/**
|
|
* Shows how to write data to InfluxDB via UDP
|
|
*
|
|
* UDP Writer Requirements:
|
|
* 1. Installed ext-sockets
|
|
* 2. Since Influxdb 2.0+ does not support UDP protocol natively you need to install and configure
|
|
* Telegraf plugin: https://docs.influxdata.com/telegraf/v1.16/plugins/#socket_listener
|
|
* 3. Extra config option passed to client: udpPort. Optionally you can specify udpHost,
|
|
* otherwise udpHost will parse from url option
|
|
* 4. Extra config option passed to client: ipVersion. Optionally you can specify the ip version,
|
|
* defaults to IPv4
