# NDT Load Test

## Pre-Requisites

* Access to at least one M-Lab sandbox node from which you will launch the

  load test.

* **IMPORTANT**: disable the TxController of the target ndt-server. If you do

  not do this, the load testing will not work. One easy way to do this is to

  manually edit the `ndt` DaemonSet in the mlab-sandbox cluster (`kubectl

  edit ds ndt`) and set `-txcontroller.max-rate=0`. This will affect all

  ndt-servers in the mlab-sandbox cluster, so don't forget to undo this

  change when you are done.

## Running tests

On the M-Lab sandbox node, run something like the following:

```

# docker run --rm --workdir=/root/bin --net=host --tty \

    measurementlab/node-loadtesting:v1.0.0 ./run.sh 50 250 10

```

run.sh accepts five arguments, the first three of which are required:

```

./run.sh     

```

Option descriptions:

* _\_: The initial/starting number of concurrent NDT clients to launch

  against _server_.

* _\_: The maximum number of concurrent tests to launch against _server_.

* _\_: Increments the number of concurrent tests against _\_ by

  this amount each _\_ from _\_ until _\_ count is reached.

* _\_: The target server to run the tests against.

  Default: mlab3v4-lga0t.mlab-sandbox.measurement-lab.org.

* _\_: The amount of time to run each incremental number of concurrent

  tests before adding _\_ more concurrent tests.
