@bithead/node-red-ays-agent 1.1.3

Send sample values from HW/SW agents to the At Your Service Agent Service.

npm install @bithead/node-red-ays-agent

Node-RED ays-agent

This provides an interface to the At Your Service agent from within Node-RED. This is accomplished by adding an ays-agent subflow and adding two global environment variables.

Installation

Please note: The agent has only been tested on Node-RED v3.1.6.

Install the Subflow

There are two ways to install the ays-agent subflow.

1. Node-RED

• Open Node-RED
• Top right menu button > Settings > Palette > (tab) Install
• Search for the bithead/node-red-ays-agent module
• Install

2. NPM

• Open a terminal
• Change directory to the Node-RED config directory (e.g. cd ~/.node-red)
• Install module using NPM npm install @bithead/node-red-ays-agent

Usage

Drag the ays-agent node into your flow. It should be located in the network category.

Connect any of your HW/SW systems to the ays-agent input. The input must be a numeric value.

Parameters:

• Config global configuration that can be used by an ays-agent node instance
  • Server the location to the AYS Agent Service endpoint
  • Org Secret the respective secret for the organization node sending samples to
  • Parent (optional) the path to the parent node. Set this value if you intend to use the same parent for all agents.
• Parent Node the path to the parent node. Your child lives under this node. Leave this empty to use the Config.Parent Node value. Otherwise, it will override the value.
• Child Node The name of the child node. Please use the character range [a-z0-9], or the hyphen (-) character, where the first character in the name is a letter. e.g. my-node-01
• Monitor Name (optional) The name of the monitor. If none is provided, node-red is used.
• Threshold (optional) Trigger a threshold if a value falls outside of specified range. Refer to the ays-agent API docs for a list of supported threshold formats.
• Heartbeat (optional) The default is set for 5 minutes. If you don't want to monitor the node, set the heartbeat value to 0.
• Template (optional) Adopt a template located at the specified node path.

Debugging

The ays-agent subflow emits node.errors messages (which can be seen in the Debug panel) and provides node status messages hints that display under the ays-agent subflow instance. If an node status is displayed, please open the Debug menu for more information.

The most common problems are:

• A required parameter is not provided
• Connection to the AYS server failed
