jmeter-grpc-request's Introduction

JMeter gRPC Request

This sampler JMeter lets you send an gRPC request to a server.
It's as simple as a HTTP Request.

简体中文 | English

What is it

This is a simpler of JMeter used to test for any gRPC server, it is not necessary to generate gRPC classes or to compile the protos binary for the service. Just a very simple for input:

Host and port of gRPC service.
Method of service needs testing.
Folder path of proto files.
Data request in JSON format.

Same as JMeter HTTP Request but for gRPC. Copy only once file jar to lib/ext of JMeter, select your protobuf folder and start making requests! No extra steps.

The JMeter gRPC Request is available at JMeter Plugins Manager, we can find here https://jmeter-plugins.org/?search=jmeter-grpc-request

Features

Supports Blocking Unary Calls.
Parses proto files at runtime.
Supports plain text and TLS connections.
Supports authentication via metadata (JWT/Token).
Request data with JSON format.
Runs on Mac, Linux and build project by Maven.

Todo:

Supports TLS connections.
Supports authentication via metadata.
Auto list full methods.
Count the failed request in the report.
Auto generate request data base on proto file.
Supports grpc-web protocol (HTTP1.1).

Usage

Requirements

All you need copy jmeter-grpc-request file jar to directory lib/ext of JMeter and restart JMeter GUI (copy once, use forever). Binary are available from the Releases Page.

Making a gRPC request with JMeter

Create test script:

Add Thread Group: right-click on the Sample Test (our Test Plan) → Add → Threads (Users) → Thread Group.
Add GRPC Request: right-click on the newly created Thread Group → Add → Sampler → GRPC Request.
Fill info request: host, port, method, data request, proto folder.
Save test script.

Run test:

Via JMeter GUI: in top bar click Run → Start.
Via command line: bin/jmeter -n -t <test JMX file>.jmx -l <test JMX result>.csv -j <test log file>.log -e -o <Path to output folder>.

Configurations

No.	Fields	Description
1	Server Name or IP	Domain/IP for gRPC server
2	Port Number	Port for gRPC server (80/ 443)
3	SSL/TLS	SSL/TLS to authenticate the server
4	Disable SSL/TLS Cert Verification	Disable SSL/TLS certificate verification (enable this function when using self-signed certificates)
5	Proto Root Directory	Root directory contains proto files
6	Library Directory (Optional)	Using a different underlying library (googleapis)
7	Full Method	Full Method to test
8	Metadata	Metadata can be use for Store token, authentication method, etc. Two Ways to use metadata, 1. Comma separated Key:Value : - key1:value1,key2:value2 - Value should url encode with utf-8 2. Json String : - {"key1":"Value1", "key2":"value2"} Note: In gRPC Metadata value is (Key, value) both in format of (String, String), in case of nested Json Objects values, will go to request as a JsonString.
9	Deadline	How long gRPC clients are willing to wait for an RPC to complete
10	Send JSON Format With the Request	Data request with JSON format

Running the examples

Example invocations can be found in the example directory.

jmeter-grpc-request's Issues

Request Mock use JMeter function variable

TODO: I am not sure how big is the meaning of this feature, When I receive a clear demand, I will provide a PR for this feature.

gRPC request cut JSON fields with emty values

Hello!
Trying to use gRPC plugin for some perfomance testing on our server.
I'm trying to send some JSON with several fields for request e.g. :
{
"filterByStatus": [],
"totalsByStatus": [],
"date": "2021-07-28T00:00:00.000Z",
"offset": 0,
"limit": 12,
"sortBy": "",
"sortDirectionDesc": false,
"vName": "",
...
"lName": ""
}
this is general request to get everything for current date.
So, i've added View Results Tree sampler for debug and it show me request body as:
{
"date": "2021-07-28T00:00:00Z",
"limit": 12
}

I need send all fields, because in over case server just returns me OK. 200. instead of data set.

Could you please help me solve this problem ?

Add support for closing stream when a number of messages is received

When used with gRPC stream services, basically the client needs to close the stream when it have all the needed responses and does not plan to issue new requests.

Currently this can only be handled by the response timeout GUI option of the plugin, which actually results an error. It would be really nice if a new numeric field can be added which will close the connection when certain number of messages are received.

GRPC Request

Hi Team,

Currently we are using the Jmeter-GRPC-request sampler for the gRPC services. but we are not able to perform getting below errors, pls provide your support to overcome this issue.

Modifying User-Agent

Hi,

I am trying to pass User-agent in metadata section but it is not working.

Thanks

Add support for bytes fields

JSON doesn't natively support binary data, which makes bytes fields more or less impossible since you can't put them in the jsonRequest parameter. There's also the problem that bytes fields can be quite large, and you wouldn't really want to put binary data in the JML anyway.

We're using this sampler for a load testing project and want to support binary uploads. I have a few thoughts for how to add that support, and some time to work on it. Before starting, I wanted your thoughts and to know if you'd be accepting of contributions.

My thought is to add a parameter with a field path for the bytes field in the request, a path to a local file with the bytes to set in the field, and perhaps a starting byte offset and length for the read (to support chunking files). Does this sound reasonable?

Thanks!

In the end, I do not understand how the method is not recognized.
Do you have an idea, why ?
I'm very thankful for every help!

JMeterThread: Error while processing sampler: 'GrpcRequest'

Can you support: parses online proto files at runtime?

`metadata` value should decode.

In buildHashMetadata() method, if value has , or : char, the method will throw exception.

For example, the W3C trace header:

traceparent: 00-785ccc23896e40dcaa7fefd86bb5324a-92eb2aadf3e44c3b-01
tracestate: client-app-id=svc-basic-dps,client-ip=10.233.79.118

Current metadata string: traceparent:00-785ccc23896e40dcaa7fefd86bb5324a-92eb2aadf3e44c3b-01,tracestate:client-app-id=svc-basic-dps,client-ip=10.233.79.118. If allow encode/decode, metadata string should be: traceparent:00-785ccc23896e40dcaa7fefd86bb5324a-92eb2aadf3e44c3b-01,tracestate:client-app-id%3Dsvc-basic-dps%2Cclient-ip%3D10.233.79.118

Publish to jmeter-plugin so can be directly downloaded from jmeter plugins manager UI

This is up to the authors, but I think it would greatly increase visibility and presence if this was visible within the mainstream jmeter plugin manager download option. Currently there are no GRPC plugins, and most external plugins maintain author/etc but are added through jmeter-plugins.org

some potential steps here, most reference reviewing the group threads for the steps: https://groups.google.com/g/jmeter-plugins/c/be-vMCfPA_g/m/x4dvAq24AAAJ

Recommend updating license information, such as to pom.xml.
example: https://github.com/undera/jmeter-plugins/blob/master/plugins/perfmon/pom.xml

Support setting version of protoc

I am trying to use this plugin, but it is failing to compile the proto.

When I went through and debugged, I noticed we are using an embedded protoc library, that is older than the version that I am on.

I am on 3.15.1, which contains support for optional, where this plugin is only up to 3.11.4.

Simplest thing would be to either set the protoc version with the plugin used here, or allow usage of the system protoc version, so users can control what version they are on.

Add support to .protoset

Please add support for .protoset files

Protoset files contain binary encoded google.protobuf.FileDescriptorSet protos. To create a protoset file, invoke protoc with the *.proto files that define the service:

protoc --proto_path=.
--descriptor_set_out=myservice.protoset
--include_imports
my/custom/server/service.proto

About JMeter grpc uploading files

The interface for uploading files / pictures cannot be adjusted directly. It is easy to request success with Bloom RPC, but the direct request with JMeter grpc fails, and there is no response, or even an error. Please solve it!!

Add same license file as jmeter-grpc-plugin

Adding license file, reuse same one as jmeter-grpc-plugin: https://github.com/zalopay-oss/jmeter-grpc-plugin/blob/master/LICENSE

Where to add grpc option?

eg. grpc.ssl_target_name_override

The caller of the secure_channel_create functions may override the target name used for SSL host name checking using this channel argument which is of type GRPC_ARG_STRING. If this argument is not specified, the name used for SSL host name checking will be the target parameter (assuming that the secure channel is an SSL channel). If this parameter is specified and the underlying is not an SSL channel, it will just be ignored.

grpc.health.v1.Health proto built-in?

Hi all,
Trying this out, was excited for a way to test GRPC without pre-compiling proto into code binaries (particularly if testing grpc in a language other than jmeter's java).

Testing this, which may be a good one to include by-default (maybe a tab or radio button or pulldown): https://github.com/grpc/grpc/blob/master/src/proto/grpc/health/v1/health.proto

JSON empty caused issues (seen in the log), so added '{}' for now, but still not able to run (but no errors in log now)
port 443, checked SSL/TLS
proto root directory pointing to health.proto
library directory empty
full method: grpc.health.v1.Health/Check (from listing button and selecting, awesome!)

I am getting this error in the View Results Tree:

Response code:500
Response message:Exception: UNAVAILABLE: io exception
Channel Pipeline: [SslHandler#0, ProtocolNegotiators$ClientTlsHandler#0, WriteBufferingAndExceptionHandler#0, DefaultChannelPipeline$TailContext#0]

Using commandline grpc-health-probe (That has the health.proto built in) to same destination returns successfully (status: SERVING)

Caught exception while waiting for rpc ?

After Loaded My proto inside jmeter when I run it I this get Error :
#Response code:500

Caught exception while waiting for rpc

Use Variables in Metadata

Hey,

I was trying to set access token dynamically in the metadata but it just sends the variable name as a string.

java.lang.IllegalArgumentException: Unable to read messages from json

Hello.

I was trying to send request with json. Empty json: {} is working correct, but when I'm trying to send something more I received error on readWithJsonData() method - line 99 jsonParser.merge(jsonData, nextMessage);

How to avoid/Limit generating protocjar and descriptor.pb.bin files when sending Load?

When sending traffic below files are getting generated under tmp directory and due to this CPU utilization of the server is increasing where JMeter is running.

Also because of these protocjar9031435801376843182 directories, the disk is getting full very fast

Exporting gRPC results to InfluxDB

Hello,
Thanks for the development of the gRPC plugin, we have been using it successfully for a while.

We would like to export gRPC results to InfluxDB and visualise them in Grafana as we already do for our HTTP uServices with the help of JMeter Backend Listener.

Is it possible somehow to achieve the same for gRPC requests using your plugin?

Suggestion to add this plugin to JMeter Plugin Repository

Thanks for this great plugin. Could you please publish this in the official JMeter-Plugins repository? It will reach the masses and help in automation and containers.

Thanks!

In Metadata, what if we have comma in value.

Currently, In metadata > key1:value1,key2:value2,
And it is being split by Comma (,)
In one of my requirement i have json string as a value.

key1:value1,key2:{"k":"val","k1":{"val":"val2"}}
so, basically key2 is a JsonString, which have comma inside string,
It is giving Error.

Is it possible to support JSON String as Metadata as we do in BloomRPC?

JSON response: camelCase vs field_name

Which is it supposed to be:

myField

my_field

I just re-installed my jMeter and gRPC plug-in and it seems to have changed.

Variable values not getting replaced in Metadata filed of GRPC request

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

Enhancement request: Add grpc reflection support

jmeter-grpc-request is a very nice tool, and here's an enhancement request. For services that support grpc reflection, it would be a big logistics issue to copy around proto files from many microservices to the load testing server. Although it isn't uncommon for tools to require the protos there are some tools that take advantage of grpc reflection (like grpc-client-cli command-line tool). It would be really scalable to support grpc reflection, and granted not every service enables reflection but some organizations can and do enforce that requirement.

The idea would be there would be a check-box "Use grpc reflection" and the proto field would grey out.

gRPC - Library Directory (optional)

Could you pls share the gRPC-Library Directory --> Default files.

Thanks,
SRV

This is a problem with a long history of windows. If we want to solve it, we may need to replace the protoc-jar-maven-plugin dependency in maven pom.xml.

I am trying a solution that does not replace.

Cannot send requests via secure connection

Hi,

I am trying to use this plugin to send a GRPC request via Jmeter. I have imported the trusted keys into my Jmeter key store and can see them loading in the debug output - however whenever I try and run the request I see the following error.

DEBUG i.n.h.s.ReferenceCountedOpenSslEngine: SSL_read failed with 1: OpenSSL error: 268436496 error:10000410:SSL routines:OPENSSL_internal:SSLV3_ALERT_HANDSHAKE_FAILURE

The same GRPC request works in a standalone application using the same keys used to send single requests. I only seem to have this error while sending requests from this plug in.

Do you have any suggestions on the cause of this issue ? Do I need to import certificates a different way compared to normal Jmeter certificate locations ?

gRPC failure count not counted in the listener (Aggregated Report , View Result tree......)

One more update required,

if any failure happened in the gRPC current sampler then the failure count is not counted in the Aggregated Report. if you incorporate the changes along with jar. really it be useful for all the people.

Thanks in advance.

Eagerly waiting for the updates
