add get_trace_activity to tool catalog
update executor to have tool implementations and reuse in enterprise

Summary by CodeRabbit

  • New Features
    • Added trace activity analysis with time bucketing, grouping, and span or trace counts.
    • Event sampling supports explicit time bounds and prioritizes observability fields.
    • Dashboard listings can be filtered by title and tags.
    • Time ranges support local time zones, relative durations, and explicit date ranges.
  • Improvements
    • Dataset discovery checks access and activity, ranks active datasets, and returns relevant candidates when a match is uncertain.
    • Dataset resolution supports telemetry-type filters and result limits.
    • Queries and tabular results are limited to 10 columns and 500 rows; only a single supported SELECT is accepted.
    • Log-context requests require an exact log, body, or message value and default to a five-minute context window.

Walkthrough

The OSS tool catalog and executor add trace activity and update SQL validation, dataset discovery and resolution, time-range handling, event sampling, log context, dashboard filtering, and tool dispatch. The HTTP query-context handler delegates authorized requests to an extracted helper.

Changes

OSS observability tools

Layer / File(s) Summary
Query safety and dataset resolution
Cargo.toml, src/tool_executor.rs, src/tool_catalog.rs
SQL validation and tabular responses now enforce query, row, and column limits. Dataset resolution uses visible datasets, telemetry types, and ranked candidates. Time ranges support IANA timezones and relative or explicit bounds. Catalog validation adds oneOf support and tests dataset-resolution arguments.
Dataset activity discovery
src/tool_executor.rs
Discovery validates the requested time range and telemetry type, then checks eligible datasets concurrently. Its response includes active datasets, event counts, and unavailable-dataset details.
Bounded event sampling and log context
src/tool_catalog.rs, src/tool_executor.rs, src/handlers/http/query_context.rs
sample_events accepts explicit time bounds and selects preferred observability fields. Log-context requests require an anchor value and use the authorized context-query path. Results are bounded by row and field limits.
Trace activity query
src/tool_catalog.rs, src/tool_executor.rs
The read catalog adds get_trace_activity as an expensive read. The executor validates grouping fields, filters, and bucket count, then returns distinct span and trace counts with query metadata and rows.
OSS dispatch and dashboard filtering
src/tool_executor.rs
Public OSS execution validates tool arguments before dispatch, and the registry endpoint uses this validated path. Dashboard listing filters titles and tags when a query is supplied. Tool context headers are named query headers.

Review comments at @src/tool_executor.rs:
- Around line 122-128: Update bounded_tool_sql so a trailing line comment cannot
consume the wrapper’s closing parenthesis, alias, or LIMIT; preserve the
validated query behavior while ensuring the generated bounded SQL remains
parseable.
- Around line 693-700: Update the column selection logic that builds selected
from preferred fields so it then appends schema fields not already selected
until selected reaches MAX_TOOL_COLUMNS. Preserve preferred-field ordering and
avoid duplicates, so custom-schema datasets retain their other fields.
- Around line 855-856: Update get_log_context to retain and use the request
built by log_context_request: match rows using its anchor values and apply its
contextWindow and conditions. Update the corresponding catalog schema so the
anchor fields’ requiredness matches the executor’s behavior.
- Around line 840-849: Update the field selection around PREFERRED_FIELDS so it
keeps preferred fields first, then fills the remaining MAX_TOOL_COLUMNS slots
with other object keys not already selected; preserve the existing object.retain
projection using the completed selection.
- Line 308: Update the resolve_dataset schema so limit and telemetryType are
accepted by public callers, and update resolve_dataset_candidates’ datasets
payload to include each dataset’s actual telemetry type. Ensure telemetryType
filtering uses that value rather than inferring the type from the dataset name.

180-206: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Load dataset metadata only when filtering by telemetry type.

resolve_dataset builds the full catalog before resolving the request. For datasets not already in memory, check_or_load_stream can load metadata and schema from object storage. The current loop awaits this work serially, so latency can grow with the number of visible datasets.

resolve_dataset_candidates uses telemetryType only when the argument contains a string value. Otherwise, name-only catalog entries are sufficient. Load metadata concurrently only when that filter is present.
