I am setting up a test against single EC2 instance. In that EC2 it has only Django application. It has no S3/CloundFront or RDS assist it. Everything purely run on Docker and basic setup of memory and CPU.
My goal is I want to see the empirical performance of my single EC2. It will help me do roughly cost estimation on the production.
You can skip this and jump to my problem:
Here is my production setup
1 load balance
2 nodes with identical setup by using docker image
1 bucket/cloudfront
1 rds
Softwares:
django==2.0.5
djangorestframework-jwt==1.11.0
djangorestframework==3.8.2
Tools:
JMeter 4.0 r1823414
javac 10.0.1
java 10.0.1 2018-04-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.1+10)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.1+10, mixed mode)
java version "1.8.0_171" Java(TM) SE Runtime Environment (build 1.8.0_171-b11) Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode) javac 1.8.0_171
Parameters:
Thread Group
- Number of Threads: 10
- Ramp-up period: 1
- Loop Count: 1
HTTP Header Manager
- Content-Type, Application/json
- Authorization: jwt ${token}
HTTP Request
- http
- localhost
- port: 8000
- POST
- Path: /api-token-auth/
- Body data : {"username": "myname", "password": "mysecretpassword"}
At this point test is good. All are green I can have token back from Django.

I have tried this But I could not get it work. Here is my navigator bar
Debug Sampler:
Jmeter's token is empty
JMeterVariables:

Questions:
How to let jmeter grab jwt token and shoot another endpoints?
Update1:
When I disable Patch Branch. Debug Sampler does show me the token value
Update2:
I was wrongly call the variable. But PATCH problem still persist. Now I can call token. Here is my request
PATCH http://localhost:8000/api/branches/5/
PATCH data:
{
"name": "Bangkok"
}

Update3:
Problem seems to be jmeter side because. When I open the backend log.
PATCH never reach the backend

Update:4
Found the clue. It might be the problem from HTTPClient4
Update:5
Try imitate the original java8 environment. It raises the same problem
