InfluxDB is an open source distributed timing, event, and metrics database.Written in the Go language without external dependencies. Its design goal is to achieve distributed and horizontal scaling expansion.It has three main features:1. Time series (timeseries): You can use time-related functions (such as Max, Min, sum, etc.)2. Metrics (Metric): You can calculate large amounts of data in real time3. Eevents (Event): It supports arbitrary event dataCh

INFLUXDB can process tens of thousands of data per second, saving all of this data in a large amount of storage space, and sometimes we may not need to store all of the historical data, so INFLUXDB introduced a data retention policy (Retention policies), Used to allow us to customize the data retention time.

configuration options, you can view the Cadvisor project documentation on GitHub.
InfluxDB: It is a distributed time series database. Cadvisor only displays real-time information, but does not store monitoring data. Therefore, we need to provide a time series database to store the monitoring information provided by the Cadvisor component in order to display timing data in addition to live information.

Build a modern monitoring system using Grafana, collectd, and InfluxDB
To create a beautiful real-time monitoring system like New Relic, we only need the three InfluxDB, collectd, and Grafana tools. The relationship between these three tools is as follows:
