What is summary report in JMeter?

The summary report creates a table row for each differently named request in your test. This is similar to the Aggregate Report , except that it uses less memory. The thoughput is calculated from the point of view of the sampler target (e.g. the remote server in the case of HTTP samples).

What is the difference between aggregate report and summary report in JMeter?

Aggregate Report in Jmeter is one of the most essential listener. It is almost same as Summary Report except Aggregate Report gives few more parameters like, “Median”, “90% Line”, “95% Line” and “99% Line”. Before going further it’s better to have understanding of How to Record and Run Jmeter Script & Summary Report.

What is latency in JMeter summary report?

Latency. JMeter measures the latency from just before sending the request to just after the first response has been received. Thus the time includes all the processing needed to assemble the request as well as assembling the first part of the response, which in general will be longer than one byte.

What is error percentage in JMeter summary report?

Error% denotes the percent of requests with errors. 100% error means all the requests sent from JMeter have failed. You should add a Tree View Listener and then check the individual requests and responses. Such high percentage of error means that either your server is not available or all of your requests are invalid.

How do I save a summary report in JMeter?

What is 90 percentile in performance testing?

A percentile is a very useful performance testing metric that gives a measure under which a percentage of the sample is found. For example, the 90th percentile (abbreviated as p90) indicates that 90% of the sample is below that value and the rest of the values (that is, the other 10%) are above it.

What is 95th percentile in performance testing?

The 95th percentile is a number that is greater than 95% of the numbers in a given set. The reason this statistic is so useful in measuring data throughput is that it gives a very accurate picture of the maximum traffic generated on an interface. This is a standard measure used in interpreting performance data.

What is sent KB SEC in JMeter?

Sent KB/second: This defines how many Kilobytes per second are sent to the server. 90% Line: It represents that 10% of the samplers have exceeded time to reach the server. 95% Line: It represents that 5% of the samplers have exceeded time to reach the server.

What is JTL file in JMeter?

JMeter creates results of a test run as JMeter Text Logs(JTL). These are normally called JTL files, as that is the default extension − but any extension can be used. If multiple tests are run using the same output file name, then JMeter automatically appends new data at the end of the file.
