Lab 3 - Review Results

Access Grafana

1. Within the lab components screen, select Access on the Jumphost, and choose Grafana from the dropdown.

   Launch Grafana and logon with the credentials below:

   username: admin

   password: grafana

   

2. Once logged in, navigate to Dashboards –> Services –> Distributed Host Stats via MQTT

   On the Dashboard, you should see one chart for each Customer Edge region we deployed to. We haven’t sent any data yet, so the charts will be empty.

   Note

   The Green icons in the image will be an indicator that the connection to the MQTT broker was successful.

Let’s Publish Some Data

Now that we have the Grafana dashboard setup, we can start publishing data to the MQTT brokers.

From the Web Shell, run the following command to start the data publisher:

cd ~/caaslab
./systemstats2mqtt.sh

The script will start publishing data to the MQTT brokers in each region. After a few minutes, you should start to see data on the Grafana dashboard.

In a couple minutes your Web Shell will look like this:

Review the Data

Navigate back to the Grafana dashboard and you should see data populating the charts. If you wait 5 minutes, your dashboard will look something like this:

Conclusion Upon successful completion your Grafana dashboard should be populated with near real-time system metrics from your lab’s jumpbox.

In a real-world scenario could leverage Regional Edge load balancers automatically route the data to the nearest healthy MQTT broker.
