What is CloudWatch? And how do we get started?

CloudWatch is a very powerful tool for monitoring and troubleshooting in AWS. In this lesson, we will discuss CloudWatch basics and move on to CloudWatch alarms, the actions we can perform with them, and how to configure them.

CloudWatch Essentials
11:23

CloudWatch Events are a way to automatically take action with our AWS resources based on certain event triggers or schedules. In this lesson, we will discuss what CloudWatch Events are, how to configure them, and common uses for them.


CloudWatch Events
07:15

CloudWatch Logs are an excellent way to provide alarming, dashboards, and reporting from other sources in AWS like CloudTrail. In this lesson, we will discuss the different components of CloudWatch Logs and how we can use them to set custom alarms in our environment.


CloudWatch Logs
08:43

Status checks are made up of Instance Status Checks and System Status Checks. Errors in these indicate different issues, and should, therefore, be recovered differently. This lesson discusses AWS System and Instance Status Checks and how to recover from an error in these checks.


EC2 Status Checks
02:43

There is a large variety when it comes time for us to select an EC2 instance type. Some families are more suited for particular tasks. We, as SysOPs Administrators, should know what options are available to us. There is also a large difference in most families between the smallest and largest instance size that can affect performance. This lesson discusses the virtualization types, instance types, and instance sizes we can configure for our EC2 instances.


EC2 Types and Performance
07:54

The EC2 service had the most metrics of any service. There are many we can use without additional charges. There are, however, a few metrics that are not reported by default. These can be called custom metrics and involve installing an agent on the EC2 instance itself. This lesson discusses basic EC2 metrics for CloudWatch and how we can get custom, OS-level metrics sent to CloudWatch as well.



Here are the commands used in this video:




######## Install CloudWatch Agent ############

wget https://s3.amazonaws.com/amazoncloudwatch-agent/linux/amd64/latest/AmazonCloudWatchAgent.zip

unzip AmazonCloudWatchAgent.zip

sudo ./install.sh 

######## Configure CloudWatch Agent ############

/opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-config-wizard

EC2 Metrics and Custom Metrics
13:32

CloudWatch is not always the best monitoring solution. Applications may sometimes need their own custom solution. Whether for a backup to CloudWatch or for specialized applications, setting up an instance to ping the environment is an important skill. This lesson discusses how to set up an instance and get it monitoring.


EC2 Dedicating an Instance for Monitoring
06:35

It is important to know the basics of EBS volumes to be able to make informed decisions in our environment. This lesson discusses some of the facts that are necessary to know for administering EBS and for the exam.

EBS Essentials
03:54

Performance of your EBS volumes should be a priority in your environment. Storage size, bursting, throughput, and IOPS can all cause issues. Also, if we haven't "tuned" our EBS usage carefully, we could be spending more than we really need to. This lesson discusses the performance options a user has when provisioning EBS volumes.


EBS Performance
13:02

The metrics we need to monitor are varied and greatly depend on the volume type. This lesson discusses EBS metrics in CloudWatch and how we can use them to make performance decisions with our volumes.

Scenarios that show the benefits of using them are also provided.


EC2 Reserve Instances
05:31

Load balancers are responsible for serving traffic to multiple instances in an application. In addition, they can also prevent poor application performance by evaluating the health of the instances it serves. Traffic can then be directed to only those instances that are "healthy." This lesson discusses how Elastic Load Balancers can assist in scalable, highly available applications.



ELB: High Availability
06:38

Messaging services can be used to decouple applications. Because these services are scalable and highly available, they provide applications with the ability to grow automatically. This lesson discusses how we can use messaging services to make applications scalable.

07:58
+ Ensure level of fault tolerance based on business needs
3 lectures 23:44

In the event of an availability zone failure, instances will still need access to the internet for updates. If multiple NAT gateways are deployed, we can allow for this. Bastion hosts also need to be available when an AZ fails. This lesson discusses how to make Bastion Hosts and NAT Gateways fault tolerant.


EC2: NAT Gateway and Bastion Hosts
13:36

Multi-AZ is a fault tolerant feature in Relational Database Service. It prevents an availability zone failure from removing database access from an application. This lesson discusses RDS Multi-AZ deployments and how they handle fault tolerance. There is also a simulated failover executed.
