Building a Simple Prometheus Monitoring Environment with Ansible + Vagrant

Overview

This takes the tutorial from Getting Started with Prometheus
and makes it easy to set up with Ansible.

The other day, on June 14, 2016,
I attended Prometheus Casual Talks #1 at LINE Corporation,
and since I wanted to review what I’d learned,
I put together this setup guide.

What is Prometheus

It’s a recently popular pull-based monitoring/alerting tool that supports query filtering and integrates with the likes of Grafana.

Architecture

Prometheus Server × 1
Prometheus Client × 2

Environment

CentOS 6.5
Prometheus Server 0.20.0
Supervisor 3.3.0
Go 1.6.2
Ansibl 2.1.0.0
Vagrant 1.8.1
MacOSX 10.11.5

Prerequisites

Please install the following tools beforehand.

VirtualBox
Vagrant
Ansible

Usage

1. Clone the git repository

[https://github.com/kenzo0107/Vagrant-Prometheus]

1	$ git clone https://github.com/kenzo0107/Vagrant-Prometheus

2. Start the Vagrant VMs

1 2	$ cd Vagrant-Prometheus $ vagrant up

3 nodes running!

1 node: Prometheus Server
- 192.168.11.30
other 2 nodes: Prometheus Client Server
- 192.168.33.31
- 192.168.33.32

3. Add ssh.config

1	$ vagrant ssh-config > ssh.config

4. ping connectivity test

$ ansible default -m ping

server | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
client1 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}
client2 | SUCCESS => {
    "changed": false,
    "ping": "pong"
}

ok, success.

5. Configure PrometheusClient on the 2 nodes

1	$ ansible-playbook set_clients_prometheus.yml

6. Verify PrometheusClient is running

Access the servers running PrometheusClient below
and confirm that they are up.

If you see something like the following, it succeeded.

7. Configure PrometheusServer

1	$ ansible-playbook set_server_prometheus.yml

8. Verify PrometheusServer

Access http://192.168.33.30:9090

If you see something like the following, it succeeded.

I hope this is at least a little bit of help!
Go ahead and tinker with it to your heart’s content!

That’s all.
