Hey #sysadmin hivemind, say you need to keep contents of a directory synced from a master to a ~dozen Linux servers. Not a lot of data, say around 10GiB. Most of it won't change often, some of it will change a couple of times per hour. Connectivity between the nodes is somewhat slow. You want metrics on what is the status of the synced directory and it's contents, preferably in a Prometheus-compatible format. Bash scripts and rsync would work but… surely there's something already out there?
