Manage Tier Naming Rules

You can use the Tier Naming Rule functionality to customize the tier name of any managed Java process. Each tier rule maps to a specific server type. Tier Naming Rules allows you to create Rego policies so that the Agent Installer can discover tier names. To do that, the tier naming format or rule condition must have a valid Rego expression. AppDynamics recommends recreating Rego Policies using Tier Naming Rules. See Rego Policy Language.

For information on the Agent Installer API, see Agent Installer Platform Service API.

Tier Naming Format

Format	Description	Example
`tier-name-format`	The format contains only `literals` and the tier name appears the same as the format.	`tier-name-format`
`tier-<AppServerType>-format`	The mix of `literals` and `attributes`. The tier name is evaluated after passing the attribute and replaces the value of the attribute. Attributes are defined within the angular bracket `<AppServerType>`.	`tier-tomcat-format for tomcat application server` `tier-jboss-format for jboss application server` `tier-glassfish-format for glassfish application server` `tier-java-format for plain java application`
`input.CmdlineArray[count(input.CmdlineArray) - 1]`	The expression is made inside the ` `. This does not have an attribute, and there is no change in the expression.	`"CmdlineArray": [ "/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el7_8.x86_64/jre/bin/java", "-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager", "-classpath", "/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el7_8.x86_64/lib/tools.jar:/home/Ecommerce.jar", "EcommerceApplication" ]` CODE Assuming the command line is the value above, the tier name format is `EcommerceApplication`.
`<CmdlineArray>[count(<CmdlineArray>) - 1]`	The expression is made inside the ` `. The attributes are parsed.	`"CmdlineArray": [ "/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el7_8.x86_64/jre/bin/java", "-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager", "-classpath", "/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el7_8.x86_64/lib/tools.jar:/home/Ecommerce.jar", "EcommerceApplication" ]` CODE Assuming the command line is the value above, the tier name format is `EcommerceApplication`.

Add New Tier Naming Rules

Go to the Tier Naming Rules tab.
Click + Add New Rule.
Enter the following:
1. Rule Name
2. Tier Naming Format: Use any characters, words, and variables to define your naming format.
3. Application Server Types: Select the application server type that the naming rule will apply to.
4. Conditions: Select values that match the conditions that will be added to the tier.
  
  All string comparisons are case sensitive.
5. Application Scope: Only tiers in the selected applications will be evaluated against the conditions.
Click Create rule.
Scenario 1: If an existing tier name (Tier 1) is disabled, and a new tier name (New Tier 1) is discovered by the tier rule, the new tier (New Tier 1) will be disabled by default.
Scenario 2: If an existing tier name (Tier 1) is disabled, and it is modified to an existing tier name (Tier 2), by the change of tier rules the status of the tier name (Tier 2) will be not change.
