ClickStack Demo Day (2026-09-04) - Alert names and tags

Alerts can now carry their own name and tags. The alert form on a dashboard tile or saved search has a name input and a tag input, and a new alert defaults to the chart or saved search name and inherits the tags from the dashboard or saved search it belongs to. Those names are what the alerts page shows, and they're what you search and filter by. Alerts already in the database with no name set still derive one from the saved search or dashboard they reference, so nothing looks empty in the meantime. The field is called displayName rather than name because the existing name can be a Handlebars template, and production data does contain templates. Showing an unrendered template on the alerts page would be worse than deriving a name. This is groundwork. The goal is paginating the alerts page while still supporting search and filter by tag, which needs name and tags on the alert document itself rather than a join against the dashboard and saved search collections. The pagination isn't done yet. Part of the ClickStack Demo Day series. See the full post at https://clickhouse.com/docs/use-cases/observability/clickstack/demo-days/2026/2026-09-04
