- 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
ndtDaemonSet 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.
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 <start> <stop> <step> <target> <period>
Option descriptions:
- <start>: The initial/starting number of concurrent NDT clients to launch against server.
- <stop>: The maximum number of concurrent tests to launch against server.
- <step>: Increments the number of concurrent tests against <server> by this amount each <period> from <start> until <stop> count is reached.
- <target>: The target server to run the tests against. Default: mlab3v4-lga0t.mlab-sandbox.measurement-lab.org.
- <period>: The amount of time to run each incremental number of concurrent tests before adding <step> more concurrent tests.
