We are in the process of migrating from activeMQ to amazonMQ on AWS. ActiveMQ and AmazonMQ internally uses kahaDB as there data store.
Earlier we were able to see kahaDB logs files while using activeMQ on data center is there a similar way of seeing the kahadb logs file on AWS while using amazonMQ?
Tried enabling cloudwatch logs but it contains general and audit logs of amazonMQ.
I checked with AWS technical team, they don't allow to access the kahaDB logs.

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.
Suppose multiple aws services are running (like EC2,S3) and If someone changes the configuration of these services , I want to know immediately and want to pull the updated configuration. So how can i listen to these services to pull configuration immediately . I went through couple of options like aws SNS and all. But i don't want to implement this using any aws services for this.
I am using spring boot application. Any help is appreciated , Thanks in advance.
The two services you should be interested in are:
AWS CloudTrail:
AWS CloudTrail is an AWS service that helps you enable governance, compliance, and operational and risk auditing of your AWS account. Actions taken by a user, role, or an AWS service are recorded as events in CloudTrail. Events include actions taken in the AWS Management Console, AWS Command Line Interface, and AWS SDKs and APIs.
AWS Config:
AWS Config provides a detailed view of the configuration of AWS resources in your AWS account. This includes how the resources are related to one another and how they were configured in the past so that you can see how the configurations and relationships change over time.
You can also configure Amazon CloudWatch Events rules that trigger when a particular API call is made (eg when a user changes some configuration). This could trigger a notification, a Lambda function, etc.

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.
I am planning to export logging from MuleSoft CloudHub to AWS CloudWatch.
I saw there is one AWS CloudWatch Connector in GitHub:
https://github.com/mulesoft-labs/mule-amazon-cloudwatch-connector/tree/master/mule-cloudwatch-connector
Is there any examples on how to implement this?
And which AWS CloudWatch features is supported in this connector?
I found other export logs method with examples, but not for AWS CloudWatch:
https://help.mulesoft.com/s/question/0D52T00004mXUALSA4/export-log-to-external-system
Thanks.
You could try to create a Mule application that reads logs from CloudHub using CloudHub's API and pushes them to CloudWatch. The readme for the connector doesn't seem to mention an operation to put logs into CloudWatch, but if CloudWatch has a REST API for it -every AWS product has it- you could use it in your application.
This KB article shows how to get the logs from CloudHub: https://help.mulesoft.com/s/article/How-to-get-whole-Application-logs-from-Cloudhub-through-API
I have a java web application running on Tomcat deployed on an EC2 instance. Is there any way I can monitor/set alarms for when the web application goes down or stops responding? Essentially what I would like to do is to check if a HTTP request to the web app responds with status 200. If it does not respond with 200 (for a few times) then it should raise an alarm and send an e-mail to some ops people.
I know there are third party options like Nagois / uptimerobot that I could use but I wanted to know if there are any AWS offerings for this? Is it possible to set up such automated monitoring using AWS Cloud Watch? I could not find a way to do this based on what I read up about Cloud Watch. If this isn't the sort of thing Cloud Watch can handle, then is there another AWS service suited for this?
I think Port Monitoring Feature is available under AWS Beanstalk.
You can consider checking this http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.healthstatus.html
Ashutosh,
Ec2 is an IAAS service from AWS and you will not have an AWS offering to monitor your Tomcat server. However, you have custom-built solutions, which I think you are not looking for here.
However, if you are using an Application Load balancer or Beanstalk you get options to trigger alarms.
Yes , you can achieve it through a cloudwatch . collect your logs with a cloudwatch agent and upload it on cloudwatch logstream. below is the reference url for configuring cloudwatch agent.
https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Install-CloudWatch-Agent.html
After that with "create matrix filter" you can set up an email trigger as per your requirements.
