Monitoring Vault and Consul

This project uses Vagrant and VirtualBox to spin up a Vault cluster and a Consul cluster on your own machine, with telemetry collected by Telegraf and forwarded to InfluxDB and Grafana for analysis.

Sample Consul Dashboard

Prerequisites

Make sure you have the enterprise binaries for Vault and Consul. The filenames should look similar to this:

consul-enterprise_1.0.5+ent_linux_amd64.zip
vault-enterprise_0.9.3+prem_linux_amd64.zip

Setup

  1. Clone this project from Github.

  2. Place the Consul and Vault binaries into the project folder.

  3. Install the vagrant-hosts plugin: vagrant plugin install vagrant-hosts

  4. Run vagrant up and wait a while.

  5. Log into one of the Vault servers and initialize the cluster:

    $ vagrant ssh vault0
export VAULT_ADDR=http://localhost:8200
vault operator init
vault operator unseal ...

Configuring Grafana

  1. Open http://localhost:3000/ in your browser.
  2. The InfluxDB source will be automatically provisioned
  3. Click the Home menu at the top of the Grafana home page, and select Import dashboard. Browse to the location of vault_cluster_health.json and import it. Do the same for consul_cluster_health.json.

Future Enhancements

  • Provide sample dashboards out of the box.
  • Explain how to send output to CloudWatch, DataDog, and other systems.
  • Demonstrate alerting and proper thresholds.
