ClickStack Demo Day (17/04/2026) - Improvements to alerting with SQL

Building on the previous week's addition of alerts for Raw SQL line and bar charts, HyperDX now also supports alerts on Raw SQL number charts. The time filter parameter is no longer required when defining an alert: a warning is shown if omitted, but queries without any time dimension are now fully valid. This makes it straightforward to alert on configuration values or system metrics that don't change over time, such as checking that a ClickHouse cluster count equals the expected number.

Several new threshold types have been added: not-equals, is-above, at-most, between, and outside. These give teams much more flexibility in how they express alert conditions beyond simple greater-than comparisons. The alert history is now also surfaced directly inside the tile editor, so when a firing alert links to a specific dashboard tile, users can immediately see the history, understand what triggered it, and acknowledge or silence the alert without leaving the page.
