Observability
PromQL Rate Query Builder
Metric, labels, range window, and aggregation, assembled into a syntactically valid rate/irate/increase query - forgetting the range window is a common, silent mistake this avoids.
Label filters (optional)
Rate function
Average per-second rate over the range - smooths spikes, best for alerting.

Call graph, dead code, blast radius and a health score, in about a minute.
