We're a bit of a weird case in that we log data at 20Hz and 100Hz for prototypes, so we need custom queries and/or aggregation to reduce that down for display. We had a good chat with Inductive earlier this year, but even they said that might be a bit much for them. Other than that, though, Ignition is literally everything we want in a single product.

Telegraf can do this too, in a more limited capacity. It keeps an in-memory buffer of collected data points so if a write to an output fails it'll try again on the next interval without losing the data it has already collected.
