jmeter-statistics


A CLI written in node for analysing jmeter jtl files. You can pipe a csv formatted jtl file into it, and it will output a .csv with aggregated data.

Installation

``
> npm install -g jmeter-statistics
`

Usage

The following commmand will analyse the results.jtl file and produce results into a comma separated file (csv).
`
> cat results.jtl | jmeter-statistics > statistics.csv
`
The csv will contain output similar to the following
`
> cat statistics.csv

Fields

- label: the label as defined in the jmeter test
- requestCount: the total number of requests made
- meanResponseTimeMillis: the mean response time in milliseconds
- maxTime: the maximum time in milliseconds
- minTime: the maximum time in milliseconds
- errorPercentage: the percentage of requests that resulted in a non-200 response code (as a value between 0 and 1)
- apdex: the apdex score based upon a target time (T) of 500ms
- satisfied: the number of requests defined as satisfied by the apdex target time (response time <= 500ms)
- tolerating: the number of requests defined as tolerating by the apdex target time (response time <= 2s)
- frustrated: the number of requests defined as frustrated by the apdex target time (response time > 2s)
- ninetiethPercentile: the value below which 90% of the samples fall (Refere here)
