Before	After

How to set up and validate locally

1. Enable feature flag observability_features

2. Ensure you have a working Ultimate licence.

3. Create a new group, and project within it.

4. Create a new issue by visiting the issues/new page with the correct urlencoded payload. Here's an example:

   /new?observability_metric_details={"fullUrl"%3A"http%3A%2F%2Fgdk.test%3A3000%2Fgitlab-org%2Fgitlab-test%2F-%2Fmetrics%2Fapp.ads.ad_requests%3Ftype%3DSum%26date_range%3D1h%26group_by_fn%3Dsum%26group_by_attrs[]%3Dapp.ads.ad_request_type%26group_by_attrs[]%3Dapp.ads.ad_response_type"%2C"name"%3A"app.ads.ad_requests"%2C"type"%3A"Sum"%2C"dimensions"%3A["app.ads.ad_request_type"%2C"app.ads.ad_response_type"]%2C"timeframe"%3A["2024-07-2504%3A47%3A00UTC"%2C"2024-07-2505%3A47%3A00UTC"]%2C"latestValues"%3A["app.ads.ad_request_type%3ANOT_TARGETED%2Capp.ads.ad_response_type%3ARANDOM%3A281.000"%2C"app.ads.ad_request_type%3ATARGETED%2Capp.ads.ad_response_type%3ATARGETED%3A1387.000"%2C"app.ads.ad_request_type%3ATARGETED%2Capp.ads.ad_response_type%3ARANDOM%3A287.000"]}

   Note: This issue will add a button that generates and links that payload automatically.

5. Ensure that the issue is prefilled with a title that looks like Issue created from app.ads.ad_requests

6. Ensure that the issue is prefilled with the description

   [Metric details](http://gdk.test:3000/gitlab-org/gitlab-test/-/metrics/app.ads.ad_requests?type=Sum&date_range=1h&group_by_fn=sum&group_by_attrs[]=app.ads.ad_request_type&group_by_attrs[]=app.ads.ad_response_type) \
   Name: `app.ads.ad_requests` \
   Type: `Sum` \
   Timeframe: `2024-07-2504:47:00UTC - 2024-07-2505:47:00UTC`

@mwoolf I still believe that this 'create title/description' should live somewhere else so we have better separation of concerns. And use issue[title] and issue[description] parameters (with some ?o11y_isssue=true flag.

I have one comment for the specs. The code itself looks good.
