Census: all 5 provisioned dashboards, 56 targets, every expression
re-evaluated against the live Prometheus/Loki with template vars expanded
(queries must run from the host: both APIs bind 127.0.0.1; from the dev box
that is connection-refused, which is NOT a dashboard defect).
- host-system 'Load 5m / core' was STRUCTURALLY EMPTY: bare '/' drops
non-matching pairs and the right side collapses to {job} while the left
carries {job,instance} -> 0 series forever. Fixed with / on(job); proven
live (2 series).
- containers 'Memory vs limit (%)' was STRUCTURALLY EMPTY: every
container_spec_memory_limit_bytes on this fleet is 0 (no cgroup limits),
so the '> 0' filter can never match. Rewritten to share-of-host-total via
label_replace join of the node exporter's MemTotal by host (the parens
form is a PromQL parse error: nothing may follow group_left); 62 series
live. Panel unit percentunit kept -> expression returns a fraction.
- llm-fleet 'Firing fleet alerts' is legitimately empty when healthy
(ALERTS carries only firing/pending series); description now says so,
per the Stale Signal rule that 0-series-on-ALERTS is not a defect.
logs-overview and observability: all targets already returning data.
