Coffee-Factory

For more information about the project see:

http://www.apamacommunity.com/the-coffee-factory/

How to set up the project:

Designer:

• Clone the repository to a desired location
• If you do not have Designer on your machine, use this link to download it: http://www.apamacommunity.com/downloads/ (under Full version)
• Open the Project via Designer

Prometheus:

• Go to https://prometheus.io/download/ and download Prometheus (should be on the very top) by choosing the file that corresponds to your OS.

• Install Prometheus to a suitable directory.

• Go to the folder which contains the installation and open the prometheus.yml file by right clicking on it and select a suitable text reader(notepad might not work), for example, I use Notepad++ to open it. Another thing you can do to open the file is: drag and drop the prometheus.yml file onto Designer.

• Once opened, at the very bottom make sure it looks like this:

  static_configs:

  • targets: ['localhost:15903']

  You will have to just set the 'targets' to ['localhost:15903'];

Grafana:

Firstly, follow this link: https://grafana.com/docs/guides/getting_started/

• Once you do the first two steps i.e. installation guide & logging in for the first time, open the folder 'Grafana' in your Designer project and in it you would see a grafana.json file, copy the content of the file.

• Go to Grafana, click 'Create' (the plus button at the top left corner) and then click 'dashboard settings' (on top right) which will take you to another page.

• In that page click JSON model, paste here what you copied from the grafana.json file in Designer project.

• Scroll to the top of the JSON model text and change the value of the 'id' to be 'null' (without quotes);

• Click 'Save Changes'.

• Now go to 'Configuration'

• Click on the Prometheus field (should be in the center of the screen);

• Update the URL to: http://localhost:9090

• Update the Scrape Interval to 1s

---

To start the project:

• In Designer, right click on the project folder.
• Select 'Run as'
• Select 'Apama Application'

In about couple of seconds the live data will be displayed on Grafana.

And if you would like to send a bad event go to Designer. Find the coffee project and start it if it is not on. Open the events folder and you will see a BadEvent.evt file. Right-click on it and select Apama -> Send Events. Now observe how Apama will handle the bad event on Grafana.
