SFTP Monitoring

Can an SFTP port be monitored with the full handshake? Right now it looks like our F5 is just completing a port check (similar to a telnet to the port) that is causing an error within the SFTP server...

Hi,

 

 

If a TCP port check is causing an error, You could create a script which calls sftp on the BIG-IP to connect to the pool members and verify they answer correctly. Once you have a script which can run on the BIG-IP, you can reference that in an external monitor. You can check the Monitoring codeshare section for examples of external monitors.
