Install Kapacitor
前言
InfluxDB 是一款高性能的时序数据库，见长于标量的时序存储
类似于 Elasticsearch 的 ELK 技术栈，InfluxDB 也有一套 TICK 技术栈
其中 Kapacitor 是一个实时的流处理引擎，可以对流数据或批量数据进行计算和处理
Kapacitor is a native data processing engine in the TICK Stack. It can process both stream and batch data from InfluxDB. It lets you plug in your own custom logic or user-defined functions to process alerts with dynamic thresholds, match metrics for patterns, compute statistical anomalies, and perform specific actions based on these alerts like dynamic load rebalancing
这里分享一下 Kapacitor 的安装方法
Tip: 当前的版本为 kapacitor-1.4.0

[root@much ~]#依赖
在 TICK 技术栈中，Kapacitor 和其它组件的关系如下
tick
InfluxDB 和 Chronograf 还有 Telegraf 的版本要求
- InfluxDB - While Kapacitor does not require InfluxDB, it is the easiest integration to setup and so it will be used in this guide. InfluxDB >= 1.3.x will be needed.
- Telegraf - Telegraf >= 1.4.x will be required.
- Kapacitor - The latest Kapacitor binary and installation packages can be found at the downloads page.
- Terminal - The Kapacitor client application works using the CLI and so a basic terminal will be needed to issue commands.
