When installing, the plugin will attempt to copy a config file to /etc/newrelic/newrelic-neo4j.js. You can also use --print-config to print the current config file. In the file you will find:

module.exports = {
    pid: "/var/run/newrelic-neo4j.pid",
    log: "/var/log/newrelic-neo4j.log",

    // This is where you enter your license key
    license: "LICENSE KEY",

    // This is the name of the reporter
    name: "Database Name",

    // The database REST URL (usually http://domain.tld:7474 or https://domain.tld:7473)
    url: "Database URL",

    // OPTIONAL Set if the database requires an username and a password
    auth: {
        user: "neo4j",
        pass: "neo4j"
    },

    // Reporitng interval
    interval: 60
};

Usage

After installing and configuring you can simply run:

newrelic-neo4j

and it will attempt to read the config file from /etc/newrelic/newrelic-neo4j.js.

The options are:

    -h, --help      see those options
    -c, --config    set the config file location
    -o, --out       set location to output log file
    -p, --pid       set pid location (/var/run/newrelic-neo4j.pid)
    -f, --fork      forks the process into a daemon
    --stop          reads the pid and attempts to close the app
    --print-config  prints set config or default if none is provided
