But i am unable to understand clearly

Can anyone help to know how to understand the error or failure of system.

Answer 1

You can use listener to understand the Logs.

Please refer below steps

1. Right click "thread group” add -> listener -> aggregate report

2. Now select your Access Log Sampler

3. Enter the IP Address or hostname

4. Enter the port

5. If you want to download the images, set "Parse images" to true

6. Select a file for "log file location"

7. Select the aggregate report

8. Enter "results.jtl" for filename

9. Now you can run the script and get the logs explained in the aggregate report.

Note : You can use different reports instead of the aggregate report depending on your requirement.

Answer 2

You can configure jmeter to add an header line with the column names by modifying the jmeter.save.saveservice.print_field_names to true in the jmeter.properties file.

By default, the columns are:

timeStamp        - unix timestamp of the request
elapsed          - time elapsed
label            - a label (page title or url)
responseCode     - http response code
responseMessage  - http response message
threadName       - name of the jave thread that did the request
dataType         - mime type of the response
success          - boolean, true if request successful
bytes            - size of the response body
Latency          - latency in ms
