The open source TICK Stack, which includes InfluxDB, is a high performance platform to collect, store, visualize and act on time-series data for DevOps metrics, IoT telemetry, and real-time analytics. The four TICK Stack components: Telegraf for collecting data, InfluxDB for storage, Chronograf for graphs, and Kapacitor for alerts; contain everything needed to make beautiful dashboards, observe Kubernetes clusters, store syslog messages, and even monitor your smart home. Get started in 60 seconds with the InfluxDB TICK Stack 1-Click App.

The open source TICK stack, which includes InfluxDB, is a high performance platform to collect, store, visualize and act on time-series data for DevOps metrics, IoT telemetry, and real-time analytics.

The four TICK stack components include:

• Telegraf, for collecting data
• InfluxDB, for storing time series data
• Chronograf, for graphs and dashboards
• Kapacitor for alerting on changes

DigitalOcean's InfluxDB (TICK stack) One-Click application by InfluxData includes all you need to quickly make beautiful dashboards, observe Kubernetes clusters, store syslog messages, and even monitor your smart home.

Components

Component	Version
Linux	Ubuntu 18.04.1
Telegraf	1.9.4
InfluxDB	1.7.2
Chronograf	1.7.7
Kapacitor	1.5.2

In addition to the package installation, the One-Click also:

• Enables the UFW firewall to allow only SSH (port 22, rate limited), HTTP (port 80), and HTTP (port 8086) access.
• InfluxDB is running on port 8086.
• Chronograf is running on port 80.
• The default InfluxDB admin password is saved in /root/.digitalocean_password.

Quickstart

After the InfluxDB One-Click Droplet is created, you can view the Chronograf setup page immediately by visiting the Droplet’s IP address in your browser.

The first setup prompt requests the InfluxDB username and password. To retrieve this, connect to the Droplet via SSH. You can log into the Droplet as root using either the password emailed to you or with an SSH key, if you added one during creation.

substitute "$Droplet_ip" with the Droplet’s IP address ssh root@$Droplet_ip

Once connected to the Droplet, the InfluxDB username and password can be found in the /root/.digitalocean_password file.

sh sudo cat /root/.digitalocean_password

With the InfluxDB username and password in hand, return to the Chronograf setup page and continue. Kapacitor does not require a username or password.

Once Chronograf is configured, additional guides on how to use the UI can be found in the Chronograf getting started guide.

Configuration details for each component can be found in:

• /etc/telegraf/telegraf.conf and /etc/default/telegraf
• /etc/influxdb/influxdb.conf and /etc/default/influxdb
• /etc/default/chronograf
• /etc/kapacitor/kapacitor.conf and /etc/default/kapacitor

In addition, there are a few customized setup steps that we recommend you take.

Collect more data

By default, Telegraf only collects system metrics for the Droplet. To gather additional metrics, Telegraf can be installed on other remote systems and the url of the InfluxDB output plugin can be set to your Droplet's IP address.

See the Telegraf getting started guide for more details on how to set up Telegraf on other systems.

In some cases, the Telegraf running on your Droplet can also be used to scrape metrics from other systems, such as the Prometheus input, or accept request with metrics from other services, such as the HTTP listener input. Telegraf plugins can be enabled via the Telegraf configuration file at /etc/telegraf/telegraf.conf.

Use the InfluxDB API

The InfluxDB is available on the Droplet's IP address at port 8086. This port is exposed, so you may immediately connect with the InfluxDB CLI.

replace $influxdbusername and $influxdbpassword with valide InfluxDB user credentials influx -username $influxdbusername -password $influxdbpassword

Use the Kapacitor API

Kapacitor is running on the instance and connected to InfluxDB and Chronograf. This setup is usually sufficient. However, access to the Kapacitor API can enable more advanced use cases, like using the Kapacitor CLI to create TICK scripts.

The Kapacitor is available at port 9092, but UFW blocks does not allow external traffic to port 9092 by default. To open the Kapacitor API port, run the following command.

ufw allow 9092/tcp

You can now interact with Kapacitor using the Kapacitor CLI.

Next Steps

To run InfluxDB in production, there are several additional steps you should take, including:

• Follow the security recommendations for each TICK component:
  • InfluxDB security
  • Chronograf security
  • Kapacitor security
