New Versions Supported: JMeter 4, Java 9, Taurus 1.10.5


Now you can run JMeter 4, Java 9 and Taurus 1.10.5 on BlazeMeter.


We will deprecate JMeter versions <2.13 in April.  When we do, we’ll execute these older scripts using the 2.13 engine.  Now is a great time to check to see if your <2.13 scripts need edits to run on 2.13.  JMeter is great at backward compatibility, but better safe than surprised :-)


Sandbox IP Address List Change


We have updated our Sandbox location to be served from the following six IP addresses.  If you have whitelisted our Sandbox location, you will want to update your whitelist to the following:



Chrome Recording Extension Upgraded


The Chrome recording extension has been upgraded:

  • Create and name Transactions as you do your recording with “Edit Transaction Labels”
  • Choose which requests to record with greater precision (i.e. top level requests + cookies, for instance)
  • Run tests as “API Functional Tests” (single VU with enhanced reporting)

CloudWatch APM data moved to the Timeline Report


CloudWatch now joins our other “inbound” APM integrations on the Timeline Report. Previously CloudWatch data appeared on a separate report tab. Enjoy the streamlined experience :-)

Overlay your own data on the Timeline Report (coming soon!)


Ever wish you could overlay your own time-series data on the BlazeMeter Timeline Report? We’ll be releasing an API soon which lets you post JSON data to overlay on any test, even in real time. Watch for an update in the next release or drop a line to if you want to get started right away.


Summary report graphs change resolution @ 5 min mark


The time-series resolution in the Summary report graphs now changes at the 5-minute mark:

  1. In the first five minutes of the test, the graphs show one-second resolution.
  2. After five minutes, the graphs switch to one-minute resolution.


Taurus Tests now configured on New Test Create Screen


Starting today, when you press the “Taurus” test create button, you’ll go to the New Test Create (NTC) screen being rolled out as part of our New Test Create Beta.  For advanced users who have been running Taurus tests on BlazeMeter for some time, you’ll be interested to hear that the default execution framework is moving from “Taurus V1” to “Taurus V4” with this update.


New Test Create (NTC) Beta Updates


We’ve been gradually rolling out a new test create workflow and underlying test execution architecture since earlier in the new year. Here’s a peek at what we’ve added in the most recent drop.  If you have questions about the beta (including requests to join the beta and try it out so you can influence our final builds), please drop us a line at


NTC: Load configuration enhancements


  1. The scrolls are “exponential” so that it is easier to configure using them.
  2. The test visualization graph now shows a “zoomed in” view of the ramp up period, with ⅔ of the space showing the ramp and ⅓ of the space showing duration of the post-ramp hold period.
  3. We added support for the “Limit RPS” setting and “Change RPS” mid-test button.

NTC: Debug Test


The Debug Test button launches a quick run of your test at low scale to confirm that everything works from the cloud. Unlike the “sandbox test” feature in the previous version, with Debug Test, your settings (such as scale, location or duration) aren’t changed or reset in any way. We also write out a more detailed “trace.jtl” log for these runs to assist with troubleshooting.

NTC: File Validation


When you upload a file in New Test Create, we validate the uploaded file, checking for:

  • Missing files that are part of configuration (referred within a yml)
  • Broken JMX (XML issues)
  • Invalid YML
  • Taurus configuration errors


The validation occurs automatically on file upload and you can re-validate on demand by clicking the “Revalidate” after making corrections/uploading new files.

New Cloud Locations: Google Montreal and Netherlands


This week we’ve added two new Google locations, Canada East (Montreal) and EU West (Netherlands). You can now choose from 56 cloud locations across Amazon, Azure and Google. 


You asked. We listened.


Sometimes it’s the little things that matter the most. This week we implemented two requests that were recently posted as feature requests on the Ideas Portal:


Resize columns in Request Stats and Executive Summary reports


Long labels truncated? Just drag the column wider to see it all.

Timeline tab settings now “sticky” within same report session


Changes made to the selected KPIs on the Timeline Report are now “sticky” within the same report viewing session.  For instance, if you switch from Timeline to Errors or Engine health and then back to Timeline, your KPI selections will remain as selected.

Time zone setting for BlazeMeter UI


Now you can easily override or “offset” your local browser timezone setting for all time/date displays in the BlazeMeter UI.  It’s also easy to toggle this feature on or off with a click.


Teams collaborating across times zones asked for this feature so they could discuss time stamps in reports without having to convert times in their heads.  We are happy to provide it!


Navigate to: Settings > Personal > Personal Settings to set or toggle Time Zone Override:
