Use a file watcher to detect changes on a remote Linux server

I have a requirement of detecting addition of new files into a folder on a remote Linux server that follows SFTP for its connection.

Right now I am trying to detect the changes from local(windows OS ) by using Java nio Watch service, but it seems it can work for local file changes or shared drive file changes.

I can't post my code due to some genuine reason, but I have used jsch to connect to SFTP server and Java nio Watch service to detect the file changes.

I will be deploying the java springboot app on openshift as a docker container(can jsch and watcher service be used for linux based containers to detect file changes on remote linux SFTP server?).

I went through Google and got few answers but I am confused a bit.

Want to know a better approach to detect the file changes on remote SFTP based Linux server.

Much thanks for the help!!

Checkout the rdp4j library :https://github.com/drapostolos/rdp4j/wiki/User-Guide

As you are using jsch, another (somewhat hacky) option is to simply run a Linux command on the remote server and grab the list of files modified between X and X+n timestamps. You can specify precise timestamps programatically and run it on a schedule (all file "pollers" are basically scheduled jobs that keep checking super frequently)

find /tmp -type f -newermt "2020-08-12 15:01:00" ! -newermt "2020-08-12 15:02:00"

The find command's "newermt" option lets you specify precise timestamp ranges, and you can avoid the guess work that comes with -mmin or -mtime option.
