I just installed monit and checked the web interface. Unfortunately proftpd is marked as not running although it's running. I think it's because I'm running proftpd with S/FTP not FTP. Is it possible to run monit with S/FTP?
##CHECK ProFTPD
check process proftpd with pidfile /var/run/proftpd.pid
start program = "/etc/init.d/proftpd start"
stop program = "/etc/init.d/proftpd stop"
if failed port 21 protocol sftp then restart
if 5 restarts within 5 cycles then timeout
