For users with 64-bit systems, it’s available as a Ubuntu/Debian package as well as packages for Redhat/CentOS, OS X, Standalone use and Docker.
Installation is easy. It’s a single file with no external dependencies. (as is Grafana)
e.g. the command sudo dpkg -i influxdb_0.13.0_amd64.deb
is all that’s needed to install the current (as of this writing) Debian version.
It’s easy to use. i.e. the write and query APIs are easy to understand.
The Query Language is similar to MySQL.
ARM as well as X64 processors are supported, which means it will run on a Raspberry Pi.
Performance on a Pi 2, while not blazing fast, is definitely not bad.
X86 CPU versions aren’t produced by the developer, and although influxdb is easy to compile from source code, that’s something most users are not going to want to deal with, so is likely to be a show-stopper for many.
FWIW, here’s an example of Influxdb and Grafana: tppg.mooo.com
It’s running on a Virtual Private Server, so performance is very good. I’ve run a copy of Influxdb/Grafana on an Intel Atom N270 based nettop with 1GB of RAM with good results.
