I have set read and write timeouts to 5 seconds. But I have handler responsible to add data from excel which takes more than 5 seconds to complete the request.
So what I want to do is change or increase the read/write timeout by X amount of time if the request is not completed within 5 seconds.
I have implemented TimeoutHandler provided by net/http package to cancel the request if it is not completed within specified time.
What are the ways to do this? How can I manipulate the timeout?

I have to run a script for examination centre.
So the requirement is that the image APIs should hit after 30 seconds of time interval.
I have added loop controller, in that I have added a timer of 30 seconds.
But the problem is the image APIs response time is > 1 and we want to run next API after 30 seconds but currently next loop is executing after getting response from first API i.e 60 seconds
So is there a way that next API will hit after 30 seconds even if response of first API has not come yet?

If you don't care about response times and other metrics you can just set the response timeout to 1000 ms under Advanced tab of the HTTP Request sampler (or even better HTTP Request Defaults, this way the setting will be propagated to all HTTP Request samplers in the HTTP Request Defaults scope)
I have a http request. https://server:port//get_somthing?x=10.
Assume that it is expected to respond within 1 second. I notice this in newrelic that, sometimes it takes 1.5, 2 seconds. I would like to look into the logs and investigate whenever it takes more time than 1 second. So I want to set up alerts on a slack channel whenever request takes more time than the prescribed time.
How to achieve this?? I am using newrelic's java agent.
By using jmeter, I have 2 task which is :
To perform concurrent user load & to see what are the optimum concurrent transactions at any one time for 10,100,300 concurrent user.
From each of above, 1ms of data load, 2ms of data load, 3ms of data load
for both, did i just use Synchronizing Timer? what i understand is in Synchronizing Timer, Item (1) is number of simulated user to group by and Item (2) is timeout in ms. Please correct me if Im wrong..
Your understanding of the Synchronizing Timer is a little bit wrong.
Timeout in milliseconds is not the maximum response time, it's the maximum time, JMeter will wait for the Number of Simultaneous Users to Group by.
For example you defined 100 threads and one thread fails somewhere prior to the Synchronizing Timer and gets shut down - the Synchronizing Timer will wait forever hence your test will never end.
So if you want to set maximum response time threshold so JMeter will automatically mark sampler as failed if the response time exceeds maximum acceptable value - you can do it in 2 ways:
Define Response Timeout under "Advanced" tab of the HTTP Request Defaults
Define maximum response time using Duration Assertion
In both cases you will have conditionally failed response in case if response time exceeds i.e. 3 ms
What is the behavior of read and write timeouts in OkHttp?
Is the timeout exception triggered when the whole request exceeds the timeout duration or is when the socket doesn't receive (read) or send (write) any packet for this duration.
I think is the second behavior but could someone clarify this?
Thanks in advance.
The timeouts are triggered when you block for too long. On read that occurs if the server doesn't send you response data. On write it occurs if the server doesn't read the request you sent. Or if the network makes it seem like that's what's happening!
Timeouts are continuous: if the timeout is 3 seconds and the response is 5 bytes, an extreme case might succeed in 15 seconds just as long as the server sends something every 3 seconds. In other words, the timeout is reset after ever successful I/O.
Okio’s Timeout class also offers a deadline abstraction that is concerned with the total time spent.
I have a jmeter test with about 50 users. the beginning of the test performs a login and some set up stuff. I don't want this all to happen at the same time as there would be way too much contention for a part of the test I am not interested in. So I have a ramp up period of 10 seconds. There is then one specific HTTP request where I want the 50 users sending over 1 second interval i.e. a HTTP request every 20 ms. This is to ensure the 50 users are excuting this part concurrently. Ideally, something like a thread.join() after the login / ramp up would help out here, followed by another guassian timer.
Is there something similar to thread.join() in jmeter?
To mimic thread.join you can use a Synchronising Timer, this will block n threads until they reach a point and then execute them all at the same time.
If you want this request load of 1 every 20ms to continue (rather than a single burst) then you can use a Constant Throughput Controller to define the actual rate of requests you want JMeter to run. You can configure each thread to run at a rate of 60 requests per minute and this will give you one hit every 20ms (based on 50 threads with response times always less than 1 second). You can also tell JMeter to just make sure your load is 1/20ms no matter how many threads you use and it will dynamically adjust. This option is perhaps more useful in the context of load testing.
Note. When using a CTT controller, you would probably want to put the login request either in a Once Only COntroller or in a setup thread group.
