Monitor SFTP site connection

Has someone already created a data source that checks a SFTP connection to a specific site? I saw there was one created a few years ago but the link is dead.

In that case, you could take out the two code blocks that start with:

// Print the contents of the file with the given file name

// List the contents of the default directory

Thanks I will take a look at this. All I need it to do for now is make sure an account can be authenticated.

Chat-GPT prompt FYI:

Write a Groovy script to connect to a given SFTP server, log in using a given user name and password, list the contents of the default directory, and print the contents of a file with a given file name. If the file with the given file name is not present, print a message indicating that.

Chat-GPT to the rescue:

@Grab('com.jcraft:jsch:0.1.55')<br/>import com.jcraft.jsch.*<br/><br/>// Set the SFTP server connection details<br/>def host = "example.com"<br/>def port = 22<br/>def username = "username"<br/>def password = "password"<br/><br/>// Set the file name to be read<br/>def fileName = "example.txt"<br/><br/>// Create a JSch session<br/>JSch jsch = new JSch()<br/>Session session = jsch.getSession(username, host, port)<br/>session.setPassword(password)<br/>session.setConfig("StrictHostKeyChecking", "no")<br/>session.connect()<br/><br/>// Create an SFTP channel and connect it to the session<br/>ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp")<br/>sftpChannel.connect()<br/><br/>// List the contents of the default directory<br/>def files = sftpChannel.ls(".")<br/>println("Files in default directory:")<br/>files.each { file -><br/>    println(file.filename)<br/>}<br/><br/>// Print the contents of the file with the given file name<br/>try {<br/>    InputStream inputStream = sftpChannel.get(fileName)<br/>    println("Contents of file $fileName:")<br/>    println(inputStream.text)<br/>} catch (SftpException e) {<br/>    println("File $fileName not found")<br/>}<br/><br/>// Disconnect the SFTP channel and session<br/>sftpChannel.disconnect()<br/>session.disconnect()<br/>

Although, you don’t need to Grab on the first line because jsch is already installed on the collector. This is eerily close to the example in monitoring-recipes. Hopefully between the two, creating a new scripted datasource won’t be out of reach. Let me know how it goes.

Do you just want to know that the port is open and accepting connections on a TCP level? Or do you want to do more (authenticate, look for a file, check a file size/contents)?
