docker-compose-telegraf-influxdb-grafana

Multi-container Docker app built from the following services:

• Telegraf - agent for collecting, processing, aggregating, and writing metrics.
• InfluxDB - time series database
• Chronograf - admin UI for InfluxDB
• Grafana - visualization UI for InfluxDB

Useful for quickly setting up a Model Driven Telemetry stack.

Quick Start

To start the app:

1. Install docker-compose on the docker host.
2. Clone this repo on the docker host.
3. Optionally, change default credentials or Grafana provisioning.
4. Run the following command from the root of the cloned repo:

docker-compose up -d

To stop the app:

1. Run the following command from the root of the cloned repo:

docker-compose down

Ports

The services in the app run on the following ports:

Host Port	Service
3000	Grafana
8086	InfluxDB
57000, 57100, 57500	Telegraf
127.0.0.1:8888	Chronograf

Note that Chronograf does not support username/password authentication. Anyone who can connect to the service has full admin access. Consequently, the service is not publically exposed and can only be access via the loopback interface on the same machine that runs docker.

If docker is running on a remote machine that supports SSH, use the following command to setup an SSH tunnel to securely access Chronograf by forwarding port 8888 on the remote machine to port 8888 on the local machine:

ssh [options] <user>@<docker-host> -L 8888:localhost:8888 -N

Volumes

No volume is created. Data is lost when the app is stopped.

Users

The app creates two admin users - one for InfluxDB and one for Grafana. By default, the username and password of both accounts is admin. To override the default credentials, set the following environment variables before starting the app:

• INFLUXDB_USERNAME
• INFLUXDB_PASSWORD
• GRAFANA_USERNAME
• GRAFANA_PASSWORD

Database

The app creates a default InfluxDB database called telemetry.

Data Sources

The app creates a Grafana data source called InfluxDB that's connected to the default IndfluxDB database (e.g. telemetry).

To provision additional data sources, see the Grafana documentation and add a config file to ./grafana-provisioning/datasources/ before starting the app.

Dashboards

By default, the app does not create any Grafana dashboards. An example dashboard that's configured to work with artillery-plugin-influxdb is located at ./grafana-provisioning/dashboards/artillery.json.example. To use this dashboard, rename it to artillery.json.

To provision additional dashboards, see the Grafana documentation and add a config file to ./grafana-provisioning/dashboards/ before starting the app.
