CLI load test suite for statsd node clients

I wrote this project in order to test the performance of multiple node.js clients for statsd. I wanted to find out the performance differences between the available node.js clients for statsd so I made this CLI tool which makes it easy to switch options for each test. It basically performs a load test based on the input from the CLI.

The clients that are currently supported are:

• lynx
• node-statsd-client
• node-statsd
• statsd-client

You can run this test suite by cloning this project and running it like this:

node test_statsd_client.js -l <library> -d <number of workers> -t <timeout>

For example you can test lynx by running:

node test_statsd_client.js -l lynx -d 10000 -t 1000

This will spawn 10.000 intervals through setInterval which will send a stat to statsd every 1000ms.

There are multiple options which can be overridden through the command line. The options are as follows:

-e <string>     The type of test to execute, either load or stress (default execute = load)
-d <number>     Number of setIntervals to spawn. (default depth = 1000)
-t <number>     Timeout for the interval (default timeout = 1000)
-r <number>     The time to run the tests for. (default runtime = 15*60*1000 --> 15 minutes)
-h <string>     The host statsd is running on. (default host = localhost)
-p <number>     The port statsd is running on. (default port = 8125)
