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.
A potentially cheaper option: get yourself a small-to-mid-sized Android tablet or Chromebook (7-10" is the sweet spot for this for me, if that helps) and figure out a way to stand it up on your desk, and get an app called Matric on that and your PC. You can run it for free but features are very limited until and unless you spend the (I think) $15 to unlock the paid version. But you can download and install several button cards for various applications, from DCS and Star Citizen to OBS or Photoshop or whatever you want; it's basically a virtual, endlessly customizable button box.
