Note that you can gather and display logs with this same stack, Telegraf includes a plugin to consume syslog output: https://github.com/influxdata/telegraf/blob/release-1.14/plu... and then you can do something like this on Grafana: https://grafana.com/api/dashboards/12433/images/9004/image

The one thing I would add to this guide is enabling HTTPS for the whole stack, if you are transmitting over the public internet. Fortunately, it is quite straightforward (and free) with Let's Encrypt.
