A host that I monitor is not reachable via ping (ICMP), how can I use a host check on a different protocol, such as a TCP port?
To change the host check command to verify that the host is up, do the following:
- Navigate to the configuration page of the host
- Click "Advanced"
- Find the configuration option "check_command"
- Change to one of the predefined commands "check-host-alive-*"
You can also create your own port check using the plugin "check_tcp" or any other plugin of your choosing. More information on check commands can be found in the documentation in the chapter Commands
