pub fn compute_stats(
graph: &Graph,
stat_keys: &[String],
) -> BTreeMap<String, AttrValue>Expand description
Compute the mean of each metric in stat_keys over all internal (file)
nodes. Zero/missing values are excluded (historical behaviour); a metric is
emitted only when its average is positive. The key set is data-driven — the
caller passes the tier-2 stat metrics (from the registry) plus coupling keys —
so this module names no metric.
