I want to simulate User growth on my website
So I need a cron job on my linux webserver that executes a shell script that retrieves a value from my local mysql table, adds a number to it and writes it back. The cron should run all 5 minutes.
For adding the number, there should be a function with the following parameters:
1. probability that number should be added (like tossing a coin).
if prob = 1, number will be added 100% sure
if prob = 0, nothing happens, no number will be added
if prob = 0.5, number will be added with a 50% probability. Means, assuming the script runs every 5 minutes, number would be added roughly every second run of the cron.
etc. etc.
2. size of number: should be random number. Range should be defined by upper and lower bound.
----EXAMPLE---
var_prob = 0.5;
var_upper = 50;
var_lower = 10;
function determine_if_number_should_be_added(prob) as boolean {
out = calculate(prob);
}
if (determine_if_number_should_be_added(prob) == TRUE) {
number_to_add = generate_random_number(var_lower, var_upper);
old = mysql(retrieve value)
new = old +number_to_add;
mysql(UPDATE...);
}
