.NET Agent for Linux Environment Variables

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

Agent Account Name

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

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.

Agent Account Password  

Specifies the account access key for the Controller. 

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.

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.

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.  

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.

Analytics SSL Enabled

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

Analytics Hostname

Specifies the hostname or IP address of the analytics host.

Analytics Port

Specifies the port number of the analytics port.

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. 

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. 

Controller SSL Enabled 

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

Controller SSL Certfile

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

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). 

HTTP Proxy Host

The name of the proxy host.

HTTP Proxy Port

The port number of the proxy.

HTTP Proxy User

The name of the user that connects to the proxy.

HTTP Proxy Password

The password of the user that connects to the proxy.

Sample Agent Configuration File

The following environment variables can be set in the AppDynamicsConfig.json file:

• APPDYNAMICS_CONTROLLER_HOST_NAME
• APPDYNAMICS_CONTROLLER_PORT
• APPDYNAMICS_CONTROLLER_SSL_ENABLED
• APPDYNAMICS_CONTROLLER_SSL_CERTFILE
• APPDYNAMICS_CONTROLLER_SSL_CERTDIR

The example file below demonstrates how to set these variables:

"controller":
{
   "host": "ControllerHost",
    "port": 8181,
     "account": "customer1",
      "password": "test",
       "ssl": true,
       "certdir": "/opt/appdynamics/dotnet/conf/",
       "certfile": "/opt/appdynamics/dotnet/conf/cacerts.pem",
        "enable_tls12": true,
        "proxy":
		{
			"host" : "proxy",
			"port" :900,
			"authentication" :
			{
				"username" : "user",
				"domain"  : "domainname",
				"password" :"pwd"
			}
		}
}
