We're working hard to prepare the cluster so we can have a nice calm holiday.
One of our monitoring tools shows flashing green lights if all is going well and red lights if a node is in trouble. We just had a wave of machines turn red! As the monitoring tool flashed green and red we couldn't help but notice it looked a bit like a Christmas tree!!
I thought I'd been a good boy this year, "Santa can I have a calm cluster for Christmas please?" ;-)
