File Transfer Protocol (FTP) is a standard network protocol used to copy a file from one host to another over a TCP/IP-based network, such as the Internet. |
FTP server monitor provides FTP server operability testing by checking server status and reading attributes of a remote file using FTP protocol.
Synchronization Details
FTP monitoring configuration settings are described in FTP Service Settings subsection.
The following operations are performed during synchronization:
| • | Connection to FTP server is established. |
| • | Authentication procedure is passed. |
| • | Server status information is obtained and saved in monitoring results. |
| • | File is located using path specified in parameters. |
| • | File timestamp (which is usually its last modification time) and size (in bytes) attributes are obtained. |
| • | Disconnection is performed. |
All these operations should be successfully finished to make the service Online. Server status and file information are stored as monitoring results.
If any of the operations fails the server is deemed Offline. Error encountered during synchronization is saved in the monitoring results.
|
Note that a path specified in service configuration should refer to a regular file (i.e. not point to a directory or include wildcard characters). If monitor is unable to find the file using specified path the FTP service is deemed Offline. |
