Morning, List.
I recently upgraded one of my large (1k osd) clusters from Jewel to Luminous. The upgrade went wonderfully smoothly, and I've now got 3 mgrs running as well.
One of the things I was most looking forward to getting my hands on was the "native" prometheus exportor. I enabled it as per the documentation, and scraped it:
time curl sct-r1-r1-head1:9283 | wc -l
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 18.5M 100 18.5M 0 0 424k 0 0:00:44 0:00:44 --:--:-- 297k
342772
real 0m44.715s
user 0m0.224s
sys 0m0.562s
That's ... a *lot* of metrics. Just wondering how large of clusters this has been tested with. It seems to me I'm going to need to turn off some metrics and/or break them into different types of requests to get decent scrape times and small enough scrapes that I can provision a prometheus server to actually be able to ingest it. Has anyone else with a large cluster looked at this yet?
FWIW, the dashboard plugin performs fairly admirably as long as I don't go to the OSDs page...
