Http Status code =404 [Not Found] for "Http:\\myapplication.bluemix.net\loginservlet" on Load runner

We want to put a load of 500 users , Initial when we run 10 concurrent user the result is passed by 10/10 but when we run more than 10 it crashes out and it display the below mention issue.

Http Status code =404 [Not Found] for "Http:\\myapplication.bluemix.net\loginservlet"

For save side we increase below mention in Runtime-settings -> Preference -> Options.

1- Http connection timeout (sec) 120 to 240 sec

2- http-request receive timeout 120 to 240 sec

3- Step time out caused by resources is a warning 'YES''

 

Please anyone know the solution.

Re: Http Status code =404 [Not Found] for "Http:\\myapplication.bluemix.net\loginservlet"

Hi, this sounds like you are runing two different load tests.

1) 10 vu, the result is everything goes well
2) 500 vu, the result is all or parts of the system under test resports errors, stops responding as expected, and so on

May I ask about what methodology you are using, how it looks? What is your method to identify load levels your system can cope with, how to do go forward to see WHEN things go bad and at that point to identify WHAT went bad?

Re: Http Status code =404 [Not Found] for "Http:\\myapplication.bluemix.net\loginservlet"

Thanks Zeuge,

We want to execute below mention load levels in our application in order to get the response time accorrding to levels.

1- 10 Vusers

2- 20 Vusers

3- 50 Vusers

4- 100 Vusers

5- 500 Vusers

First we put 10 Vuser load concurrently on the application and get the response of time around 1 . 583 seconds with successfully 10 Vuser result.

In the Second senarios, We put the load of 20 Vusers concurrently, It show the result of 16 Vusers successfully and 4 failed Vuser with below mention error.

Status code =404 [Not Found] for "Http:\\my​applicatio​n.bluemix.​net\logins​ervlet"

In the Third senarios, We put the load of 50 Vusers concurrently, It show the result of 22 Vusers successfully and 28 failed Vuser with below mention error.

Please describe me the detail of above mention issues, Is it Load runner configuration and Scripting issue or the application is getting crashed on 20 Vuser Load.

But application is working properly when we directly hit from browser.

Hi

A HTTP 404 errormessage comes from the server.  This means that the communication between the vusers and System under test is working and the error should not be due to that fact that LoadRunner is used.

 

This means that the you need to examine the server logs, if there is anything there. You should also investigate how many open connections the server is capable to have.

 

One other thing to consider is how the vusers is started. Are all started at the same time or ar they ramped up, some (5) at the time with some delay in between. Starting all at the same is not representing real users very good, if you are not simulating users triggerd by clock like scripts. But even if you are starting all at the same time, 16 or 22 users before getting errors seems low.

Hi Umair, I agree with Ola.

As I see it, you ramp up up your load in big chunks. For the first few chunks (maybe onl one) everything is good. Later, as you increase load, you start to see how the system you test is starting to report errors.

This is expected to happen if you manage to inscrease the load high enough.

When it happens, and also before, you have to make sure you know what the logs (and possibly counters and metrics) say.

If these are your first load tests for this system, you might be surprised at the low level of the capacity the system has - so maybe you have something badly configured, something which is more developer friendly and less production like?
