InfluxDB is the highest-ranked time-series DB on the market, and it offers a good set of tools to work with and visualize your data. For this to work, you need to be aware of two things: retention policy and continuous query. The solution is perfect for a simple case without tags in aggregated data. Using it with tags-heavy data would result in several entries with one timestamp that would overwrite over each other, causing each time period to have only one entry.
