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

Does this answer your question? [JMeter - Response time has same value as latency](https://stackoverflow.com/questions/56641019/jmeter-response-time-has-same-value-as-latency) — Ori Marko, Sep 24 '20 at 12:20

According to JMeter Glossary

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

Official documentation is available at JMeter Project page
