UTC nanoseconds, and just started in this big circle, writing data can be successful but cannot be queried because of the wrong time. Java does not have a direct UTC nanosecond method, only System.currenttimemillis () gets the millisecond method. In fact, according to the millisecond and nanosecond conversion units, directly in the System.currenttimemillis () plus six 0 can be. Given the fact that there will be concurrent writes, the same data may be written within a millisecond, and the 6-bit

1: IntroductionInfluxDB 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.1, it has three major 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 data2. FeaturesSchemaless (unst

Getting Started with InfluxdbStep 3 After you start Influxdb, Influxdb launches an internal HTTP Server administration tool that allows users to manipulate

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
