Difference between Elapsed and Latency in Jmeter's JTL file

Question

When I run a jmeter test, I get a .jtl file with the following headings:

timeStamp,elapsed,label,responseCode,responseMessage,threadName,dataType,success,failureMessage,bytes,sentBytes,grpThreads,allThreads,URL,Latency,IdleTime,Connect,"command"

I was wondering what the difference is between elapsed and Latency

Does anyone know?

I could not find an official reference/documentation for this headings online...if someone knows if and where they exist, please also do share!

Thanks

Answer 1

According to JMeter Glossary

• Latency = time to first byte
• Elapsed = time to last byte

Official documentation is available at JMeter Project page

Kind of extension to the official documentation: JMeter Wiki
