In the NBomber v6.2.0 release, we focused primarily on improvements to cluster mode, and we also introduced several useful enhancements to the HTML Report.

• HTML Report improvements
• NBomber Cluster improvements
• OpenTelemetry Reporting Sink
• What's next

HTML Report improvements​

One of the invisible but important changes in the new HTML Report is that it has been completely rewritten in TypeScript. For a long time, we used vanilla JavaScript with Vue, but over time it became difficult to manage complexity, reason about the code, and maintain correctness. Moving to TypeScript gives us type safety and makes future development more sustainable.

Now, let’s look at the visible improvements 🙂

Status code chart colors​

Previously, the colors for the status code chart were automatically selected by the charting library. This made it difficult to clearly distinguish successful responses from errors. In this release, we fixed that by introducing two distinct color groups—green for successful responses and red for errors—with slightly different shades.

This change significantly improves the clarity and readability of the status code chart.

In the new release, we are introducing Custom Metrics, one of the most requested features. Additionally, we've made several improvements related to thresholds, memory consumption, CSV, HTML reports, and more.

Custom Metrics​

In the new release, we ship a few big features:

• Scenario Weight
• Native extensions for probability distributions
• Runtime Thresholds

Scenario Weight​

In the new release, we focused on TimescaleDB support and web browser testing capabilities. Some of our customers use PostgreSQL to store various data, so adding PostgreSQL support through the Timescale extension was a logical step for us. Additionally, we are developing NBomber.Cloud and use Timescale to store and query our metrics.

NBomber​

• Scheduler timer calibration
• Fixed stopping process for scenarios
• Add API method NBomberRunner.EnableStopTestForcibly
• Fixed. Incorrect handling of stop scenarios earlier blocks the console
• Fixed. Under the high load the console timer is desynchronize
• Added Log.CloseAndFlush
• Refactored functionality to stop Scenario actors
• Refactored measuring time to use time buckets
• Changed the default ReportingInterval to 5 sec
• Adapted NBomber for int64 changes in NBomber.Contracts

Hey folks, we were busy for nearly half a year working on a new big release of NBomber. I am so happy to announce that we finally completed it!

In this release, we focused on improving engine performance, fixing RAM consumption issues, improving UI/UX, including reporting, extending API to provide flexibility but keep it SIMPLE as before.
