load-test | A load-test script & container for Sock Shop | Continuous Deployment library

I want to include some JAR files in my Docker image. I'm using the fabric8 maven plugin's inline assembly feature.

Here is a the dependency in the POM:

I want to define two constant labels with two static values , I refered official blog, https://blog.freshtracks.io/load-testing-prometheus-metric-ingestion-5b878711711c

Also using help, docker run quay.io/freshtracks.io/avalanche --help

I got to know that it's like below , but I tried with several combinations of it but I'm not sure how to define it.

I would like to load-test a SignalR service using Locust. I found that the following library can send and receive SignalR requests: https://pypi.org/project/signalrcore/

Now, according to the Locust docs, the next step would be to write a custom client for Locust that can send SignalR requests. But there is the following warning:

Any protocol libraries that you use must be gevent-friendly (use the Python socket module or some other standard library function like subprocess), or your calls are likely to block the whole Locust/Python process.

Some C libraries cannot be monkey patched by gevent, but allow for other workarounds. For example, if you want to use psycopg2 to performance test PostgreSQL, you can use psycogreen

I am a beginner in Python so I don't understand exactly what it means. The library "signalrcore" I am using is 100% synchronous. Does it means I can't use it with Locust? I found an a fork of signalrcore that uses asyncio. Should I use that fork instead and just make sure all my signalr calls are non blocking?

Thanks!

I'm working to optimise Largest Contentful Paint (LCP), but am having trouble preloading the correct amount of LCP candidate images based on device size.

The problem:

• on small screens, a single image shows in a carousel
• on larger screens, up to four images can show
• I don't have control of the size of said images, meaning any can be a LCP candidate
• loading all four images on small devices is a no go: a waste of bandwidth and a performance hit

The desired solution:

• preload only one image on small screens
• preload all four images on large devices

My first thought was the obvious one, use the link els' media attribute to decide what to load; however, all resources are downloaded anyway (refs 1, 2).

I'm not a fan of my current best 'solution' for this: using link's imagesrcset + imagesizes attributes to load the first image regardless, and the latter images as 1px by 1px on small devices.

E.G.

I'm looking for the best solution to execute a load test to simulate 200k - 500k concurrent users to test the web app. Some scenarios have to do with video viewing, user content pushing (like pictures, video uploading), page viewing. One of the goals is just to make sure that CDN service can handle such a huge load from the user perspective.

From the research, it seems the Jmeter can be distributed as described here:

• docker https://hub.docker.com/r/thothbot/jmeter-master/
• AWS + docker https://dragoscampean.medium.com/how-to-build-a-distributed-load-testing-infrastructure-with-aws-docker-and-jmeter-accf3c2aa3a3

Questions:

1. But, how to estimate how many slave nodes will be needed and with which hardware when looking for the cloud?

2. What about BlazeMeter service? It looks like this service can save time - just avoid infrastructure setups.

Actually, without an answer to question 1, it's not possible to calculate the cost and compare.

Any suggestion? The idea to make the target test in a strict time frame, using the best smart solution :)

I have the following Kuzzle S3 Plugin config:

I'm using PerfMon JMeter Plugin after referring this article https://www.blazemeter.com/blog/how-monitor-your-server-health-performance-during-jmeter-load-test

Getting this error on PerfMon, can someone help please. How shall I fix it ?

This is the image of the server agent

I'm running the test on localhost server, not sure ow to resolve this ERROR: java.io.IOException: Agent is unreachable via TCP

I recently run my gatling simulation scenario using maven following this tutorial,
It runs okay week ago, until recently I try to re run the scenario again then I got error
[main][ERROR][Gatling.scala:83] i.g.a.Gatling$ - Run crashed java.util.NoSuchElementException: null.

I run the scenatio with this command
mvn gatling:test -Dgatling.simulationClass=myscenario

I thought this caused by some corrupt repository? Because I see it points to gatling dependency.
I tried to reinstall the dependency with:

• mvn dependency:purge-local-repository - doesn't solve the issue
• mvn clean install -U - doesn't solve the issue
• rm -rf ~/.m2/repository - doesn't solve the issue

Here are the logs:

I have been through a lot of posts and solutions on excluding requests from certain domains from being recorded in my jmeter corelation recorder, but I still see those domains getting recorded in my script.

I tried entering this in Exclude urls: ^((?|mozilla>).)*$ to exclude mozilla and google.

but this does not seem to work at all, just like its pointed out here : Jmeter URL patterns to exclude under workbench - not excluding patterns that are giving there.

Also this link suggest similar solution :https://guide.blazemeter.com/hc/en-us/articles/206732519-Excluding-Domains-from-the-Load-Test

I want to exclude: mozilla.com , firefox.com and google.apis

Can someone please help ?
