The TICK stack is a collection of associated technologies that consists of Telegraf, InfluxDB, Chronograf and Kapacitor. They combine to deliver a platform for storing, capturing, monitoring and visualizing data that is in time series.

The TICK stack consists of the following technologies:

- #Telegraf – collection of tie sequential data from a range of sources including IoT devices.
- #InfluxDB – high performance and efficient database store for handling high volumes of time-series data.
- #Chronograf – real-time visualization of InfluxDB data.
- #Kapacitor – monitoring and alerting based on views of InfluxDB data and anomalies contained within those views.

Note: These components do not have to be used altogether. Also they can be replaced with other preferred tools (e.g. Grafana instead of Chronograf) or not used at all (e.g. Kapacitor).

## Telegraf

### Installation

Install the telegrafAUR or the telegraf-binAUR package.

### Configuration

Main configuration file is stored at `/etc/telegraf/telegraf.conf`. For available plugins, configuration and customization, see upstream documentation.

Also start and enable `telegraf.service`.

## InfluxDB

### Installation

Install the influxdb package.

### Configuration

For configuration, see upstream documentation.

Also start and enable `influxdb.service`.

### Upgrading from 1.8.x

InfluxDB 2.0.4 was released on 2021-02-25, and requires a manual upgrade step.

Note: The following appears to work, but was written by someone with little familiarity with InfluxDB. See FS#68763.

    # systemctl stop influxdb.service
    # influxd --bolt-path /var/lib/private/influxdb.v2/influxd.bolt --engine-path /var/lib/private/influxdb.v2/engine --v2-config-path /etc/influxdb/config.toml upgrade
    # mv /var/lib/private/influxdb /var/lib/private/influxdb.v1-backup
    # mv /var/lib/private/influxdb.v2 /var/lib/private/influxdb
    # mv /etc/influxdb/influxdb.conf /etc/influxdb/influxdb.conf.v1-backup
    # chown -R influxdb.influxdb /var/lib/private/influxdb
    # systemctl start influxdb.service

Edit `/etc/influxdb/config.toml` and remove `bolt-path` and `engine-path` lines (these are set correctly by the systemd unit).

## Chronograf

### Installation

Install the chronografAUR or the chronograf-binAUR package.

### Configuration

Main configuration file is stored at `/etc/chronograf/chronograf.conf`. For configuration, see upstream documentation.

Also start and enable `chronograf.service`.

## Kapacitor

### Installation

Install the kapacitorAUR or the kapacitor-binAUR package.

### Configuration

Main configuration file is stored at `/etc/kapacitor/kapacitor.conf`. For configuration, see upstream documentation. Many examples can also be found in official github repository.

Also start and enable `kapacitor.service`.
