Implement the HAProxy log analyzer which you've written in bash and see the difference print the output logs to a file which is accessible by /log through Nginx

Through python grab system metrics such as - CPU , RAM & Disk usage- make a graph out of those metrics using plotly library which is accessible by /charts through Nginx save those metrics in redis DB

do all configurations through ansible -as much as possible-

In stage 2 we utilize redis library to connect to the redis DB and we used sorted sets which are associated with score, that is used in order to take the sorted set ordered, from the smallest to the greatest score. While members are unique, scores may be repeated. With sorted sets you can add, remove, or update elements in a very fast way. And sorted sets here are given a timestamp a label-which is cpu , memory or disk- and the value. These values are stored for 30min and then they will be deleted to free memory space. And finally draw graphs using plotly

And finally in stage 3 reside the Nginx image file.

Like last time, On master node you need to create an ssh key and populate it because Ansible do coordinate all other nodes through ssh

ssh-keygen
ssh-copy-id [server ip's]

Install ansible on your master node:

yum install epel-release
sudo yum update
sudo yum install ansible

Change DNS on master node to shecan DNS by editing /etc/resolve.conf and adding below line on top of it

nameserver 178.22.122.100

Download needed modules for ansible to be able to run the playbook & finally run your playbook:

ansible-galaxy collection install community.general
ansible-playbool playbook.yml

the final project will look like below:
