janvda/ping repository overview

⁠node-red-ping

github location: janvda/my-ping⁠

1. This flows measures every 5 sec the ping times of several hosts and shows it in the Node-RED UI dashboard (see screenshot dashboard⁠)
2. Moreover these ping times are also stored in an influx database (http://influxdb2.local⁠) which are visualized by the following 2 influx db dashboards:
   • ping
   • ping-dev
3. Logs internet disconnect/connect in the container log file.
4. every 6 hours does a speedtest to measure internet upload/download speed.

⁠Prerequisites

Requires an influx database which is specified by following environment variables (see .env file)

• INFLUXDB_URL=http://nuc2.lan:8087⁠
• INFLUXDB_TOKEN=m......n
• INFLUXDB_ORG=my-org

⁠Notes

1. macOS’s firewall can block the ICMP packets that ping uses, which will interfere with this test. Make sure you disable “Stealth Mode” in “System Preferences”->“Security & Privacy” -> “Firewall
2. Currently my macbook doesn't get the same IP address from DHCP - so you might need to manually update the flow for this.
