Graylog - Strange characters in message

Hello, I’m seeing strange characters in the message field. I tried to change the input type but they are all coming out the same.

Any suggestions on how to fix this or where to look.


What type of client is
What’s the (syslog) configuration of that client?
What’s the configuration of the Syslog input in Graylog? is a Meraki Firewall. We are getting the same results from our Cisco ASA firewall too. Here is the info

We tried all 3 of these inputs and they all have the same results.


Here is the client side

Port 2055/udp is usually used for NetFlow, which is a binary protocol.

You cannot use a Raw/Plaintext or Syslog (which is also basically plaintext) input for that.
