appmetrics | Node Application Metrics | Performance Testing library

I have an electron app with multiple browserWindows.
For my own help, I spawn them with additional arguments (for example: '--renderer-mode="second-window"').

Now I want to collect Metric Data of my current electron processes.
I already have a IPC interface in my main process I call from one of my renderer.

First off a little new to using helm...

So I'm struggling to get the helm deployment of this: https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack

To work the way I would like in my kubernetes cluster. I like what it has done so far but how can I make it scrape a custom endpoint? I have seen this: https://github.com/prometheus-community/helm-charts/tree/main/charts/prometheus

Under the section titled: "Scraping Pod Metrics via Annotations". I have added the following annotations to the pod deployment (and then the node port service) in kubernetes:

I am using the logging extension framework in an asp.net core function app. I have following code:

I the Node.js package apiconnect will not install on my new MacBook Pro. The Node.js version is v10.22.1, NPM version 6.14.6, Python 3.8.3

I ran the following command:

I'm working on another machine today. I've pulled my code from GIT and can see the project source files. But when running npm start I get the following error:

I have a Spring Boot app using OpenTracing and I would like to push its data to Prometheus, so I can query all metrics via Grafana (like in this tutorial https://www.hawkular.org/blog/2017/06/26/opentracing-appmetrics.html).

The problem is, I haven't found any consistent solution to do this, all the examples that I have found so far are outdated, deprecated or lacks documentation.

Ideally, I am looking for some solution which returns an instance of io.opentracing.Tracer, similar to what Jaeger does:

I am new to Grafana. I have a dashboards like below and I want to add one more list call appmetrics under the kafka metrics. I do not know how to add it. Thank you for the help.

Summary

I'm trying to figure out how to properly use the OR | operator in a Prometheus query because my imported Grafana dashboard is not working.

Long version

I'm trying to debug a Grafana dashboard based on some data scraped from my Kubernetes pods running AppMetrics/Prometheus; the dashboard is here. Basically what happens is that when the value "All" for the server is selected on the Grafana dashboard (server is an individual pod in this case), no data appears. However, when I select an individual pod, then data does appear.

Here's an example of the same metric scraped from the two pods:

I have several methods in my class, each taking in different parameters and returning different parameters. For each of those methods, I want to wrap them in a common piece of code that would do some time logging. For example., when the method starts, it logs the start time and when it ends, it logs the end time and so on.

I have this method implemented:
