Exception generated when trying to generate jmeter HTML reports

You have a typo in your command, change it to look like:

jmeter -Jjmeter.save.saveservice.output_format=csv -Jjmeter.reportgenerator.apdex_satisfied_threshold=1500 -n -t D:\jmeter\v1_images_scenario.jmx -l D:\jmeter\images.jtl -e -o D:\jmeter\Reports\

i.e. change statisfied to satisfied

Going forward check the following files:

• reportgenerator.properties
• user.properties
• jmeter.properties

For the following line:

jmeter.reportgenerator.apdex_satisfied_threshold=${jmeter.reportgenerator.apdex_satisfied_threshold}

and once found - delete or remove it, this way you will be able to generate the dashboard using default threshold of 500 if you don't override the property.

• Apache JMeter Properties Customization Guide

Although the accepted answer resolved the OP's issue, I thought I would add an additional answer here as I ran in to this same behaviour and was unable to find a quick answer, thus wasting a lot of time searching, digging and the like.

In my scenario I had, mistakenly, changed from using -q <properties file> to -p <properties file>. What I didn't realize (at the time) is -q defines an additional properties file to be read, whereas -p overrides the jmeter.properties file. Thus when using -p I was missing properties that were required to correctly generate the dashboard. Incidentally, the "Summariser" (logger that periodically writes statistics to stdout) also stopped working, so that was an additional side effect. Interestingly my tests weren't failing, just the dashboard creation error and the missing Summariser.

Looking at the official documentation: https://jmeter.apache.org/usermanual/get-started.html#options this distinction is made, but other sites out there aren't so clear on that matter. So there you go...
