Increase retention time of graphite stats for CI

Description

My current need is for gate-and-submit. The data doesn't exist pre-6 months ago:
https://grafana.wikimedia.org/d/000000108/releng-kpis?orgId=1&from=now-6M&to=now&fullscreen&panelId=18

This is preventing me from reporting on our work effectively.

greg created this task.

In other panels I see data going back to Aug 2017 for core's gate-and-submit, e.g. https://grafana.wikimedia.org/d/000000108/releng-kpis?orgId=1&from=1496046004105&to=1579080951474&fullscreen&edit&panelId=2 maybe it has to do with the panel's query ?

thcipriani subscribed.

tentatively assigning to greg to see if he can figure out what's going wrong with that panel. Reassign as needed :)

My guess is that it has to do with me trying to get ALL metrics vs just mw/core:

(Yes, they're "disabled" aka not shown, but they're referenced later down when doing the std deviation etc)

So, there's probably some metric that only goes back to ~6 months and that's limiting the overall summary.... hmmmm.

I want all metrics, but I want it to go back as far as it can.

@fgiunchedi do you know of any options of doing that?

No idea @greg right off the bat, although I see the panel Gate and Submit "Resident Time" on top left is working as expected so I take it is possible in some fashion

greg lowered the priority of this task from High to Medium.

So yeah, my previous comment is right and I'll just need to fiddle with metrics to get them to give me what I want when I hit this issue.
