[🐛 Bug]: threshold and other comparisons allow numbers, but validation expects only strings

[AyalaEl]

Describe the bug
threshold and other comparisons should allow numbers (according to documentation and examples), but validation expects only strings

To Reproduce

1. Opened the "VictoriaMetrics Threshold Monitor" template
2. Validation (before changing anything):

Expected behavior
accepts numbers

You’re right—according to both the documentation and the VictoriaMetrics alert examples, threshold comparisons should accept numbers, not just strings (example, example). The backend logic for threshold conditions is designed to handle both numeric strings and floats, so numbers should work as expected (source).

The validation error you’re seeing is likely due to a mismatch between the schema validation (which may be too strict about types) and the intended backend logic. The UI itself does not enforce string-only input for thresholds; it passes your input to the backend, where the CEL validator or schema might be enforcing string types (source).

There are no recent changes or open issues directly addressing this, so this looks like a backend validation/schema bug rather than a UI or documentation issue. The backend validation should be updated to accept both numbers and numeric strings for thresholds to match the documented and expected behavior.

To reply, just mention @dosu.
