node-red-configurable-ping

A Node-RED node which takes input and pings a remote server.

This is a modification of the node-red-configurable-ping node. The update is that the payload is now a boolean so that is easier to use with dashboard nodes.

Install

Run the following command in the root directory of your Node-RED install

npm install node-red-configurable-ping

Usage

• Pings a machine and returns the trip time in ms. Ping time is returned in msg.time. Returns boolean false if no response received within 5 seconds, or if the host is unresolveable.
• A boolean will be retured in msg.payload.
• Will perform ping on any input.
• You may override the host set in the configuration by passing in a value in msg.host.
• For legacy reasons, the node will output the host as msg.topic (the original node-red-node-ping does it this way).
• Any incomming data will be passed on to the output.
  • Incoming msg.payload data will be outputted as msg._payload (as the new msg.payload will contain the result of the ping).
  • Incoming msg.topic data will be outputted as msg._topic (as the new msg.topic will contain the the host).

Changes over node-red-contrib-advanced-ping

Ability to set ping options (timeout and number of requests). The defaults are:

• 5 seconds timeout
• 1 ping request
