Frequently asked questions
Does this connect to Prometheus?
The complete core workflow is local and works from pasted or opened files without a server.
Is the PromQL engine complete?
No. It validates broadly and executes a clearly documented practical snapshot subset; production Prometheus remains authoritative.
What does cardinality mean here?
It is the number of unique series and label values visible in the imported snapshot, not the full production database.
Does a firing result include the alert for duration?
The tool reports expression matches and configuration; a snapshot cannot prove continuous truth across the full for duration.
