add yellow color option for non critical checks

[simo222]

Describe the feature request

at the moment gatus has two colors. red and green. could you also add option for yellow color.

a possible option.

  - name: tst-app
    group: not-imortant
    url: https://localhost:8080/healthz
    interval: 60s
    color: yellow
    conditions:
      - "[STATUS] == 200"
      - "[BODY] == pat(*ok*)"
      

for custom check could be something like

 ` curl -X POST -H "Authorization: Bearer 123456" "http://127.0.0.1:8080/api/v1/endpoints/core_ext-ep-test/external?success=warning&error=xxxx"
  `
  success=warning could show a yellow color in gatus 

Why do you personally want this feature to be implemented?

some application are not very critical .

If I understand correctly, you'd want all failed checks for that endpoint to show up as yellow, correct?

[simo222]

For external endpoint i want to choose which color i send

For example disk alert. . If 80%full i want to send yellow . If 90%full i want to send red

For endpoint you are right. All yellow.
However i could think of some usee cases. For example if certificate expires in one week make it yellow. If one day make it red

I think also good to consider that group color which needs some logic. If there is one yellow check in the group, then make the group color yellow. If there is one check red, then make it red. Red has more prio than yellow

I used in the past this. I had this feature

To be honest, if we're going to make the error color customizable, we may as well allow more customization than just yellow. Either way, I think it's a great idea.

Can I take this up ?

Hi, Is anybody working on this at the moment? :) I raised #839 which is exactly like this and I think this is a wonderful idea!!

It would be great if each test could have some kind of criticality. In my use case, it would be great to have a different color when an endpoint has a higher latency than usual because it is less critical than an endpoint not working at all.
