Official grafana dashboard issues

[budras-nexus]

Brief summary

Hello everyone,

using the official grafana dashboard I experienced some issues in the data aggregation:

k6 version

1.0.0

OS

ubuntu

Docker version and image (if applicable)

No response

Steps to reproduce the problem

1. Start a parallel run with reporting to prometheus
2. Evaluate the data using the grafana dashboard https://grafana.com/grafana/dashboards/19665-k6-prometheus/

Expected behaviour

Requests number to make sense, add up to the numbers reported on the console

Actual behaviour

Strange behavior, more requests failed than actually sent.

I had some issues with parallelism before too and the team said parallelism wasn't supported atm. grafana/xk6-output-prometheus-remote#174

I ended up no going down the rabbit hole but I guess it might be a bit tricky to get all data to align properly.

Yeah looks like a duplicate. However, I think this is/can be a really bad surprise and should be prominently added to the dashboard description if not fixed.

Hi @budras-nexus,

I'd be happy to help you, and to try to fully understand if this is something we should really fix, or whether it's something that goes beyond the scope of this dashboard, shared for inspirational purposes rather than as a battle-tested production-ready one.

But for that, could you please provide more detailed instructions of how to reproduce this issue? Ideally, I'd like to see a minimal script that reproduces the issue, how did you run k6 (command), and how many times, and later what's the query that's showing confusing value (like, what metric? are you filter by any specific tag?, etc).

Once I can manage to reproduce the issue, I'll be able to determine what's the best way to proceed.

Thanks!
