How to collect metrics from node.js applications in PM2 with exporting to Prometheus
This approach will work as long as you don’t need to run multiple instances of the application in cluster mode. For collecting metrics in cluster mode, prom-client provides a good example with metric aggregation. But what if you’re running the application through the process manager PM2, where you don’t have access to the running cluster?

Trying to Monitor and Alert on Process Downtime for Azure Linux VMs
You would need to build a custom endpoint if it's a custom application that Prometheus can scrape but there are many libraries for that like prom-client for NodeJS or prometheus-net for C#. The list of client libraries can be found here.

Monitoring consumer lag in Azure Event Hub
Consumer lag will quickly show any functional or technical issue with your event stream. By using the code examples from this blogpost, you can avoid having to dive into the SDKs yourself. Of course, you can adopt the metric collection to send the metric to the logs or to another metrics system like prometheus, datadog, or open telemetry.

Set Up Tracing for a Node.js Application on AppSignal
One of the easiest ways to send lots of fabricated requests at the same time is to use the Vegeta load testing tool. Being a load testing tool, it can send lots of requests consistently, every second, to the given target URL. You can read more about Vegeta on GitHub. The binary can be downloaded and used without installation.

What tools you use for http load testing?
Good morning what tool do you use to test your infra in terms of http load ? A tool that works, I tested : - https://github.com/tsenart/vegeta but it returns 0 errors or a http_net error from Golang - LOIC (Low Orbit Ion Canon) https://github.com/NewEraCracker/LOIC but the requests do not appear in my nginx logs and I feel no slowdown - Apache Jmeter https://jmeter.apache.org/ but I can't drop my infra and I have Java socket closed errors - K6 https://k6.io/ but I can't bring down my infra with - wrk https://github.com/wg/wrk no matter what parameter I put it doesn't make enough requests per second, I put the same parameters as on a tutorial and I don't get the same result...

How to Deploy and Scale Strapi on a Kubernetes Cluster 2/2
But for the purposes of this article, given that we want to show the process, we will run everything on the same computer. We will use the tool vegeta, and if you want to read more about it, you can read this article. Our Strapi project is based on the Getting started guide, therefore we have restaurants and categories, so we will use these endpoints.
