I keep most of experimental data in a home-made databases, https://github.com/slazav/graphene/. Each database record contains a timestamp and multiple numerical values or text.
Data are collected to databases located on experimental computer and then syncronized with slazav.xyz server (usually with a 5-minute period).
Grafana web-interface is available on port 3000, http://slazav.xyz:3000. Example, Fridge2 temperature measurements during January 2020: http://slazav.xyz:3000/d/FE8XCICWk/f2?orgId=1&from=1577836800000&to=1580515199000.
Simple HTTP interface is available on different ports, depending on the cryostat. For example, ICTA (inner cell thermometer) database, January 2020, with 2-hour distance between points: http://slazav.xyz:8091/get_range?name=icta&t1=1577836800&t2=1580515200&dt=7200.
SSH read/write interface is also available.
Scripts for parsing Bluefors, Magnicon, Criomech, etc. logfiles and transferring data to databases are located in https://github.com/slazav/tcl-bf2gr/.
