Use Variables in Metadata about jmeter-grpc-request HOT 12 CLOSED

Yes we are also facing the same issue

from jmeter-grpc-request.

@Karthicsrv you can use property values to set the metadata dynamically

from jmeter-grpc-request.

When I tried to add Metadata, I got:
Response code: 500
Response message: Exception: UNKNOWN

I'm not sure if I put the wrong format, do you have a working example for metadata here? thx

from jmeter-grpc-request.

Hi @blindchaser,

You can try again with format key1:value1,key2:value2 of metadata.
Everything will be fine.

HI @huynhminhtan
I am also facing issue with metadata, I have already tried with several format but still it is not working and shows issue

Response code: 500
Response message: Exception: UNKNOWN

Below format I have tried with but none of them works for me. Please share format with example

authorization : h7Zd4eIXQ/BKiL9v5M/aY4JFfPp
"authorization" : "h7Zd4eIXQ/BKiL9v5M/aY4JFfPp"
{"authorization" : "h7Zd4eIXQ/BKiL9v5M/aY4JFfPp"}

Hi @NateTsg @huynhminhtan

I am trying to pass variable value in GRPC metadata from CSV but its passing like ${varibaleName}. Its not replacing the string with actual value in csv.
Can you please provide your input on this

from jmeter-grpc-request.

@Ankit7327 I couldn't pass the variable it doesn't replace the variable .I used property in the form of

access_token:${_groovy(props.get("token" + ${__threadNum}))}

I iterate through the CSV and store it on the props using props.set("key", "value") then retrieve the value as shown above

from jmeter-grpc-request.

@NateTsg I tried as you suggested but its partially working in my case.
I am able to replace values in meta data but if I execute it for multiple iteration it takes the same value. Values in metadata not changing as per the thread
Can you please share any snippet or code for storing values in pros by iterating csv?

from jmeter-grpc-request.

@Ankit7327 Am store each variable with a separate thread key as follows so when you read the variable you get a different one for each thread

props.put("token_"+Thread.currentThread().getName().split("-")[1],vars.get("token"));

I store it on the props with a different thread number and get it with the thread number in the following code
access_token:${_groovy(props.get("token" + ${__threadNum}))}

from jmeter-grpc-request.

@NateTsg which sampler you have used for above code?

from jmeter-grpc-request.

@NateTsg @huynhminhtan
Query 1:-
I tried above solution, it worked properly with single iteration but while executing under load jmeter replacing blank values in parameter. Have you face this issue?
Query2:-
I tried to execute multiple request at a time. When I click on play button green dot appeared on upper right corner but users were not ramping up. There is only 1 second of ramp up is defined and test was schedule for 15 min.

Please help on this
