How to send message to Azure event hub with amqp using JMeter.
can anyone please help in this regard.
Download azure-messaging-eventhubs library and all its dependencies and drop them to JMeter Classpath
Restart JMeter to pick the libraries up
Add JSR223 Sampler to your Thread group
Write Java (or even better Groovy) code implementing your scenario in the JSR223 Sampler. Example code can be found at Use Java to send events to or receive events from Azure Event Hubs (azure-messaging-eventhubs) article, I'll add it here just in case:
import com.azure.messaging.eventhubs.*
final String connectionString = 'EVENT HUBS NAMESPACE CONNECTION STRING'
final String eventHubName = 'EVENT HUB NAME'
// create a producer using the namespace connection string and event hub name
EventHubProducerClient producer = new EventHubClientBuilder()
.connectionString(connectionString, eventHubName)
.buildProducerClient()
// prepare a batch of events to send to the event hub
EventDataBatch batch = producer.createBatch()
batch.tryAdd(new EventData('First event'))
batch.tryAdd(new EventData('Second event'))
batch.tryAdd(new EventData('Third event'))
batch.tryAdd(new EventData('Fourth event'))
batch.tryAdd(new EventData('Fifth event'))
// send the batch of events to the event hub
producer.send(batch)
// close the producer
producer.close()

I have a doubt, in a group chat system that has a database with a rest API, who should issue the event of a new message?
The client or the endpoint to create the new message?
For example: X user sends a message to group Y, then uses the api endpoint api.com/message-create and that endpoint emits the message-create event through websocket
Example 2: X user sends a message to group Y, then uses the api api.com/message-create endpoint and the endpoint does not emit the message-create event, but was emitted when the user pressed the send message button
I still don't quite understand if it would occupy more websocket channels to achieve that, if a global one is enough, etc.
The server should be responsible for communication logic. So your first example is better.
But: why do you use two communication channels for sending an creating messages?
If you use websocket, you don't need create a message from a client by using additional rest endpoint.
This approach is prone to errors. For example if the client will loose network connection after sending message through websocket and before executing call to the REST endpoint?
The message will not be stored in a database.
Your flow should looks as follows:
User clicks the send button.
Message is send through the websocket.
Message is stored in the database asynchronously (you can do it directly from communication server, or use rest endpoint)
Emit "new message" event to the group.
I am facing an issue while attaching a file in my SMTP sampler.
Below are the steps performed:
1-Writing the Summary Report results into a file/folder i.e D:/ABC/XYZ${__time(ddMMyyhhmmss)}.csv (It successfully write on that path)
2-Attaching the same file i.e D:/ABC/XYZ${__time(ddMMyyhhmmss)}.csv in my SMTP sampler against Attach file(s) field.
Now I Execute my Script and got this error.
Response code:500 Response message: IOException while sending message
And after that, when I don't attach any file. My script runs successfully.
One more thing I want to add. Earlier to this script, I was able to send the attachments too but those were from my Gmail account added in SMTP. And now I am doing it from my company's email account i.e. using outlook in SMPT sampler.
Please guide me in resolving the said issue.
Your ${__time(ddMMyyhhmmss)} will generate different results each second:
so you most probably need to amend:
first usage as ${__time(ddMMyyhhmmss,timestamp)}, this way the first function call will store the generated value into timestamp JMeter Variable
second, third, etc. as ${timestamp}
Outlook is an application which can access multiple mailboxes using various protocols like SMTP, POP, IMAP or Microsoft Exchange. JMeter supports first 3, but if your company is using MS Exchange as email transport - you won't be able to use SMTP Sampler, you will have to switch to JSR223 Sampler and write your mail sending code in Groovy using library like javaxt-exchange or EWS Java API
I have an application which uses IBM MQ to send out the request in a queue manager to a particular system B.
The response corresponding to that request is then received back from system B by the application in a sync call and then further business processing happens.
Since we are working on the offshore region, we do not actually send out the request to system B but rather capture it ourselves using the MQJExplorer tool and send back the response, which kind of simulates the prod. behaviour.
The problem here is, or i would say, the overhead is that we have to manually open the mqjexplorer tool, check the request, take a particular attribute from the request(lets say ID), and send back ID+1 so that the application recognizes the response is for ID-1 request.
I would like to know if this particular thing can be automated, with some other tool, where i can define like whenever any such kind of request is received in for eg: MQ001 queue manager and its REQ queue, just extract the ID attribute, do a ID+1 and send back the response in RESP queue of same qm.
There are a pair of IBM supplied samples that come with IBM MQ:-
amqsreq0.c - Sample C program that puts request messages to a message queue and shows the replies (example using REPLY queue)
amqsecha.c - Sample C program - echo messages to reply to queue
They are supplied to allow you to try out a request/reply application.
You already have the equivalent app to do the job that amqsreq0.c does, and you could adapt amqsecha.c to extract your ID attribute, increment it, and then the sample already has the code to send the reply back.
It can be automated by running as a triggered application too.
If 'C' language is not your thing and prefer Java then have a read of a blog posting I did in 2017. It is a complete request/reply scenario with 2 applications: BEServer01.java and RQClient01.java
You can modify BEServer01.java to your liking (and remove the SQL code). BEServer01.java contains all of the code for getting a request message and sending a reply message. Simply replace the variable 'replyText' contents with the reply message that you want.
If you are not a programmer then there is another option but it does not modify the message contents. MQ Visual Edit has a component called: SIM Server. Its purpose is to simulate a server-side component. You configure what 'request' queue to get the messages from and what the reply message text will be. When a messages lands on the request queue, the SIM Server will retrieve it and send the reply message to the queue & queue manager specified in the MQMD's ReplyToQueueName and ReplyToQueueManagerName fields.
I am new to Twilio. We have a requirement in the project as follow -
Send an outbound SMS to a given number. The message body is static text and should be defined using a template on Twilio(TwiML), so that client can change the message body anytime without making any changes in the backend application.
I have gone through the Twilio documentation to understand how to use TwiML, but couldn't find any document or article which explains how to use TwiML for sending an outbound SMS. Currently I am using following code to send a SMS and the message is configured in the Spring Boot application.properties file.
Message message = Message.creator(new PhoneNumber(phoneNumber),
new PhoneNumber(fromPhoneNumber),
messageBody).setStatusCallback(URI.create(callBackUrl)).create();
Does anyone know how to use TwiML template to send an outbound SMS. Can someone help me to solve this problem. Thank you.
What is Twiml?
Twiml is instructions for Twilio, how to respond to an incoming phone call,SMS, etc...
What is Twiml
It is not for outbound actions.
To initiate an SMS , you should use the Twilio api which is what you are doing when you use the sdk such as Message.creator
I am trying to message or send alert in Xmatters using API in postman. This call was successful and an Id also generated in response, but the message was not reached to the Targeted person.When I did it from UI the mail was sent to the targeted person.
What was the endpoint of your API? Were you targeting an inbound integration endpoint (api/integration/functions/UUID/triggers), or the form endpoint (/reapi/yyy-mm-ddd/forms/UUID/triggers)? If you target the inbound integration endpoint, you will get a UUID returned while the form endpoint will return an event ID.
If an event was created, you will see an entry in the reports tab of the UI for that event and it will have any errors around notifying users.
