Collect Default Node.js Transaction Data

To configure the Node.js Agent to send the default transaction data to the Analytics Agent, modify the require statement in your application.

Add these variables with the proper values to point to your Analytics Agent:

analytics: {
    host: <analyticsHostName>,
    port: <analyticsPort>,
    ssl: <true || false> 
}

The Analytics Agent can be on the same host as the Node.js Agent or on a different host. See Install the Node.js Agent.

Configure Data Limits

You can also configure the Node.js Agent to set limits on data sent to the Analytics Agent with these properties correlated to environment variables.

Your require statement should look similar to the following example where your Analytics Agent is on localhost and listening on Port 9090:

require ("appdynamics").profile({
    controllerHostName: '<Controller host name>',
    controllerPort: <Controller port number>,
    controllerSslEnabled: false, // Set to true if controllerPort is SSL
    accountName: '<AppDynamics account name>',
    accountAccessKey: '<AppDynamics account key>', // Required
    applicationName: '<Your application name>',
    debug: false,
    tierName: '<Choose a tier name>',
    nodeName: '<Choose a node name>', // The Controller appends the node name with a unique number
    analyticsMaxSegmentSizeInBytes: 20,
    analyticsMaxSegmentsPerRequest: 20,
    analyticsMaxMessageSizeInBytes: 100,
    analytics: {
        host: 'localhost',
        port: 9090 },
    logging: {
        'logfiles': [
        {'root_directory': '/tmp/appd', 'filename': 'echo_%N.log', 'level': 'TRACE', 'max_size': 5242880, 'max_files': 10 },
        { 'root_directory': '/tmp/appd', 'filename': 'protobuf_%N.log', 'level': 'TRACE', 'max_size': 5242880, 'max_files': 10, 'channel': 'protobuf' }]
             }
});

Collect Node.js Data Collectors

You can also collect additional data from your Node.js business transactions by using the Node.js API. To configure Transaction Analytics data collectors for Node.js, see txn.addAnalyticsData() in the Node.js Agent API Reference.
