Netdata: How to increase historical data storage to at least a few hours?

[COLABORATI]

Maybe something is wrong with my version of net-data, but I can not see any historical data, not even for the last 24 hours - reading your wiki that seems to be a feature? - however, I do not understand how you would not have the idea to at least implement a small scale historical puffer for at least 24 hours - that would help a lot in many situations - I do not know anybody staring at live views of sensor data whole day, that concept makes absolutely no sense at all. Of course you want to have at least a small historical view.

So hopefully I have overlooked some config value - how would I configure net-data to have at least 24 hours of data available for review? Thanks!

It's configured via the history key in the [global] section of the configuration file. The value is specified in seconds, so for 24 hours you need history = 86400. Note that this will increase memory usage significantly.
