Is your feature request related to a problem? Please describe.

A clear and concise description of what the problem is. such as Ex. I'm always frustrated

There's no method to monitor vatz itself. we need monitoring system for vatz.
Let's start to integrate prometheus from this issue, and we'll handle monitoring for vatz liveness in this issue first.

Describe the solution you'd like| Ex

A clear and concise description of what you want to happen

serve prometheus metrics of liveness for vatz monitoring.

Describe alternatives you've considered

• Can you specify its description how does this is related to issue (Health Checker that notify every VATZ is up and running properly.  #166)?
• Can you separate into two item if it does relate to issue(Health Checker that notify every VATZ is up and running properly.  #166).
  • Health Check: We need to get a discord message for Vatz liveness.
  • Set up prometheus: For Vatz monitoring.

@Choi-Jinhong
Are you going to pass this issue to @heejin-github @kim201212
for monitoring and notification?

@xellos00
This issue and the Health check issue (#166) are different. It is already detached.
@heejin-github and I thought the health check was similar to the alert reminder. Because Health check means vatz can send the INFO alert again. So we tried to develop the health check when @Choi-Jinhong developed the alert reminder.
We thought the Health check is a future requirement.
So we decided to develop the prometheus that we needed right away.
Please let me know if you have any ideas.

Please, update this issue's description.
I guess current description on this issue is wrong info If it is detached with #166.

I said "detached" wrong.
I mean, developing two functions into two different issues.
The two functions are related to each other.

Let's make it clear.

1. Prometheus integration is a big chunk and therefore it has to be divided into sub-issue. Prometheus integration represents VATZ monitoring overall purpose and furthermore for metric data storing.

2. This issue should be separated from Health Checker that notify every VATZ is up and running properly.  #166 because Health Checker that notify every VATZ is up and running properly.  #166 was discussion for "how we get notification message that VATZ is up and running".
   Let's separate it.

Issue's title Prometheus integration is way too vague.
Can you or let @heejin-github update description on this issue to mention for followings
Lets create sub-issue to have full functional Prometheus integration.

• Specify each To do lists for Prometheus integration.
  • Set Prometheus on K8s
  • How to modify or update VATZ config for Prometheus
  • How does monitoring module has to be desgiened
  • Sending metrics data to Prometheus that integrated with notification module
    • which VATZ metric will be delivered at first (suggest aliveness first)
    • How to test it.

Let me know if anyone need explanation for this.

1. Divide into sub-issue.

• Good idea. Let's make sub-issue for integrating prometheus into vatz.
  actually, I just create this issue as a starting point of prometheus integration. I'll update description and title for this issue more clear as you requested, and Please create a new issue for prometheus integration as you thought or designed. then, I'll link it as a parent issue of this.

2. Nobody wanted to develop prometheus and vatz health checker in one issue.

• Health Checker that notify every VATZ is up and running properly.  #166 : vatz health checker
• Prometheus integration #169 : prometheus
  Why do you thought about it was not separated?
  Please let me know anything that if I'm confusing you.

[heejin-github]

Hold this issue until vatz refactoring done.

Hold this issue until vatz refactoring done.

I create this issue as first good issue

Prometheus integration is finished.
