# General

## Prerequisites

* Docker installed
* Docker Compose installed
* HTTPie installed - <https://httpie.org/>

### Build the required Docker images

* Execute `./build-docker-images.sh`

This will build the following images:

* **Spring Boot Prometheus Demo**: Spring Boot app with custom metrics added

### Configuration

* Please add your own Slack API webhook in `./steps/6-alerting/config.yml`

---

## Step 1: Running Prometheus native

* Explain that Prometheus is a Go application which can just be extracted and run
* Start Prometheus via commandline ./prometheus and show that is running
* Prometheus
  * Navigate to <http://localhost:9090/metrics]> > show the metrics that Prometheus itself is generating
  * Navigate to <http://localhost:9090> > show prometheus webinterface
  * Show Config file (prometheus.yml) -> show Targets
  * Explain that scraping can be done by various ways (Consul, DNS, or dropping in new config file)

## Step 2: Run Prometheus using Docker

* Start Prometheus using docker-compose > dc up
* Show docker-compose.yml > including portmapping

## Step 3: Add host metrics

* Start Prometheus using docker-compose > dc up
* Node exporter
  * Explain Node Exporter
  * Show Node Exporter config inside prometheus.yml > explain scraping
  * Navigate to <http://localhost:9100/metrics>
  * Explain metrics
* Prometheus
  * Navigate to http://localhost:9090
  * Show to to query for metrics using the autocomplete
  * Show how to play using the query language (console & graph)
    * `node_network_receive_bytes`
    * `node_network_receive_bytes{device="eth0"}`
    * `node_network_receive_bytes{device="eth0"}[5m]`
    * `rate(node_network_receive_bytes{device="eth0"}[5m])`

## Step 4: Grafana

* Start Prometheus using docker-compose > dc up
* Grafana
  * Explain Grafana
  * Navigate to http://localhost:3000
  * Login using > admin/admin
  * Add Datasource
  * Create new Dashboard with widget containing graph from memory
    * `node_network_receive_bytes`
    * `node_network_receive_bytes{device="eth0"}`
  * Import dashboard to show the graphs coming from default monitoring of Prometheus
  * Import single server dashboard

## Step 5: Monitor Docker Containers

* Start Prometheus using docker-compose > dc up
* cAdvisor
  * Explain cAdvisor
  * Navigate to http://localhost:8093
  * Show gauges and meters
  * Navigate to http://localhost:8093/metrics
  * Show metrics
* Grafana
  * Navigate to http://localhost:3000
  * Login using > admin/admin
  * Add Datasource
  * Import cAdvisor Dashboard

## Step 6: Alerting

* Start Prometheus using docker-compose > dc up
* Show alert.rules
* Show alert-manager.yml
* Alert Manager
  * Explain the Alert Manager
  * Show alerts http://localhost:9093
* Prometheus
  * Show alerts in http://localhost:9090
* Introduce the Ping container
  * Stop/Start the Ping container -> `docker-compose stop ping`
* View the results in:
  * Slack 
  * Mailslurper: http://localhost:9000

## Step 7: Instrumenting applications

* Start Prometheus using docker-compose > dc up
* SpringBoot App
  * Navigate to http://localhost:8081/metrics
    * Explain that these are the wrong metrics (Spring Boot Actuator)
  * Navigate to http://localhost:8081/prometheus
    * Show the ‘helloworld_requests_total’ counter being 0
  * Navigate to http://localhost:8081/helloworld
    * This increases the counter with 1
  * Navigate to http://localhost:8081/prometheus
    * Show the ‘helloworld_requests_total’ counter being incremented
* Prometheus
  * Show ‘prometheus.yml’ > explain custom metrics path
  * Navigate to http://localhost:9090
  * Show the metric  ‘helloworld_requests_total’ in the web ui

## Step 8: Consul demo

* Start Prometheus using docker-compose > dc up
* Prometheus
  * Show prometheus.yml > explain consul config
  * Navigate to  http://localhost:9090
  * Show targets and see that we are missing the services
* Consul
  * Navigate to http://localhost:8500
  * Show missing services
  * Register the services using ‘register-services-with-consul.sh`
  * Show the services appearing in Consul
* Prometheus
  * Navigate to  http://localhost:9090
  * Show targets and see that the services have appeared
