Ping Host Operator

The Ping Host operator lets you evaluate access to a given host or IP Address. You can specify the number of requests to make to the remote host, and the timeout and TTL values. You can also specify the local IP address of the computer on which the operator is running. In this case, the operator uses the local network interface that is associated with the local IP address to initiate the ping operation.

The output variable: "isHostReachable" indicates whether the host is reachable.

If any of the ping requests indicates that the host is reachable, then "isHostReachable" is set to True.
If all ping requests indicate that the host is not reachable, then "isHostReachable" is set to False and the operator fails.

The Ping Host operator fails when an error occurs or when all ping requests to a host fail.

To ping the destination host, the Ping Operator uses ICMP echo requests if the privilege can be obtained, otherwise it attempts to establish a TCP connection on port 7 (Echo) of the destination host. Typically, port 7 is blocked and a TCP connection cannot be established.

On Windows, the Ping Operator may not use ICMP protocol (a java limitation), hence, run this operator on a *nix Agent or Orchestrator. Alternatively, you can use the Run Script operator to call the OS Ping command.

Firewalls and server configuration may block a ping request, resulting in an unreachable status.
