Monitor Type: Basic Connectivity

Monitor TypePropertiesBasic connectivity

PING

Packet Size, bytes – specifies the number of data bytes to be sent. The default is 32, which means 40 ICMP data bytes when combined with the 8 bytes of ICMP header data

Reverse monitor (OK when no PING) – if set, the monitor is in the OK state when there is no answer from the host to the PING request. IF the host replies to the PING, the monitor is in the DOWN state.
TCP

Port (integer)

Reverse monitor (OK when TCP port is off) – if set, the monitor is in the OK state when the specified TCP port cannot be connected to. IF the connection attempt is successful, the monitor is in the DOWN state.
UDP

Port (integer)

Data in Hex to be sent to the server

Expect Echo Response – if TRUE, the monitor compares the server response with the data it sends; otherwise any response is acceptable.

Frequently Asked Questions

Check out our Knowledge Base where we answer questions regarding various topics.

When is a PING monitor useful?

Use a PING monitor to check basic ICMP reachability. You can set the packet size and optionally reverse the result so the monitor is OK only when there is no PING reply.

What does a TCP monitor check?

A TCP monitor checks whether a specific TCP port can be connected to. With reverse monitoring enabled, the monitor is OK when the port is unavailable and Down when the connection succeeds.

How does the UDP echo response option work?

When Expect Echo Response is enabled, the monitor compares the server response with the hex data it sent. When it is disabled, any response from the UDP service is treated as acceptable.
