Ping and port monitors
Check that a server answers and that a service port accepts connections.
A ping monitor sends a ping to a host name or an IP address and counts it as up when the host answers. You can choose how many packets to send.
A port monitor opens a TCP connection to a host and port, for example a database on 5432 or a mail server on 587, and counts it as up when the connection is accepted. Enter the host and the port.
If your server sits behind a firewall, see Allow our checks through your firewall.
