Jmeter : Number of active threads

Question

• I am using jmeter in elemetery freya (14.04)
• I have a jmeter test plan with view results tree
• I am trying to generate a csv file in view results tree including the number of active threads field.

• It appears to me that the detail is being entered in the result.csv file, but the values representing this attribute has no field name, and hence that detail cannot be used in a graph which I want to create from the result.csv

• I have changed JMETER-INSTALL-DIR/bin/jmeter.properties according to https://jmeter-plugins.org/wiki/PluginInstall/#Configure-JMeter

• How can I get a result.csv file with a suitable fieldname like "active-threads"

1. Don't change anything in jmeter.properties file, upgrade to new JMeter version will discard your changes. Use user.properties file instead

2. The in order to add column names to CSV file add the following property to user.properties file:

   jmeter.save.saveservice.print_field_names=true 
   

Assuming good configuration you should be seeing grpThreads and allThreads columns along with the values.

See Apache JMeter Properties Customization Guide for more information on JMeter properties and ways of working with them
