I'm running some servers with a docker container.
Recently I've seen that disk space on my root disk (inside docker) is getting low. That disk is "mapped" as /mnt/stateful_partition in the physical machine.
I've searched for big files in the physical disk and I've found one that puzzles me:
/mnt/stateful_partition/var/lib/metrics/uma-events
That file keeps growing evey day (roughly 5 MB a day) and it's eating up all my disk space.
One of my server was created back in october 2019. Now that file (uma-events) is 3.558.914.410 bytes and is written in a partition that is roughly 7 GB... and I've only 800 MB left. At 5 MB/day it's gonna be full in about 5 month... :-|
The file contains something like this:

What is it uma-events? Is there a way of enabling an automatic rolling or something? Can I switch it off?
