Secure monitoring of servers by using SFTP

Last published : Sep 22, 2026
A user script ‘nssftp.pl’ is added to support SSH File Transfer Protocol (SFTP) monitoring. It is available in the current list of in-built NetScaler user monitors and is located in the /netscaler/monitors directory. The SFTP monitor uses the specified user name and password to check if the file is present on the server.
