The TICK stack is a collection of products from the developers of the time-series database InfluxDB. It is made up of the following((https://www.digitalocean.com/community/tutorials/how-to-monitor-system-metrics-with-the-tick-stack-on-ubuntu-16-04))

components:

    * **Telegraf** collects time-series data from a variety of sources.
    * **InfluxDB** stores time-series data.
    * **Chronograf** visualizes and graphs the time-series data.
    * **Kapacitor** provides alerting and detects anomalies in time-series data.

You can use each of these components separately, but if you use them together, you'll have a scalable, integrated open-source system for processing time-series data.

In this tutorial you'll set up and use this platform as an open-source monitoring system. You'll generate a bit of CPU usage and receive an email alert when the usage gets too high.
