Check that the host you want to monitor is a supported host type.
DBmarlin supports monitoring of Linux hosts remotely via
ssh. This is typically over TCP port 22 to the
sshd daemon on the target server which needs to be open to allow DBmarlin to connect to it.
You will need either a private key file (PEM formatted) or a username and password to make the connection.
Adding the Host Target
This is done through the User Interface using the Add Host screen
ping hostnamefrom the DBMarlin server to the target host's IP address or name that you are using to see whether the name is resolvable and reachable.
telnet hostname 22to see whether the ssh port is open and you can establish a connection. If not there could be a firewall blocking.
ssh user@hostnameto see if you can establish an ssh connection to the target using a password.
ssh -i mykeyfile.pem user@hostnameto see if you can establish an ssh connection to the target using a private key file.
