InfluxDB is a time series database built from the ground up to handle high write and query loads. It is the second piece of the TICK stack. InfluxDB is meant to be used as a backing store for any use case involving large amounts of timestamped data, including DevOps monitoring, application metrics, IoT sensor data, and real-time analytics.
All configuration is done in
/etc/influxdb/influxdb.conf. By default, it listens at https://localhost:8086 for data.
The configuration is well documented, but you can also have a look at their Documentation
The InfluxDB can be used as part of the TICK stack. In this setup, data is written into the database using Telegraf. Kapacitor and Chronograf then use the database to send alerts and display data respectively.
