In this session you will learn how to setup aws application load balancer with auto scaling group.
You will also get knowledge on different types of autoscaling policies. I have demonstrated autoscaling policies in action.
Install stress utility using following command : sudo yum install stress -y
(if you get error, try following command before the stress install command : sudo amazon-linux-extras install epel -y)
Put load on ec2 using following command : sudo stress --cpu 12 --timeout 240s
To set alarm, run following command in aws cloudshell:
aws cloudwatch set-alarm-state --alarm-name CPUUtilzationForTG --state-value ALARM --state-reason "test"

@sajaltimilsina7753 4 месяца назад

I have a question, What was the purpose of, " aws cloudwatch set-alarm-state --alarm-name CPUUtilizationForTG --state-value ALARM --state-reason "test" " this command. What if we do it by increasing the stress?

@itamargardus8156 2 месяца назад

aws cloudwatch set-alarm-state --alarm-name "name of your alarm" --state-value ALARM --state-reason "test

Simply neet explaination ELB & ASG and what application that you used for this slid presentaion?

@kodedge 7 месяцев назад

Thanks for the feedback. I am using keynote for the slides.

@jainkapil6316 5 месяцев назад

Good explanation ❤❤ just one doubt.. If we have 2 ec2 instance in asg and we put load on only one ec2 instance then how cloud watch metric will capture cpu utilization??? Will it be average of both ec2 or it will capture individual load???

@kodedge 5 месяцев назад

Thanks for the feedback. When you have an Auto Scaling group with multiple EC2 instances, the CPU utilization metric reported to CloudWatch will be an average across all instances in the Auto Scaling group. If you put load on only one EC2 instance, CloudWatch will still capture the CPU utilization for that instance, but when you view the metric for the Auto Scaling group as a whole, it will be an average of the CPU utilization across all instances in the group. So, if you put load on only one EC2 instance, that instance's CPU utilization will increase, but the overall average CPU utilization for the Auto Scaling group might not reach the threshold for scaling out unless the other instance(s) also have high CPU utilization or contribute to the average. For detail information please refer this documentation : docs.aws.amazon.com/autoscaling/ec2/userguide/as-scaling-target-tracking.html docs.aws.amazon.com/autoscaling/application/userguide/target-tracking-scaling-policy-overview.html

Hi brother, my ALB DNS is not working, what may be the reasons

@kodedge 7 месяцев назад

Check security group. What is the exact issue you are getting.

@hrentertainment272 7 месяцев назад

@@kodedge getting "502 GATEWAY ERROR"

@kodedge 7 месяцев назад

Hi, Check the security groups of both ALB and AutoScaling group. If proper traffic allowed as shown in the video. Possibly check here as well at : 16:46 in the video. Still if not works try these troubleshooting points: docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-troubleshooting.html#http-502-issues repost.aws/knowledge-center/elb-alb-troubleshoot-502-errors

@rajez.s7157 6 месяцев назад

Isn`t the alarm should be triggered automatically when the desired count is set from 2 to 1? Do we need to manually trigger the alarm referring ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-c4DeyLesQr8.html

@kodedge 6 месяцев назад

We have created alarm for cpu utilisation. When cpu utilisation goes above specified threshold then only alarm will get triggered. Can you elaborate for which alarm you are talking about.

@jainkapil6316 5 месяцев назад

I think desired state works only then asg initially spin up ec2.. Once done... It will work on minsize
