Drop the traces dashboard, keep the datasource wiring
The dashboard reimplemented, less well, what Explore already does: its search panel had no TraceQL query builder and no autocompletion, and its service dependency table replaced an interactive node graph with a list. Searching and exploring traces belongs in Explore. The datasource correlations this work also fixed are kept — they are what was actually missing, and they apply in Explore exactly as they would in a dashboard.

### Distributed tracing
|
||||
|
||||
`obs-traces` searches traces with TraceQL, assembled from a service selector, a
|
||||
minimum duration, a status, and a free-text field for conditions the selectors
|
||||
do not cover. The status and free-text variables hold TraceQL *fragments* rather
|
||||
than values, so an empty one contributes nothing and the surrounding query stays
|
||||
valid — "no filter" is the default rather than a special case.
|
||||
Traces are searched and explored in **Explore**, on the Tempo datasource, not
|
||||
from a dashboard. Explore's TraceQL query builder, autocompletion, trace view
|
||||
and interactive service graph have no dashboard equivalent worth maintaining —
|
||||
a dashboard search panel is a worse copy of a tool that already exists.
|
||||
|
||||
Opening a trace gives the waterfall, every span's attributes and events, and
|
||||
from a span its logs and its RED metrics. The rest of the dashboard is the
|
||||
aggregate view: rate, errors and latency percentiles from the span metrics
|
||||
Tempo's own `metrics_generator` derives from the traces, the slowest and most
|
||||
failing operations by span name, and the service-to-service edges Tempo infers.
|
||||
|
||||
Span name rather than endpoint is the unit worth looking at: a slow database
|
||||
statement surfaces next to a slow HTTP handler, which is what tracing buys over
|
||||
plain HTTP metrics.
|
||||
|
||||
The interactive node graph stays in Explore — `serviceMap` is a query type
|
||||
Grafana's frontend assembles and it returns nothing through the dashboard query
|
||||
API, so the dashboard shows the same edges as a table instead.
|
||||
What the repository does own is the datasource wiring, which applies in Explore
|
||||
exactly as it would in a dashboard.

#### Span-to-metrics correlation

`tracesToMetrics` had no queries defined and rendered a bare datasource link. It

now carries rate, error-rate and p95 queries against `traces_spanmetrics_*`,

scoped to the span's own service.

Those span metrics are worth knowing about independently: Tempo's

`metrics_generator` derives them from the traces and remote-writes them to

Prometheus, keyed by `service` and `span_name`. They measure the *span*, so a

slow database statement appears next to a slow HTTP handler — a granularity the

gateway and per-application dashboards, which measure HTTP, do not have.
