How to generate Report Dashboard in JMeter

Steps to Create Report Dashboard in JMeter

1) Create a JMeter(.jmx) file as per the requirement , if it has large number of users ,then go for Non GUI Mode as discussed in the previous post ,otherwise run it from the JMeter GUI Mode Itself.
2) While Creating add a Listeners in the JMX File.
3) After completing the Load / Performance Test , go to the Listeners and Save the data as .csv file , if the Load / Performance Test is done from the GUI Mode.
4) If it is ran from the Non GUI Mode , then open the same JMX File in JMeter and Add Listeners in that.
5) Then Browse the JTL from the Listeners and the data will be shown in the JMeter.
6) Save that as .csv File by clicking "Save Table Data".
7) Then open reportgenerator.properties from JMeter > Bin Folder , Copy all the content from the properties file.
8) Open user.properties from the same path as mentioned above and Paste all the content and then "Save".
9) Now run the below mentioned command in the command prompt.
10) jmeter -g "Path of .csv file" -o "Path for Reports"(Dont Create as "ReportD"),
as it will be automatically created from JMeter itself ).
11) Finally Reports will be generated in the "Path for Reports/ReportD".

How to Solve "Out of Memory Error" in JMeter

                

There are 2 ways to solve this issue

1) Increasing Heap Size.

2) Running JMeter in Non GUI Mode.

How to increase Heap Size in JMeter

1) Open jmeter.bat File(JMeter > Bin ), Search for "Heap" in the File.

2) You will be finding some thing as "HEAP=-Xms512m -Xmx512m".

3) In this , change the second part as -Xmx1024m(Depends on your system RAM,can be given upto 80% of the RAM Size).

4) Then start JMeter by double clicking the jmeter.bat file .

Running JMeter in Non GUI Mode

1) Before running JMeter in Non GUI Mode , Make sure you have not added any "Samplers" in JMeter

2) Do all the stuffs in JMeter to do Load / Performance Testing , Such as Recording HTTP Requests, Threads(Users) as per the requirement .

3) Save the JMeter File in JMeter > Bin Folder  .

4) Open the Command Prompt and Navigate to JMeter > Bin Folder

5) Then type the command as "jmeter -n -t YourFile.jmx -l YourFile.jtl"

Where, -n indicates Non GUI Mode

             -t indicates JMX File

            -l indicates Log File(JTL File)

Basic Elements required to do Load/Performance Testing in JMeter

                    

Below mentioned elements are required for JMeter Basic Load / Performance Testing.

1) Test Plan

2) Threads Group > Recordings

3) Workbench > Http(s) Test Script Recorder

4) Basic Listeners

1) View Result Tree

2) Summary Report

Here Test Plan and Workbench will be Shown when the JMeter is freshly opened (Open JMeter using jmeter.bat for Windows in JMeter > Bin Folder) and (for Linux jmeter.sh).

User can add above mentioned elements manually one by one (or) Click the "Templates" which is located in the Menu Bar,Which will create all Basic Elements of JMeter to do Load / Performance   Testing.

Test Plan : A test plan is the top level body of JMeter, explains sequence of steps execute at run  time.
