@neal-shah I've deployed this to Azure, looks great, wanted to provide some feedback.

1. High level explanation to users on function of Prometheus, Grafana, Elk would be optimal.
2. Advice on deploying to an Azure Ubuntu Instance and how to set up public DNS name e.g.

Grafana http://hostname.eastus.cloudapp.azure.com:3000/
Kibana http://hostname.eastus.cloudapp.azure.com:5601/

3. Advice on ports that need to be opened on NSG in Azure for VM

4. List pre-reqs and versions of deployment needed in an Azure Ubuntu e.g.

Java

openjdk version "1.8.0_252"
OpenJDK Runtime Environment (Zulu 8.46.0.19-CA-linux64) (build 1.8.0_252-b14)
OpenJDK 64-Bit Server VM (Zulu 8.46.0.19-CA-linux64) (build 25.252-b14, mixed mode)

Docker
sudo apt install docker
sudo apt install docker-compose
sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io

5. Explain to the users that the docker compose file is structured such that containers start up with the specified ports available for both internal and external access which is very useful.

6. Provide additional guidance on the Kibana available fields.

7. Maybe include instructions on how to download an RPC client to Desktop and connect via RPC to one of the nodes e.g. Corda Tools Explorer for submitting transactions via RPC to Party A and Party B which user can then view in Kibana.

Several issues:

• Nodes not able to write H2 db to the persistence folder
• Filebeat permissions to the config file is failing
• ELK requires sudo sysctl -w vm.max_map_count=262144 to be set

Docker needs at least 8GB of RAM assigned in order to run this example. It would be good to have this as a pre-requisite at the start of the doc.
