POC Node.js Machines Ping Dashboard

A simple way to visualize the Node.js Machines inventory and perform a cyclical ping to collect network metrics with a full dockerize environment and a fancy dashboard.

Requirements

• Docker and Docker-compose
• Node.js

Features

• Download and digest the last inventory available in nodejs/build repository
• Simple NPM commands to manage the docker-compose infra
• Fancy dashboard
• Metrics are generated with Telegraf
• Metrics are stored in Influxdb
• Filter out non public Ips from the Node.js inventory

Preview

Setup

1. Get the last inventory version by running npm run start. This will generate the file ./telegraf.conf with all the IPs and domains.
2. Start the Docker infra by running npm run infra:start. This can take some minutes depending on your network
3. Go to http://localhost:3000/login
   • Login it with user admin and pass admin
4. Add new data source in http://localhost:3000/datasources/new as follows:
   • Select InfluxDb
   • HTTP url: http://influxdb:8086
   • InfluxDB Details Database: telegraf
   • InfluxDB Details User: root
   • Click in Save & Test
5. Import a fancy dashboard in http://localhost:3000/dashboard/import
   • Add id 2690 and press Load
   • (In the next page) Select InfluxDB and press Import

Stop

Just run npm run infra:stop

Refresh the hosts list

1. Stop the infra npm run infra:stop
2. Update the hosts lists npm run start
3. Start the infra npm run infra:start

Change Telegraf settings

Make any change in src/telegraf.conf and this file is extended with the hosts ips
