    This topic is a reference for the configuration properties for the .NET Agent for Linux that can be set using system environment variables. 

    Agent Account Name

    Specifies the account name for the SaaS or multi-tenant Controller.

    Environment Variable: APPDYNAMICS_AGENT_ACCOUNT_NAME
    Type: String
    Default: For single-tenant Controllers, the agent assumes the default of customer1 if you do not specify an account name.
    Required: Only for SaaS or multi-tenant Controllers.

    Agent Application Name

    Specifies the business application you use in the Controller. If the application name does not exist, the Controller will create it when the agent registers. See Overview of Application Monitoring

    Environment Variable: APPDYNAMICS_AGENT_APPLICATION_NAME
    Type: String
    Default: None
    Required: Yes

    Agent Account Password  

    Specifies the account access key for the Controller. 

    Environment Variable: APPDYNAMICS_AGENT_ACCOUNT_ACCESS_KEY
    Type: String
    Default: None
    Required: Yes

    Agent Node Name

    The name of the node.

    In general, the node name must be unique within the business application and physical host. To use the same node name for multiple nodes on the same physical machine, create multiple virtual hosts using the Unique Host ID property. See Unique Host ID.

    Environment Variable: APPDYNAMICS_AGENT_NODE_NAME
    Type: String

    Default: None
    Required: Yes

    Agent Reuse Node Name

    Set this environment variable to true to reuse node names in AppDynamics. When you set the property to true, you don't need to supply a node name, but you do need to provide a node name prefix using APPDYNAMICS_AGENT_REUSE_NODE_NAME_PREFIX.

    This property is useful for monitoring environments where there are many CLRs with short life spans. When true, AppDynamics reuses the node names of historical CLRs for new CLRs. Reusing node names avoids a proliferation of differently named nodes in AppDynamics over time, particularly when the nodes are essentially identical processes that run over different times. 

    AppDynamics generates a node name with App, Tier, and Sequence number. The node names are pooled. For example, the sequence numbers are reused when the nodes are purged (based on the node lifetime).

    When the .NET Agent for Linux starts up, it logs output to the console until it registers with the Controller and the Controller generates the node name. 

    The Controller reuses node names based on the node.retention.period property. See Historical and Disconnected Nodes.

    Environment Variable: APPDYNAMICS_AGENT_REUSE_NODE_NAME
    Type: Boolean

    Default: False
    Required: No

    Example: Using the following environmental variable specifications, the Controller generates a node name with the prefix reportGen. Node names will have suffixes --1, --2, and so on, depending on the number of nodes are running in parallel. The name of a node that is shut down and qualifies as a historical node may be reused by a new node. 

    APPDYNAMICS_AGENT_REUSE_NODE_NAME=true

    APPDYNAMICS_AGENT_REUSE_NODE_NAME_PREFIX=reportGen

    Agent Reuse Node Name Prefix

    When you configure the agent to reuse node names, use this property to specify the prefix the Controller uses to generate node names dynamically.  

    Environment Variable: APPDYNAMICS_AGENT_REUSE_NODE_NAME_PREFIX
    Type: String

    Default: None
    Required: When APPDYNAMICS_AGENT_REUSE_NODE_NAME=true
    Example: Using the following environmental variable specifications, the agent directs the Controller to generate a node name with the prefix
    reportGen. Node names will have suffixes --1, --2, and so on, depending on how many nodes are running in parallel.

    APPDYNAMICS_AGENT_REUSE_NODE_NAME=true

    APPDYNAMICS_AGENT_REUSE_NODE_NAME_PREFIX=reportGen

    Agent Tier Name

    Specifies the name of the tier that this .NET node belongs to. Note that this is not the deployment name on the application server.

    Environment Variable: APPDYNAMICS_AGENT_TIER_NAME
    Type: String

    Default: None

    Required: Yes

    Analytics SSL Enabled

    Specifies whether or not the .NET Agent for Linux sends the default transaction data to the Analytics Agent via SSL.


    Environment Variable: APPDYNAMICS_ANALYTICS_SSL_ENABLED
    Type: String
    Default: False
    Required: No

    Analytics Hostname

    Specifies the hostname or IP address of the analytics host.

    Environment Variable: APPDYNAMICS_ANALYTICS_HOST_NAME
    Type: String
    Default: None
    Required: No

    Analytics Port

    Specifies the port number of the analytics port.

    Environment Variable: APPDYNAMICS_ANALYTICS_PORT
    Type: Positive integer
    Default: None
    Required: No


    Controller Hostname

    Specifies the hostname or the IP address of the AppDynamics Controller. For an on-premises Controller, use the value for Application Server Host Name you provided when you installed the Controller. If you use the AppDynamics SaaS Controller, see the Welcome email from AppDynamics for the name of your Controller. 

    Environment Variable: APPDYNAMICS_CONTROLLER_HOST_NAME
    Type: String

    Default: None
    Required: Yes, may also be set in the agent AppDynamicsConfig.json file as "host".

    Controller Port Number

    Specifies the HTTP(S) port of the AppDynamics Controller. If the APPDYNAMICS.CONTROLLER.SSL.ENABLED environment variable is set to true, specify the HTTPS port of the Controller; otherwise, specify the HTTP port. 

    Environment Variable: APPDYNAMICS_CONTROLLER_PORT
    Type: Positive Integer
    Default: 8090

    • For On-premises installations, the defaults are port 8090 for HTTP and port 8181 for HTTPS.
    • For the SaaS Controller, use port 80 for HTTP or port 443 for HTTPS.

    Required: Yes, may also be set in the agent AppDynamicsConfig.json file as "port".

    Controller SSL Enabled 

    When set to true enables encryption over SSL between the agent and the Controller.

    Environment Variable: APPDYNAMICS_CONTROLLER_SSL_ENABLED
    Type: Boolean
    Default: false

    Required: No, may also be set in the agent AppDynamicsConfig.json file as "ssl".

    Controller SSL Certfile

    The path to the folder containing certificate files used to connect to the SSL-enabled Controller.

    Default: None

    Required: No. Optionally, you can set in the agent AppDynamicsConfig.json file as "certfile".

    Controller SSL Certdirectory

    The path to the folder containing the certificate directory used to connect to the SSL-enabled Controller.

    Certificate directory values are valid only if you do not input certificate files (APPDYNAMICS_CONTROLLER_SSL_CERTFILE). 

    Environment Variable: APPDYNAMICS_CONTROLLER_SSL_CERTDIR
    Type: String
    Default: None

    Required: No. Optionally, you can set in the agent AppDynamicsConfig.json file as "certdir".
