What does enable detailed cloud watch metrics do? - amazon-web-services

I am unable to figure out the difference what does enable detailed cloud watch metrics does in aws - api gateway - logs/traces

Detailed CloudWatch metrics for API Gateway will include individual metric data to breakdown each resource/method combination too.
With this enabled you can visualise performance for specific requests such as a /search request latency, or alarm if you return 5XX errors for your /book request.
By default CloudWatch metrics are limited to API and stage.
Enabling this has no effect on logs/traces.

Does Mock integration end point in API Gateway support IntegrationLatency metric?

We have an API Gateway setup with a MockIntegration method. Our deployed stage also has detailed metrics enabled and we can see the following metrics in Cloudwatch:
Count
Latency
5xx errors
4xx errors
However, according to this documentation, API Gateway should also be reporting IntegrationLatency. This metric is missing in Cloudwatch.
Does MockIntegration not support IntegrationLatency? When we eventually move to an actual backend integration, will the metric appear in Cloudwatch?

AWS API Gateway - Monitor specific endpoints

I have created an API Gateway in AWS with two resources (endpoints). Let's say /foo and /bar. Each endpoint has a POST method.
I want to monitor how many times each endpoint got invoked - /foo and /bar in our example. And the metrics to show the 2xx, 4xx, and 5xx responses.
I know API Gateway got a generic "API Calls" metric that shows the total invocations of the API. But how do I monitor how many times each endpoint got called?
You can filter API Gateway metrics for the API method with the specified API name, stage, resource, and method.
API Gateway will not send these metrics unless you have explicitly enabled detailed CloudWatch metrics. You can do this in the console by selecting Enable Detailed CloudWatch Metrics under a stage Logs/Tracing tab. Alternatively, you can call the update-stage AWS CLI command to update the metricsEnabled property to true.

what is the difference among amazon inspector vs trusted advisor vs cloudwatch vs Personal Health Dashboard vs AWS cloudtrail?

Hi dear StackOverflow community,
These below amazon concepts are confusing to me, I do not get to establish the key difference among them at once:
Amazon inspector vs trusted advisor vs cloudwatch vs Personal Health Dashboard vs AWS cloud trail.
Could you help me to get clarity in the key difference among them?
Thank you very much in advance
Trusted Advisor
Trusted Advisor offers recommendations to lower cost and improve security, performance and fault tolerance. Some are provided for free, while all of the recommendations are only available to subscribers to AWS Support.
Personal Health Dashboard
AWS Personal Health Dashboard shows issues and outages that might affect your usage of AWS services.
Amazon CloudWatch
Amazon CloudWatch stores metrics and allows Alarms to be configured based on those metrics. Many AWS services send metrics to CloudWatch, such as Amazon EC2 providing CPU metrics and Amazon S3 providing storage metrics. It also has CloudWatch Logs that can store log files and respond to log messages, and CloudWatch Events that can trigger actions in response to certain events).
AWS CloudTrail
AWS CloudTrail is an audit trail of API calls made to AWS. It tracks details of all requests, such as the user, source IP, timestamp, request parameters and the success of the API call. Just like a security company keeps track of every time you use a swipe-card, CloudTrail keep track of every time a request is made to an AWS service.
Amazon Inspector
Amazon Inspector runs on Amazon EC2 instances and scans the computer for known vulnerabilities in the operating system and applications.

What to prefer AWS XRAY or CloudTrail for analysing user request travelling through Amazon API Gateway

I am preparing for AWS exam and I found some documentation about AWS CloudTrail and AWS X-RAY where it creates confusion on their usage requirement.
I have came across following question where requirement was to trace and analyse the user request as it travels through Amazon API Gateway APIs to underlying services.
As per my understanding, we can use CludTrail to trace and analyse the user request. But the correct answer was AWS XRAY.
The documents which have referred mentions that, we can use AWS CloudTrail logs for tracing,Security Analysis, Resource Change Tracking and Compliance/Auditing. On the other hand, we can use AWS X-RAY to analyse and debug applications running on distributed micro service architecture.
XRAY and CloudTrail usage both have the term Analyse and trace. So it is quite confusing to which service should we choose under such requirement to trace and analyse the user request
X-Ray is more detailed in the information it provides for the request's flow and state. It scans the request all the way through its lifetime from when it is received in the api gateway to whatever services are called and executed after that. So I imagine that is why it is the preferred option.

Retrieve Amazon CloudWatch Alarms using REST API

I'm trying to retrieve all open Alarms (alerts) from Amazon Monitoring tool: Cloudwatch, using REST API GET.
And while Azure Monitor has a very clear documentation that contains the Alerts Management endpoint:
https://management.azure.com/subscriptions/{SubscriptionID}/providers/Microsoft.AlertsManagement/alerts?includeContext=True&api-version=2018-05-05
On Amazon side, on the other hand. i got confused.
After reading Amazon Cloudwatch documentation.
I understood that i need to pull the data from Cloudwatch Alarms, and not from Cloudwatch Log or Cloudwatch Events.
But i didn't find a corresponding endpoint to use in order to retrieve all the open Alarms (alerts) in Cloudwatch using REST API Get, from the available AWS Service Points:
https://docs.aws.amazon.com/general/latest/gr/rande.html
Can someone shed some light on this please?
https://github.com/awsdocs/aws-doc-sdk-examples/blob/master/ruby/example_code/cloudwatch/cw-ruby-example-show-alarms.rb
here is a ruby example of describe alarms end point. You should be able to do the same using other programming languages as well.
