Have you deployed them? Tested they work?

[QuantumEnigmaa]

I'm currently doing it :)

It would be nice to add a document explaining where these dashboards come from, and what you had to do to fix them.
Like here: https://github.com/giantswarm/dashboards/tree/master/loki

[QuantumEnigmaa]

Some graph display interesting data but most of them will need to be adapted to our setup :

[QuentinBisson]

Would you think it makes sense that we add them one by one ? Because we probably don't need them all, yet and also because fixing and screenshottig will bé easier

[QuentinBisson]

Can you post a screenshot when it works?

[QuantumEnigmaa]

This is what the dashboard looks like currently (at least the most interesting parts) :

On the second screenshot, one can have an overview of the regular cycles where the ingester uploads its data to the object storage.

[QuentinBisson]

This is nice :)

Maybe we could reduce the interval between compactions :D

[QuentinBisson]

Do you want to add the others in this PR ? If not,can you list hte dashboards we want to add in the parent issue?

[QuantumEnigmaa]

Maybe we could reduce the interval between compactions :D

Yeah, but this is outside of the scope for this issue x)
But I agreee that if possible, it could be nice to reduce it to save on resources !

Do you want to add the others in this PR ? If not,can you list hte dashboards we want to add in the parent issue?

I will create other PRs for the other dashboards and I'll write those ones in the issue :)

[QuantumEnigmaa]

Sorry, late change in plans : I'm also adding the writes-resources dashboard in this PR as it's write related 🙇

[QuentinBisson]

Screenshot or it did not happen :)

[QuantumEnigmaa]

Apart from the disk storage graphs (which I'm currently working on), we have nice data :

[QuentinBisson]

Should we add the networ dashboard here as well?

[QuantumEnigmaa]

Woops my bad sorry
