pub static CTPROF_METRICS: &[CtprofMetricDef]Expand description
Registry of per-thread metrics. Order here is the default display order for rows that have no numeric delta to sort by (ties fall back to registry order). Names are the ASCII short-form used in capture code; long-form display is the same — no translation layer.
PSI is intentionally not in this registry. Each
AggRule variant’s accessor takes &ThreadState and
returns a crate::metric_types newtype (or a primitive
the dispatch coerces via to_string() for ModeChar /
ModeBool); only per-thread data fits that signature, while
Pressure Stall Information is per-snapshot (host-level) and
per-cgroup. PSI surfaces in dedicated secondary tables
under “## Host pressure / …” and “## Pressure / …”
headers, rendered by write_diff / write_show directly
rather than via AggRule. See Psi / PsiResource /
PsiHalf for the data model.
