InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
You'll want to download the plist file from here, and then follow the instructions on it. Once you do that, it should run continually in the background (though you won't be able to configure its settings from the app; you'll need to pass them all in as command line parameters).
Since version 0.7.0, I have also released SMCurser, a terminal-based client (a rewrite of my previous smserverreceiver, now in _Rust__) that has support for all the core features of the web interface, including sending attachments, typing indicators, and much more.
