What is Ancientt
Ancientt is a tool to automate network testing tools, like
iperf3, in dynamic environments such as Kubernetes, Ansible and more to come dynamic environments.
Meaning that, if you want to test the network throughput with
iperf3 of your Kubernetes cluster, you can easily do that with Ancientt.
A simple “test definitions” file is used to tell Ancientt what exactly to do:
The above “test definitions” file tells Ancinett, to use the Kubernetes “runner”, to run a test from one randomly chosen Node to all the other Nodes (+ itself) in the Kubernetes cluster.
Test results are stored as CSV in files named after the given
namePattern to make it easy to split results by “server”, “client” and other available variables.
NOTE: It doesn’t have to be a Kubernetes cluster, an OpenShift cluster works as well.
Besides being able to run on Kubernetes and OpenShift, you can also provide an Ansible inventory file which also can be used to run tests on it.
The targeted hosts need to have the network testing tools installed as of right now. An example Ansible playbook can be found here: GitHub cloudical-io/ancientt –
Why did we create Ancientt
More and more people are moving to platforms like Kubernetes, OpenStack, OpenShift and others. The biggest problem we see in such installments is most of the time the network. Either because of performance, latency or general connectivity issues.
Ancientt right now allows us to easily run
iperf3 tests across whole Kubernetes and OpenShift clusters, and normal machines (through Ansible). Doing such tests manually takes a lot of time away from other potentially critical points that should be investigated.
With Ancientt you can easily run such tests faster. This should save you time and the results hopefully get you faster to a resolution of the problem and / or improving your network performance.
We’ll hopefully soon be able to add more network testing tools to the list, to make it even easier to run tests. E.g.,
siege and others, should be able to help with latency and performance tests.
Future of Ancientt
For the near future, we’ll focus on making it possible to get the results into Prometheus. This would allow for constant network testing, monitoring and alerting on issues.
If you have a good idea on how this can be achieved, feel free to comment on GitHub cloudical-io/ancientt – Issue ‘outputs: Prometheus’ #38.
As written in the Why did we create Ancientt section, we’ll look into adding more network testing tools.

All available documentation can be found in the GitHub cloudical-io/ancientt –
Ancientt can help you run
iperf3 tests, soon other network test tools as well, in a Kubernetes and OpenShift clusters, and using Ansible in an organized and quick way. Most importantly also collect the test results in an orderly fashion in output formats, like CSV, Excel, MySQL and SQLite.
