node-red-contrib-advanced-ping

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

This is a modification of the node-red-node-ping node. Difference is that this node will perform a ping when it recieves input where the node-red-node-ping node performs pings on a set interval. You may also programmatically pass ping settings to this node. For periodical checks, wire an inject node to this ping node.

Install

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

npm install node-red-contrib-advanced-ping

Usage

• Pings a machine and returns the trip time in ms. Ping time is returned in msg.payload. Returns boolean false if no response received within 5 seconds, or if the host is unresolveable.
• 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).

Todo

Ability to set ping options in node configuration/by incomming message. Right now, these settings are hardcoded

• Linux: -n -w 5 -c 1
• Windows: -n 1 -w 5000
• Mac: -n -t 5 -c 1
