I've been using InfluxDB for ~3 years now for storing metrics (almost exclusively via Telegraf, a few custom ones), and it has been great! It replaced a collectd setup and dramatically decreased load across my fleet.

When I first started using it, it was pretty early and had some issues. In fact, I nearly trashed it. I also didn't like the pull vs. push model from Prometheus. They ended up resolving the InfluxDB issues I was having right as I was about to give up on it, and it's been solid since. I use it with Grafana to generate graphs of system use. I set it up before TICK was a thing.

Push gateway?

I'd recommend giving a try to VictoriaMetrics. It requires less hardware resources - RAM, CPU, disk - comparing to InfluxDB [1] and it supports PromQL - much nicer query language for typical time series queries comparing to InfluxQL or Flux [2]. It may be used as a drop-in replacement instead of InfluxDB on the ingestion path [3].
