Modify current env variable HEAP="-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m" in the jmeter batch file

[Abhishek Mangudkar]

While executing taurus in gui mode, getting below message :

ERROR: JMeter STDOUT:

============================================================

Don't use GUI mode for load testing !, only for Test creation and Test debugging.

For load testing, use NON GUI Mode:

   jmeter -n -t [jmx file] -l [results file] -e -o [Path to web report folder]

& increase Java Heap to meet your test requirements:

   Modify current env variable HEAP="-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m" in the jmeter batch file

How to fix this..?

Jmeter GUI isn't opening.

[grey....@gmail.com]

That message is just jmeter gui mode output and shouldn't to be fixed.

If Jmeter doesn't start with taurus:

1. try to run jmeter from command line with/without generated jmx (<artifacts_dir>/modified_requests.jmx)

2. check jmeter.[err/log/out] from artifacts_dir. If the problem will be still vague please share these files.

1. Go to the bin folder of JMeter
   apache-jmeter-<version> -> bin
2. Right-click and open jmeter.bat file in notepad or notepad++
3. Search for the keyword ‘set Heap’
4. You can see the default heap size (1 GB – may vary in your JMeter version)
   set HEAP=-Xms1g -Xmx1g -XX:MaxMetaspaceSize=256m
5. Change the -Xms (initial heap size) and -Xmx (maximum heap size) values. You can increase these values up to 80% of total heap. In my case, I just increased the max heap size value. Refer to the below arguments:
   set HEAP=-Xms1g -Xmx2g -XX:MaxMetaspaceSize=256m
6. To check the total allocated heap to JVM, run the below command in the command prompt:
   java -XX:+PrintFlagsFinal -version | findstr /i “HeapSize PermSize ThreadStackSize”
