Captures statistics for EC2 instances from Amazon CloudWatch and displays them in the AppDynamics Metric Browser.
Before the extension is installed, the prerequisites mentioned here need to be met. Please do not proceed with the extension installation if the specified prerequisites are not met.
Please give the following permissions to the account being used to with the extension.
The extension needs to be able to connect to AWS Cloudwatch in order to collect and send metrics. To do this, you will have to either establish a remote connection in between the extension and the product, or have an agent on the same machine running the product in order for the extension to collect and send the metrics.
Please place the extension in the "monitors" directory of your Machine Agent installation directory. Do not place the extension in the "extensions" directory of your Machine Agent installation directory.
In order to use the extension, you need to update the config.yml file that is present in the extension folder. The following is an explanation of the configurable fields that are present in the config.yml file.
Note: Please avoid using tab (\t) when editing yaml files. You may want to validate the yaml file using a yaml validator.
|accounts||Fields under this section can be repeated for multiple accounts config|

Below is an example config for monitoring multiple accounts and regions:
#prefix used to show up metrics in AppDynamics. This will create this metric in all the tiers, under this path #metricPrefix: "Custom Metrics|Amazon EC2|" #This will create it in specific Tier/Component.

Configure the "COMPONENT_ID" under which the metrics need to be reported. This can be done by changing the value of
<COMPONENT_ID> in metricPrefix: "Server|Component:<COMPONENT_ID>|Custom Metrics|Amazon EC2|".
metricPrefix: "Server|Component:100|Custom Metrics|Amazon EC2|"
Configure "awsAccessKey" and "awsSecretKey". If you are running this extension inside an EC2 instance which has IAM profile configured then you don't have to configure these values, extension will use IAM profile to authenticate.
Configure "regions". Extension collects metrics from all the regions configured here.
If you want to encrypt the "awsAccessKey" and "awsSecretKey" then follow the "Credentials Encryption" section and provide the encrypted values in "awsAccessKey" and "awsSecretKey". Configure "enableDecryption" of "credentialsDecryptionConfig" to true and provide the encryption key in "encryptionKey"
Typical metric path: Application Infrastructure Performance|<Tier>|Custom Metrics|Amazon EC2|<Account Name>|<Region>|Instance|<instance id or name> followed by the metrics defined in the link below:
Please visit this page to get detailed instructions on password encryption. The steps in this document will guide you through the whole process.
Once you encrypt the access key and secret key add the excrypted values to the awsAccessKey and awsSecretKey respectively. Based on the "enableDecryption" in "credentialsDecryptionConfig" section extension will decide if it has to decrypt the keys or not. Provide the encryption key used to encrypt in the "encryptionKey" of "credentialsDecryptionConfig".
Workbench is an inbuilt feature provided with each extension in order to assist you to fine tune the extension setup before you actually deploy it on the controller. Please review the following document on How to use the Extensions WorkBench
If after going through the Troubleshooting Document you have not been able to get your extension working, please file a ticket and add the following information.
Please provide the following in order for us to assist you better.
1. Stop the running machine agent. 2. Delete all existing logs under <MachineAgent>/logs. 3. Please enable debug logging by editing the file <MachineAgent>/conf/logging/log4j.xml. Change the level value of the following <logger> elements to debug. <logger name="com.singularity"> <logger name="com.appdynamics"> 4. Start the machine agent and please let it run for 10 mins. Then zip and upload all the logs in the directory <MachineAgent>/logs/*. 5. Attach the zipped <MachineAgent>/conf/* directory here. 6. Attach the zipped <MachineAgent>/monitors/ExtensionFolderYouAreHavingIssuesWith directory here.
