Monitor System Metrics with the TICK Stack on CentOS 7

This article will guide you on how the TICK stack can be a powerful tool for storing, analyzing, and visualizing time series data. To monitor InfluxDB _internal metrics in a production #cluster, use Telegraf and the influxdb input plugin to capture these metrics from the InfluxDB /debug/vars endpoint and store them in an external InfluxDB monitoring instance.

More about Kapacitor:

#Kapacitor is a native data processing engine for #InfluxDB 1. x and is an integrated component in the InfluxDB 2.0 platform. 

Kapacitor can process both stream and batch data from InfluxDB, acting on this data in real-time via its programming language TICKscript.

A retention policy (RP) is the part of InfluxDB data structure that describes for how long InfluxDB keeps data. 

InfluxDB compares your local server's timestamp to the timestamps on your data and deletes data that are older than the RP's DURATION . 

A single database can have several RPs and RPs are unique per database.

Install InfluxDB on CentOS 7

This article will guide you on steps to Install #InfluxDB on #CentOS 7. You can Turn any InfluxData #instance into a production-ready cluster that can run anywhere. Easily create and share a comprehensive monitoring solution.

InfluxDB is similar to a #SQL #database, but different in many ways. Relational databases can handle time series data, but are not optimized for common time series workloads. InfluxDB is designed to #store large volumes of time series data and quickly perform real-time analysis on that data.

The local InfluxDB configuration file is located here: Linux: /etc/influxdb/influxdb. conf. macOS: /usr/local/etc/influxdb.

To Install InfluxDB:

Option 1 : Download the InfluxDB archive via the browser.

Option 2 : Adding the #repositories to your package manager.
