Create a Gatling feeder file using REST calls
View gatlingGeneratedFeeder.scala
Basic blocks of code that will build a CSV file using repsonse data from API calls
This is a "one-off" process, meaning you will
1. run Gatling script to generate CSV file using REST calls (usually POSTS, but GETS or datbase queries could work )
2. copy the file into your project
3. compile and run Gatling

What is the difference between "express": "^4.13.3" and "express": "~4.13.3" ?
What happens if I use `npm install <package> --save` instead of `npm install <package> --save-dev` ?

Take note of length - it is used as a String[] property > strings.length AND as a method for a String
array element > strings[i].length().
public Map<String, String> pairs(String[] strings) {
Map<String,String> map = new HashMap<String,String>();
for (int i = 0; i < strings.length; i++ ) {
if (strings[i].length() == 1 ) {
Character first = strings[i].charAt(0);

// create an alternative method for getting a list of defined enums to avoid system creating a clone of the String array
// this is the .values() method
public enum Car {
// normally what would happen
public static Car[] values() {

View ec2_getIP
While you can get the public and private IP address of your Amazon EC2 instance via the AWS Console, it may be extremely useful to query it from anywhere you can make an HTTP request, such a shell script. The operation is really simple, just make a GET request to the following URL from within your EC2 instance:
Local IP:
Public IP:
I often use this feature to pre-configure services and update configuration files, as in EC2 you get a new IP Address each time you reboot
