Grafana is a data visualization and monitoring tool allowing you to show metrics stored for example in InfluxDB as charts. It gives you possibility to create dashboards to link charts or histograms into connected groups. Thanks to built-in InfluxDB support it automatically handles provided aggregation functions. Query editor supports also tag or field completion.
InfluxDB it is a database oriented on time series. It was designed to accept large number of queries and write requests. It is perfect for storing timestamped data – data we would like to query by timestamp rather than index. It supports SQL-like language to easily pull data off as well as JSON requests through HTTP API. Influx uses tags and fields - tags to easily index series of data (you can query by it after where clause) and fields for keeping values (select field_1, field_2 from … )

We live in the world where we are bombarded with huge amount of information, news and advertising. Computer network becomes the central place of business. For this reason databases become fatter and fatter.
