If I were you, I would try:
- Change bind_address to
0.0.0.0in Input. - Try to lower number of
number_worker_threads: to 2 - After each change, try to start Input with
Start inputbutton and check log. - Check if the port 1514 isn’t used by another process:
ss -ulpn | grep 1514 - Check if you have
selinuxactivated, if yes change topermissiveordisabled. - If won’t help, try to create new Input with default parameter, change only non-used port to >1024 (other than 1514)
- If cisco can change syslog port to other than 514, change it directly to graylog input port, so don’t iptables to redirect
