The per-application dashboards answer "how is this component behaving". This
one answers "where did that string come from", across every source at once, and
is kept separate so neither has to compromise for the other.
Scope is a curated preset rather than a free namespace picker: the cluster
carries 48 log sources and most are infrastructure noise. The presets are job
regexes over the <namespace>/<container> label Alloy sets — except kong-audit,
which Fluent Bit ships with no namespace at all. That mismatch between the two
collection paths is the reason a single naive selector cannot span both, and
why the presets spell the sources out.
The search term is injected inside LogQL backticks, a raw string, so a quote
typed in the box cannot break the query; an empty box yields `(?i)`, a valid
regex matching every line, which makes "no search" the default rather than a
special case. The four stat panels carry `or vector(0)` so an empty result
reads as 0 rather than "No data" — on a search box, finding nothing is an
answer, not a failure.
Two deliberate omissions. No per-format parsing: the Message column holds the
line as emitted, because the five formats agree on nothing and that is what the
per-application dashboards are for. And the level filter is partial by nature —
roughly 40% of lines are `unknown`, since access lines and Kong records carry
no severity for Loki to infer.
