+/**
+ * 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
