I am running a load test on JMeter with 200 users. Around 10 percent of the request sent for each sampler results into failure with a status code 404 - Not found error. However, if I run my test with a load of 100 users I do not encounter 404 errors. Please advice me on what can be the issue and possible solution for this.?
It’s a server issue only. Some applications handle server error in a kind of strange way.
So you would need to:
analyze access logs
add monitoring and APM to diagnose
check error logs

my logs on a publicly accessible server are bloated with this error
Error 2022-10-11 22:11:50 staging [0] "" on line 44 of file /var/www/html/vendor/laravel/framework/src/Illuminate/Routing/AbstractRouteCollection.php
that line just throws a \Symfony\Component\HttpKernel\Exception\NotFoundHttpException, a 404 basically.
I suspect the huge amount is due to the attempts at hacking the webserver (reflected from the apache access logs.
First of all, can I add the info about the url that's failing?
Then, can anyone suggest a way to deal with this to reduce the amount of errors (even because I use a monitoring app and get charged on this events)?
Thanks
Getting 500 error post deploying microservices on app service on the Azure
I ran across this same error today, for me the source of the problem occurred during startup. My application was trying to create a file, and this is not allowed.
"Running from package makes wwwroot read-only, so you will receive an error when writing files to this directory."
Source:
https://learn.microsoft.com/en-us/azure/app-service/deploy-run-package
Generally 500 comes due to application error on the server.
When "Server Error in '/' Application" comes , did you observe anything in "Diagnose and Solve Problem" under 5xx errors.
3) You can enable FREB logs . Follow this blog how to do it https://blogs.msdn.microsoft.com/benjaminperkins/2017/01/27/enable-failed-reuqest-tracing-for-an-azure-app-service-web-app/

I have setup a load test rig with a Client (VS 2013 Update 5), Test Controller and 5 Test Agents. For testing the working of this environment, I have configured load test to run just for 5 users (Step based).
At the end of load test, the Visual Studio is displaying the error message
"Could not read result repository: Unknown request id in results:185"
I have checked if the agents are running out of CPU, RAM etc. Even I have enabled logs on Test Controller, Agents but found no clue or error message.
However I found that the error is occurring due to missing records in the table WebLoadTestRequestMap of LoadTest2010 database.
I have set the value none to the option Timing Details Storage and found that this issue is not occurring. When I set this value to All Individual Details, the error is occurring again.
I don't know what's causing this error. Can anyone help me fixing this error?
I am new to JMeter. I did my first script in JMeter.
My scenario is: clicking a button, i.e. after login, click that button. Thats it. Upto this i have recorded for my script using JMeter.
When i run for single user, it gives proper output for any different user. But when i run with concurrent users (2 or more users with User Parameters pre-processor), it shows error in clicking that button.
I have used View Results Tree as listener to see the results.
In sometimes, it does not show error. So i can't identify the exact reason, why it fails.
Can you please anyone can guide me regarding this?
I am completely new to this JMeter.
Thanks in Advance,
A 500 internal server error indicates jmeter is making the connection to your server and your server is having difficulty processing the request. You should probably look at your server log files to see if there are any errors or exceptions (apache/jetty/etc log file).
Additionally, when you DO actually have an issue with jmeter and you can't seem to figure out what is going on from your listener output, you can view the jmeter.log file created in the directory when jmeter is run from. This usually gives more detailed information regarding failures in jmeter.
To check the status of database servers, I use tnsping utility.
Is there any similar utility for checking reports server?
Thanks.
Without access to the ReportServer admin console, that can be tough. But a call to /reports/rwservlet/showjobs?server= might do the trick for you. If you get a response, it confirms the server is up and running, and it'll show you any jobs that are running.
I've also implemented a procedure in the past that periodically runs a minimal report using utl_http and looks for a reasonable response. Then emails if it timesout or gets an HTTP error or report server error.
I would agree with Jim Hudson, the Oracle Application Server Control is the easiest method to monitor your Oracle Report server(s).
However you can gain some information about the status from running the following command:
http://hostname.domain:port/reports/rwservlet/getserverinfo?server=yourReportServerName
