Waiting for the test data to be generated

We need to generate some test data for Prometheus which can take a couple of minutes.
Once the environment is set up, lets see how to access it.

Accessing the Prometheus Console

• The Prometheus console can be accessed using the following url:
  http://prometheus-demo-route-myproject.[[HOST_SUBDOMAIN]]-80-[[KATACODA_HOST]].environments.katacoda.com/

  

• To check if the test data was generated successfully, go to the following url:
  http://prometheus-demo-route-myproject.[[HOST_SUBDOMAIN]]-80-[[KATACODA_HOST]].environments.katacoda.com/graph?g0.range_input=12h&g0.expr=test&g0.tab=0

• The above link will query the Prometheus instance for a metric called test for the past 12 hours and if the data was generated successfully your Prometheus console should look like this:

Accessing the Jupyter Notebooks Environment

• The Jupyter environment with the workshop notebooks is available here:
  https://prometheus-anomaly-detection-workshop-myproject.[[HOST_SUBDOMAIN]]-80-[[KATACODA_HOST]].environments.katacoda.com/

• You might see a warning like in the image below, this is because we don't generate valid ssl certificates for all our routes. You can click on Advanced... and then click on Accept the Risk and Continue to continue to the Jupyter environment.

  

• You will need a password to access the environment.
  The password is secret
  

• There are 2 notebooks available in the Jupyter environment:

  1. (Exercises) Introduction_Prometheus_API_Client.ipynb - In this notebook you will explore and solve few exercises on using the Prometheus API client.
  2. (Solutions) Introduction_Prometheus_API_Client.ipynb - You will find the solutions to the exercises in this notebook.
     
     

  

• The idea behind this scenario is to work through the Exercises notebook and only check the solutions notebook when you need help.

That's it, once you are done with the notebooks you have finished this scenario.
The next step will just show you how to access the backend for this scenario, you can safely skip it.

Accessing the OpenShift Console

You don't need to access the OpenShift Console for the purposes of this workshop.
But if you want to look at what's going on under the hood, you can follow the instructions below:

To access the OpenShift console:

• Click on the Dashboard tab in the workshop dashboard. You will be presented with the OpenShift login screen.

  

  For the credentials, enter:

  • Username: developer
  • Password: developer

Once you have logged in, you should be shown the list of projects you have access to. A project called myproject is where this workshop is deployed.

• In this project you should be able to see two different applications that have been deployed.
  

  • The prometheus-anomaly-detection-workshop application is the Jupyter notebook environment.

  • The prometheus-demo application is the Prometheus instance with the test metric data.

While playing around the backend keep in mind that this environment will only be active for 1 hour.
