Install Demonstration

Howto

First of all, clone the giropopos-monitoring repo:

# git clone https://github.com/badtuxx/giropops-monitoring.git

Install Docker and create Swarm cluster

# curl -fsSL https://get.docker.com | sh
# docker swarm init

Install Netdata:

# bash <(curl -Ss https://my-netdata.io/kickstart.sh)

Setting Netdata Exporter configuration in Prometheus:

# vim conf/prometheus/prometheus.yml
...
- job_name: 'netdata'
    metrics_path: '/api/v1/allmetrics'
    params:
      format: [prometheus]
    honor_labels: true
    scrape_interval: 5s
    static_configs:
         - targets: ['YOUR_IP:19999']

Get Rocket.Chat Incoming WebHook

Deploy giropops stack, only to get the WebHook

# docker stack deploy -c docker-compose.yml giropops

Access YOUR_IP:3080 and create your account
Login with your user and go to: Administration => Integrations => New Integration => Incoming WebHook
Set "Enabled" and "Script Enabled" to "True"
Set all channels, icons, etc. as you need
Paste contents of rocketchat/incoming-webhook.js into Script field.
Create Integration. You will see some values appear. Copy WebHook URL and proceed to "Integration between Rocket.Chat and AlertManager" section.
Remove giropops stack

# docker stack rm giropops

Rocket.Chat Docs

Integration between Rocket.Chat and AlertManager

# vim conf/alertmanager/config.yml

route:
    repeat_interval: 30m
    group_interval: 30m
    receiver: 'rocketchat'

receivers:
    - name: 'rocketchat'
      webhook_configs:
          - send_resolved: false
            # copy below the WEBHOOK that you create before
            url: '${WEBHOOK_URL}'

Deploy Stack with Docker Swarm

Execute deploy to create the stack of giropops-monitoring:

# docker stack deploy -c docker-compose.yml giropops

Creating network giropops_backend
Creating network giropops_frontend
Creating network giropops_default
Creating service giropops_prometheus
Creating service giropops_node-exporter
Creating service giropops_alertmanager
Creating service giropops_cadvisor
Creating service giropops_grafana
Creating service giropops_rocketchat
Creating service giropops_mongo
Creating service giropops_mongo-init-replica

Verify if services are ok:

# docker service ls

PS: Don't worry why giropops_mongo-init-replica service is down, it only executes one time to initialize the replica set. It will not stay running.

Remember that RocketChat endpoints and payloads are identical to Slack's, so if you wanna set Grafana alerts, just select a slack alert and give it a RocketChat incoming webhook URL, with no script needed.

Test if your alerts are ok:

# docker service rm giropops_node-exporter

Wait some seconds and you will see the integration works fine! Prometheus alerting the AlertManager that alert the Slack that shows it to you! It's so easy and that simple! :D

Of course, create new alerts on Prometheus:

# vim conf/prometheus/alert.rules

Ahhhh, Help us to improve it!
