AWS (Legacy)

The AWS (Legacy) StackPack has been deprecated. It is recommended to use the new AWS integration.
Overview
Amazon Web Services (AWS) is a major cloud provider. This StackPack enables in-depth monitoring of AWS services.
Data flow
Three AWS Lambdas collect topology data from AWS and push this to StackState:
stackstate-topo-cron scans AWS resources every hour using the AWS APIs and pushes this to StackState.
stackstate-topo-cwevents listens to CloudWatch events, transforms the events and publishes them to Kinesis.
stackstate-topo-publisher publishes retrieved topology data from a Kinesis stream to StackState.
StackState translates incoming data into topology components and relations.
The StackState CloudWatch plugin pulls available telemetry data per resource at a configured interval from AWS.
StackState maps retrieved telemetry (metrics) onto the associated AWS components and relations.
Setup
Prerequisites
To set up the StackState AWS integration, you need to have:
AWS CLI version 2.0.4 or later is installed on the environment where StackState is running.
An AWS user with the required access to retrieve CloudWatch metrics:
cloudwatch:GetMetricData
cloudwatch:ListMetrics
A policy file to create a user with the correct rights can be downloaded from the the StackState UI screen StackPacks > Integrations > AWS.
An AWS user with the required access rights to install StackState monitoring in your account. See AWS IAM policies, below.
Proxy URL
If your StackState instance is behind a proxy, you need to configure the proxy URL and port for the AWS authorization to work. You can configure a proxy URL environment variable or JVM system property.
Environment variable HTTP_PROXY and/or HTTPS_PROXY
Pass following properties when starting StackState instance -Dhttp.proxyHost -Dhttp.proxyPort and/or -Dhttps.proxyHost -Dhttps.proxyPort
Install
Install the AWS StackPack from the StackState UI StackPacks > Integrations screen. You will need to provide the following parameters:
AWS instance name - the user-defined name of the AWS account shown in configurations such as views.
AWS Access Key id - the access key for the user for retrieving CloudWatch metrics.
AWS Secret Access Key - the secret key for the user for retrieving CloudWatch metrics.
AWS Role ARN - Optional: IAM role ARN - the ARN of the IAM role to be used
Deploy AWS Cloudformation stacks
The StackState AWS Cloudformation stacks are deployed on your AWS account to enable topology monitoring. There are two options for StackState monitoring:
​Full install - all changes to AWS resources will be picked up and pushed to StackState.
​Minimal install - changes will be picked up only at a configured interval.
Full install
A full installation will install the following CloudFormation Stacks:
stackstate-topo-cron
stackstate-topo-kinesis
stackstate-topo-cloudtrail
stackstate-topo-cwevents
stackstate-topo-publisher
Follow the steps below to complete a full install:
1.Download the manual installation zip file and extract it. This is included in the AWS StackPack and can be accessed at the link provided in StackState after you install the AWS StackPack.
2.Make sure the AWS CLI is configured with the proper account and has the default region set to the region that should be monitored by StackState.
For further information on authentication via the AWS CLI, see using an IAM role in the AWS CLI (docs.aws.amazon.com).
3.From the command line, run the command:
1
./install.sh {{config.baseUrl}} {{config.apiKey}} {{configurationId}}
Copied!
If you wish to use a specific AWS profile or an IAM role during installation, run either of these two commands:
1
AWS_PROFILE=profile-name ./install.sh {{config.baseUrl}} {{config.apiKey}} {{configurationId}}
2
AWS_ROLE_ARN=iam-role-arn ./install.sh {{config.baseUrl}} {{config.apiKey}} {{configurationId}}
Copied!
These environment variables have the same names used by the AWS_CLI utility and will be overridden with options:
--profile
--role-arn
--session-name
--external-id
Minimal install
The minimal installation is useful when less permissions are available. This installs only the stackstate-topo-cron Cloudformation stack, which means StackState's topology will only get a full topology update every hour. Updates between the hour are not sent to StackState.
Follow the steps below to complete a minimal install:
1.Download the manual installation zip file and extract it. This is included in the AWS StackPack and can be accessed at the link provided in StackState after you install the AWS StackPack.
2.Make sure the AWS CLI is configured with the proper account and has the default region set to the region that should be monitored by StackState.
For further information on authentication via the AWS CLI, see using an IAM role in the AWS CLI (docs.aws.amazon.com).
3.From the command line, run the command:
1
./install.sh --topo-cron-only {{config.baseUrl}} {{config.apiKey}} {{configurationId}}
Copied!
You can also optionally specify the following:
--topo-cron-bucket - a custom S3 bucket to be used during deployment.
--topo-cron-role - a custom AWS IAM role. Note that the role must have an attached policy like that specified in the file sts-topo-cron-policy.json included in the manual install zip file.
If you wish to use a specific AWS profile or an IAM role during installation, run either of these two commands:
1
AWS_PROFILE=profile-name ./install.sh --topo-cron-only {{config.baseUrl}} {{config.apiKey}} {{configurationId}}
2
AWS_ROLE_ARN=iam-role-arn ./install.sh --topo-cron-only {{config.baseUrl}} {{config.apiKey}} {{configurationId}}
Copied!
These environment variables have the same names used by the AWS_CLI utility and will be overridden with options:
--profile
--role-arn
--session-name
--external-id
AWS IAM Policies
The following AWS policies can be downloaded during the installation of the AWS StackPack in your StackState instance:
Full install - StackStateIntegrationPolicyInstall.json
Minimal install - StackStateIntegrationPolicyTopoCronInstall.json
Minimal set of policies - StackStateIntegrationPolicyTopoCronMinimal.json S3 bucket and role are provided by user.
Uninstall a full install - StackStateIntegrationPolicyUninstall.json
Uninstall a minimal install - StackStateIntegrationPolicyTopoCronUninstall.json
Timeout
The default read timeout for AWS is set to 30 seconds. You can specify custom read timeout with the AWS_CLI_READ_TIMEOUT environment variable.

AWS lambdas
The StackState AWS integration installs the following AWS lambdas:
Lambda
Description
stackstate-topo-cron
Scans the initial topology based on an interval schedule and pushes to StackState.
stackstate-topo-cwevents
Listens to CloudWatch events, transforms the events and publishes them to Kinesis. Full install only.
stackstate-topo-publisher
Pushes topology from a Kinesis stream to StackState. Full install only.
Costs
The AWS lightweight agent uses Amazon resources (Lambda and Kinesis) for which Amazon will charge a minimal fee. Amazon also charges a fee for the use of CloudWatch metrics. Metrics are only retrieved when viewed or when a check is configured on a CloudWatch metric.
AWS views in StackState
When the AWS integration is enabled, three views will be created in StackState for each instance of the StackPack.
AWS - [instance_name] - All - includes all resources retrieved from AWS by the StackPack instance.
AWS - [instance_name] - Infrastructure - includes only Networking, Storage and Machines resources retrieved from AWS by the StackPack instance.
AWS - [instance_name] - Serverless - includes only S3 buckets, lambdas and application load balancers retrieved from AWS by the StackPack instance.
AWS actions in StackState
Components retrieved from AWS will have an additional action available in the component context menu and component details pane on the right-hand side of the screen. This provides a deep link through to the relevant AWS console at the correct point.
For example, in the StackState Topology Perspective:
Components of type aws-subnet have the action Go to Subnet console, which links directly to this component in the AWS Subnet console.
Components of type ec2-instance have the action Go to EC2 console, which links directly to this component in the EC2 console.
Tags and labels
The AWS StackPack converts tags in AWS to labels in StackState. In addition, the following special tags are supported:
Tag
Description
stackstate-identifier
Adds the specified value as an identifier to the StackState component
stackstate-environment
Places the StackState component in the environment specified

Uninstall
To uninstall the StackState AWS StackPack, click the Uninstall button from the StackState UI StackPacks > Integrations > AWS screen. This will remove all AWS specific configuration in StackState.
Once the AWS StackPack has been uninstalled, you will need to manually uninstall the StackState AWS Cloudformation stacks from the AWS account being monitored. To execute the manual uninstall follow these steps:
1.Download the manual installation zip file and extract it. This is included in the AWS StackPack and can be accessed at the link provided in StackState after you install the AWS StackPack.
2.Make sure the AWS CLI is configured with the proper account and has the default region set to the region that should be monitored by StackState.
For further information on authentication via the AWS CLI, see using an IAM role in the AWS CLI (docs.aws.amazon.com).
3.From the command line, run the below command to de-provision all resources related to the StackPack instance:
1
./uninstall.sh {{configurationId}}
