OctoPerf v12.8 - Datadog, Json Path and sub samples

It's been a while since the last update post in july 2021, not that we haven't updated OctoPerf since then but the additions we've made are not easy to share in a blog. Allow me to take an example.

JMeter import

The thing that kept us the most busy over the years is finding the perfect way to import a JMeter project into our data model. We need to do this in order to:

  • Allow you to manipulate your virtual users in our interface even when they come from JMeter,
  • Execute each Threadgroup/Virtual user in a separate docker container to make our runtime resilient and scalable (this allows us to predict resource consumption better and allocate machines accordingly),
  • Offer a configurable report with filters instead of a static HTML.

But we must make sure to maintain the same behavior for all functionalities. And at the same time we must avoid negative impacts on our non-JMeter users (like added UI complexity, or regressions). That seems simple enough at first glance but it gets harder when you consider that JMeter allows you to put any configuration anywhere but with a different scope. For instance you can have header managers configured this way:


Once imported in OctoPerf each Threadgroup will be a distinct Virtual User, and we need to consider carefully what to do with these headers, we must find a way to preserve the same behavior in OctoPerf.

OctoPerf v12.4 - Integrate with Postman, Microsoft Teams, Grafana and Dynatrace

The focus of OctoPerf 12.4 is on integrations, first in regards to creating test scripts through our new Postman import released a few weeks ago. Through postman we also open OctoPerf to swagger and open API imports.

Microsoft Teams is also on the menu in terms of alerting before/after the tests, but the main dish is the backend listeners. Through these you can have our load generators send metrics to your own database in real time during the test. And by database I also mean several APM tools, like dynatrace, datadog and others.

On top of all this we've upgraded the scheduler to be able to chain several load tests one after another, upgraded to JMeter 5.4.1 and a couple of other features detailed below.


API testing with OctoPerf

API testing has always been possible in OctoPerf but to enable faster test design we've worked on a Postman integration.

The way it works is that you can import an existing postman collection into OctoPerf and we will create all the associated requests automatically for you:


OctoPerf v12.2 - Flexible license sharing, improved VU validation, XPath and JQuery

We've been working a lot behind the scenes for this release because we wanted to address the license sharing issue. Up until today it was only possible to ask us to share the license for you and sharing could only share every license you own. We had to completely refactor the way we handle licenses to allow you to decide on your own to share all or a fraction of your subscriptions.

But that's not all, we also worked on a VU validation with multiple iterations. XPath and JQuery processors were only available when importing from JMeter but now you can create them directly in OctoPerf's UI and use them in your automatic correlation rules. And many other features that we will highlight in this post.


Share a license

The main course is the new license sharing system. It used to be possible to share a license by asking our support team to share all your licenses with another account, but even if we always answer fast that was not convenient and even worse, you had to share all your licenses with the new account.

For these reasons, we've worked on a system that is fully flexible, allowing you to share some or all your subscriptions with another OctoPerf account:


OctoPerf v12 - Scheduler, slack integration and UI upgrade

It's been some time since our latest major release, in fact OctoPerf v12 is probably our biggest/longest coming release to date. There's of course been a couple of minor versions this summer and we'll also cover them but first let's focus on the new killer features: the scheduler, alerting through slack/mail and a better UI for the menus.

The scheduler is the first item left on our original roadmap (back when OctoPerf was still called Of course we've got a lot more planned on our current roadmap than back then, but still it's an important landmark for us! We've decided to merge it with notifications through slack integration or mail so that you can get the best out of these scheduled tests.

At the same time we've worked on the menus to highlight all the possibilities instead of hiding them in sub-menus.




OctoPerf 11.9 - Azure on demand, new JMeter, setup/teardown threadgroups and more

Here we are for yet another new release of OctoPerf. We've actually released two minor versions since the last update post, but this time we will also release a long awaited feature, Microsoft Azure on demand load generators!

We kept it in our beta version for a while since we wanted to be absolutely sure it can be used for proper testing. We are quite satisfied with it at the moment, but note that the agent startup time is much longer on azure than on other providers, you should expect to wait a few more minutes if you are using it.

Of course we also have other new and exciting features to share, so let's dive into it.


Azure load generators


As stated in the introduction, you can now select Azure load generators from the locations tab of your runtime profile. This opens up a lot of new locations and will help you test your applications under even more realistic conditions than before.

Of course it comes with all the usual features like retry on agent startup failed and load generator monitoring live during the test.
