CPUUtilization" metric, it's actually monitoring the average CPU utilization across all instances in the group.
To achieve the desired behavior of launching a new instance when any single instance has a CPU utilization greater than 50%, you can use a custom CloudWatch metric that records the maximum CPU utilization of any instance in the Auto Scaling group.
@@Pythoholic okay i"ll try and will tell u..thanks for the guidance bdw
bro plz dont think dat m criticizing u m ur wellwisher ur voice d way u r teaching all things r gud but i think dat u have to improve this topic
thanks bro i am all in for feedback
Hello Quick: Scenario CloudWatch alarm/metric pointing to a Stream log file pattern: "ERROR" period: 30 minutes. Alarm got into state: In Alarm, and sends a event to SNS to received an email from the alarm state, When consecutive state of alarm I am just getting one single alarm. Is there a way to configure alarm to get 2 or 3 different emails if Alarm state continue with the same In-Alarm state as many as consecutive iteration?
Amazon CloudWatch Alarms are designed to send notifications when they change state. By default, they do not continue to send notifications for every evaluation period that the alarm remains in the same state. If an alarm stays in the `ALARM` state over multiple periods, it does not send multiple notifications.
However, there are a few workarounds to achieve what you want:
1. **Use AWS Step Functions or AWS Lambda:** You can create a Step Function or Lambda function that triggers on the CloudWatch alarm's SNS message. This function could then be set to send additional emails at your desired interval until the alarm state is cleared. Note, this requires additional setup and management.
2. **Create more alarms with different thresholds or periods:** You could create additional alarms with slightly different thresholds or periods. This isn't an ideal solution because it might cause some false positives, but it would give you multiple notifications.
3. **Metric Math Alarm:** If your use case allows, you can use metric math expressions to create an alarm. For example, you can create an alarm that triggers when the sum of errors over the last three periods exceeds a certain threshold.
4. **Using third-party services:** You could consider using a third-party service that offers more advanced alerting options than CloudWatch. These services often have features to customize alerts and notifications in a more granular way.
Remember, it's important to manage and keep track of these notifications to avoid noise and ensure that the important alerts are not missed.
Hi .. Can you do EKS and ECR videos
