Bump. A reasonable query I think, because running with 512MB opens up a whole different universe of hosts for users with simple requirements.
My experience is with a default install of influxdb 1.1.1, grafana 4.0.2 and kapacitor 1.1.1. Points arrive via HTTP at about 2500/day. There's two databases with series cardinality of 21 and 1 (the latter is for grafana annotations), plus the _internal database with 188. Other than manual viewing of data with grafana, the only other non-default queries are made by a kapacitor script that processes the stream from one measurement and writes to another. I'm running with 512MB, and every week or so Influx quietly dies, with an OOM message left in syslog. Runs perfectly fine on restart, with about 150MB free (as reported by free -m). Given how outrageously far I am from sweating influxdb's capabilities (the hardware sizing guidelines start at series cardinality of 100,000), it seems there ought to be a configuration that will happily run on 512MB. Rolf, your results are impressive. Have you noticed much change over time?
