Monitoring FTP Services

Oct 20, 2015

To monitor FTP services, the NetScaler appliance opens two connections to the FTP server. It first connects to the control port, which is used to transfer commands between a client and an FTP server. After it receives the expected response, it connects to the data port, which is used to transfer files between a client and an FTP server. Only when the FTP server responds as expected on both connections is it marked UP.

Note: Monitor probes originate from the NetScaler IP (NSIP) address.

The NetScaler appliance has two built-in monitors for FTP services: the FTP monitor and the FTP-EXTENDED monitor. The FTP monitor checks basic functionality; the FTP-EXTENDED monitor also verifies that the FTP server is able to transmit a file correctly.
