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 data Retention Policies and influxdbretention InfluxDB can process thousands of data records per second. To save all the data, it will occupy a lot of storage space. Sometimes we may not need to store all the historical data. Therefore, influxDB introduces a Retention policy to allow us to customize the Retention time of data. For more details about

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.

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: Collect data-> store data (InfluxDB)-> display data (Grafana ). Inf
