Captures AWS Redshift statistics from Amazon CloudWatch and displays them in the AppDynamics Metric Browser.
<MachineAgent_Dir>/monitors/AWSRedshiftMonitorThe metricPrefix of the extension has to be configured as specified here. Please make sure that the right metricPrefix is chosen based on your machine agent deployment, otherwise this could lead to metrics not being visible in the controller.
In order to use the extension, you need to update the config.yml file that is present in the extension folder. The following is a step-by-step explanation of the configurable fields that are present in the
<MachineAgent_Dir>/monitors/AWSRDSMonitorThe metricPrefix of the extension has to be configured as specified here. Please make sure that the right metricPrefix is chosen based on your machine agent deployment, otherwise this could lead to metrics not being visible in the controller.
Provide accessKey(required) and secretKey(required) of your account(s), also provide displayAccountName(any name that represents your account) and
regions(required). If you are running this extension inside an EC2 instance which has IAM profile configured then you don’t have to configure accessKey and secretKey values, extension will use IAM profile to authenticate. You can provide multiple accounts and regions as below -
accounts: - awsAccessKey: "XXXXXXXX1" awsSecretKey: "XXXXXXXXXX1" displayAccountName: "TestAccount_1" regions: ["us-east-1","us-west-1","us-west-2"] - awsAccessKey: "XXXXXXXX2" awsSecretKey: "XXXXXXXXXX2" displayAccountName: "TestAccount_2" regions: ["eu-central-1","eu-west-1"]
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
true and provide the encryption key in
#Encryption key for Encrypted password. credentialsDecryptionConfig: enableDecryption: "true" encryptionKey: "XXXXXXXX"
Provide all valid proxy information if you use it. If not, leave this section as is.
proxyConfig: host: port: username: password:
To report metrics only from specific dimension values, configure the
dimension section as below -
dimensions: - name: "latency" displayName: "Latency" values: ["short", "long", "medium"] - name: "NodeID" displayName: "Node ID" values: ["Leader", "Compute-0", "Compute-1"] - name: "ClusterIdentifier" displayName: "Cluster ID" values: ["my-redshift"] - name: "service class" displayName: "Service Class" values: ["6","5","15","14"] - name: "Stage" displayName: "Query Execution Stage" values: [""] - name: "wmlid" displayName: "Workload Mgmt Queue" values: [""]
If these fields are left empty
, the metrics which require that dimension will not be reported.
In order to monitor everything under a dimension, you can simply use “.*” to pull everything from your AWS Environment.
Configure the metrics section.
For configuring the metrics, the following properties can be used:
|Property||Default value||Possible values||Description|
|alias||metric name||Any string||The substitute name to be used in the metric browser instead of metric name.|
|statType||“ave”||“AVERAGE”, “SUM”, “MIN”, “MAX”||AWS configured values as returned by API|
|aggregationType||“AVERAGE”||“AVERAGE”, “SUM”, “OBSERVATION”||Aggregation qualifier|
|timeRollUpType||“AVERAGE”||“AVERAGE”, “SUM”, “CURRENT”||Time roll-up qualifier|
|clusterRollUpType||“INDIVIDUAL”||“INDIVIDUAL”, “COLLECTIVE”||Cluster roll-up qualifier|
|multiplier||1||Any number||Value with which the metric needs to be multiplied.|
|convert||null||Any key value map||Set of key value pairs that indicates the value to which the metrics need to be transformed. eg: UP:0, DOWN:1|
|delta||false||true, false||If enabled, gives the delta values of metrics instead of actual values.|
- name: "CPUUtilization" alias: "CPU Utilization (Unit - %; StatType - ave)" statType: "ave" delta: false multiplier: 1 aggregationType: "AVERAGE" timeRollUpType: "AVERAGE" clusterRollUpType: "INDIVIDUAL"
All these metric properties are optional, and the default value shown in the table is applied to the metric(if a property has not been specified) by default.
CloudWatch metrics are delivered on a best-effort basis. This means that the delivery of metrics is not guaranteed to be on-time.
There may be a case where the metric is updated in CloudWatch much later than when it was processed, with an associated delay.
For Redshift, the delay can be 4 - 5 minutes. There is a possibility that the extension does not capture the metric, which is the reason there is a time window. The time window allows
the metric to be updated in CloudWatch before the extension collects it.
metricsTimeRange: startTimeInMinsBeforeNow: 9 endTimeInMinsBeforeNow: 4
This field is set as per the defaults suggested by AWS. You can change this if your limit is different.
The maximum number of retry attempts for failed requests that can be re-tried.
Please avoid using tab (\t) when editing yaml files. Please copy all the contents of the config.yml file and go to Yaml Validator . On reaching the website, paste the contents and press the “Go” button on the bottom left.
If you get a valid output, that means your formatting is correct and you may move on to the next step.

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
Please look at the troubleshooting document and make sure that everything is followed correctly.
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.
Stop the running machine agent.
Delete all existing logs under
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">
Start the machine agent and please let it run for 10 mins. Then zip and upload all the logs in the directory
Attach the zipped
<MachineAgent>/conf/* directory here.
