Aruba Central Webhook integration with Slack

README.md

Overview

Aruba Central is a cloud-based network management and monitoring solution for Aruba Instant Access Points, Switches, and SD-WAN gateways. It has lots of Alerts to notify IT managers network problems.
To receive these Alerts on Slack, you can use this Flow.

Usage

• Setup Aruba Central Webhook to Node-RED on public server. (I used AWS)
• Setup Slack to receive incoming Webhook.
• Setup Node-RED Flow as a relay server.

Traffic Flow

Aruba Central --> Node-RED@AWS --> Slack incoming Webhook

How to setup Aruba Central Alerts and Webhook.

General Alert Configuration

Take a look at the Aruba's document.
You can choose Email or Webhook to send each Alert.

Webhook

• Go to "Maintenance" > "API Gateway" > "Webhook", then create a new Webhook.
• Put Your Node-RED URL there. (eg. http://your_server_address:1880/webhook)

How to setup Slack incoming Webhook

Take a look at the Slack's document.
You only need a Webhook URL like "https://hooks.slack.com/services/T00000000/B00000000/XXXXXXXXXXXXXXXXXXXXXXXX"

How to setup Node-RED Flow.

• In "Set Values" function, set Slack's Webhook URL as msg.url.
• If you need to modify messages to Slack, change "Set Messages" function.
