Manual Strategy

By default, the tierNameStrategy is manual, which uses the deployment name or tierName parameter to set the tier name.

• If tierName is not provided, then use deployment name as tiername .
• If tierName is provided in an instrumentation rule, then use it.

For example in this spec, <deployment name> is the default tier name applied to the ecom and groceries namespace , and BookStore is the tier name applied to the books namespace.

apiVersion: cluster.appdynamics.com/v1alpha1
kind: Clusteragent
metadata:
name: k8s-cluster-agent
namespace: appdynamics
spec:
appName: "<cluster-name>"
# ...
# auto-instrumentation config
instrumentationMethod: Env
nsToInstrumentRegex: ecom|books|groceries
tierNameStrategy: manual
instrumentationRules:
- namespaceRegex: books
tierName: BookStore

Label Strategy

This option uses the label parameter as the tier name strategy. To use the label option, specify a value in the tierNameLabel parameter. The tierNameLabel value refers to a label specified in the workload spec.

• If spec.tierNameLabel is provided, then use it (unless overwritten in an instrumentation rule).
• If tierNameLabel is provided in an instrumentation rule, then use it.

For example in this spec, the workload spec label tiername is used to set the tier name in the ecom and groceries namespaces, and the label tier is used in the books namespace.

apiVersion: cluster.appdynamics.com/v1alpha1
kind: Clusteragent
metadata:
name: k8s-cluster-agent
namespace: appdynamics
spec:
appName: "<cluster-name>"
# ...
# auto-instrumentation config
instrumentationMethod: Env
nsToInstrumentRegex: ecom|books|groceries
tierNameStrategy: label
tierNameLabel: tiername
instrumentationRules:
- namespaceRegex: books
tierNameLabel: tier

For an application deployed to the ecom or groceries namespaces that sets the label tiername (shown in this Deployment spec snippet), it reports to the eCommerce tier in the Controller's Dashboard.

apiVersion: apps/v1
kind: Deployment
metadata:
name: ecom-app
labels:
tiername: eCommerce
spec:
