I have not yet used etcd but I might in an upcoming project with the goal being to sync configuration for 50-100 servers. The thing is that I might need to perform some actions on each machine once some change is made. Does etcd support some kind of observability that I can hook into?

Please refer to this API: https://github.com/etcd-io/etcd/blob/76e769ce95ca0d4d0e3486712d96956260db04b8/clientv3/watch.go#L75
As an example, the command line tool etcdctl uses this API. Free feel to play with it so see if this is what you need.
