We've mounted a graylog2 dedicated server (with a rails unicorn, mongodb and eleasticsearch) on a virtual machine with 2gigs of ram a couple days ago.
RAM Consumption just keeps climbing, I am getting high consumption alert quite frequently.
I'm trying to evaluate how much RAM I'll need to centralize all syslogs and rails logs for 25+ servers, any one has experience about this ?
Alternatively, does anyone have a way to keep graylog2 and his dependent applications (unicorn, mongodb, eleasticsearch) under 2gigs of RAM ?
EDIT 2013-02-20: It turns out, RAM is not really the problem after a little boost to 2.25 GB. The Problem is now the CPU load, we've got graylog-server consuming almost 100% of all 8 cpu cores.
