Converting YAML to JSON when configuring RTView

RTView is a new monitoring tool released by IOHK. When configuring or installing RTView, you might need the help of yaml to json converters.

Since LiveView will get removed from future releases, IOHK released a new tool called RTView which helps monitoring your nodes. It is available on GitHub. It is still in the very beginning and therefore don't expect too much of it. What's a bit of a burden is, that in most cases you also have to install apache2 or nginx as reverse proxy to access the statistics of RTView from client machines connected to your network.

After you completed the installation wizzard of RTView you will see a prompt like this:

Great, RTView is ready to run! Its configuration was saved at /home/ada/.config/rt-view.yaml. Press <Enter> to continue...

Now you have to make the following changes in your node's configuration file:

1. Find setupBackends and add TraceForwarderBK in it:

   setupBackends:
     - TraceForwarderBK

2. Find TurnOnLogMetrics and set it to True:

   TurnOnLogMetrics: True

3. Find options -> mapBackends and redirect required metrics to TraceForwarderBK, for example:

   options:
     mapBackends:
       cardano.node.metrics:
         - TraceForwarderBK
       cardano.node.Forge.metrics:
         - TraceForwarderBK

   For more info about supported metrics please read the documentation.

4. Since you have 3 nodes, add following traceForwardTo sections in the root of their configuration files:

   traceForwardTo:
     tag: RemoteSocket
     contents:
       - "IP.OF.YOUR.NODE1"
       - "PORT1"

   traceForwardTo:
     tag: RemoteSocket
     contents:
       - "IP.OF.YOUR.NODE2"
       - "PORT2"

   traceForwardTo:
     tag: RemoteSocket
     contents:
       - "IP.OF.YOUR.NODE3"
       - "PORT3"

After you are done, press <Enter> to run RTView...

In case you wonder how to integrate the above mentioned configs to your config json file, a simple yaml to json converter might help. There are plenty of them in the web. Here's one: https://dataconverter.curiousconcept.com/ . Just paste your code in there and convert it from yaml to json. I hope this makes things easier for you!

Have a great start with RTView!

Gottfried Wilhelm Leibniz: The Last Of The Polymath Geniuses
I wrote about the great genius Geralomo Cardano in an earlier post. He was what we call a "Polymath", which was a common description of early scientists and mathematicians before the concept of "academic specialization" became the normal path to follow. Gottfried Wilhelm Leibniz is considered to be one of the last great Polymaths, and for good reason.

A.T. and A.I.
Anyone who has studied the history of computer science and cryptography will be familiar with the terms, "Turing Complete", and "Turing Machine". These terms were coined due to the influence Alan Turing had before computers as we know them existed. His brilliant solution to breaking the Nazi's Enigma coding machine during WWII has been well documented in multiple books and films. However, just before his untimely death in 1954 at age 42, (69 years ago) he correctly foretold the potential of what we now call, "AI", and the disruption it would cause in our own time.

Charles Hoskinson
Everything relating to Cardano can be traced back to its co-founders: Charles Hoskinson and Jeremy Wood. I highlighted Jeremy Wood in one of my recent posts, and now I will attempt to illuminate some of the important facts about Charles Hoskinson and his broad sweeping vision for Cardano and the world.

Voltaire
The Vasil hard fork has ushered us into “Basho”, the next-to-last era of the Cardano Roadmap. Soon we will enter into the final era, "Voltaire", planned from the very beginning of Cardano’s journey and development. This post is about Voltaire himself, one of the most advanced intellects of all time. His influence on the way we look at the world and the way we think about our world cannot be overstated. However, the scope of his writings and pursuits combined with the many places he lived during his lifetime cannot be covered in a blog post. Therefore I am touching upon the more important points of his life and work, leaving a deeper investigation up to you, the reader.
