Add response envelope middleware to standardize JSON responses as
`{code,data,message}` with consistent business codes across endpoints.
Update Swagger annotations and tests to reflect the new response shape.
BREAKING CHANGE: API responses are now wrapped in a response envelope; clients must read payloads from `data` and handle `code`/`message` fields.
Change the traffic chart API response from bucket-based to series-based
to better support frontend visualization libraries. The new format
provides a shared X-axis and aligned data arrays for each model series.
- Replace `buckets` with `x` and `series` in response
- Implement data alignment and zero-filling for time slots
- Update Swagger documentation including pending definitions
BREAKING CHANGE: The `GET /admin/logs/stats/traffic-chart` response
schema has changed. `buckets` and `models` fields are removed.
Extract ModelMetricsMap as a named type with documentation comments
explaining the map structure and providing examples. Update the
TrafficBucket.Breakdown field to use the new type and enhance the
GetTrafficChart endpoint description with detailed breakdown field
documentation including example usage.
- Fix JSON field alignment in error response and TrafficBucket struct
- Add documentation comment and swagger annotations for Breakdown field
- Remove unnecessary string concatenation spacing in SQL select
Add new endpoint GET /admin/logs/stats/traffic-chart to provide
aggregated traffic metrics grouped by time and model. Features include:
- Time granularity selection (hour/minute)
- Top-N model breakdown with "other" aggregation
- Metrics for request counts and token usage
Includes generated Swagger documentation.
Introduce a comprehensive alert management system for monitoring
system events and notifications.
Changes include:
- Add Alert model with type, severity, status, and metadata fields
- Implement AlertHandler with full CRUD operations (create, list,
get, acknowledge, resolve, dismiss)
- Add alert statistics endpoint for counts by status and severity
- Register Alert model in database auto-migration
- Add minute-level aggregation to log stats (limited to 6-hour range)
Add new admin API endpoints for dashboard metrics and system-wide
realtime statistics:
- Add /admin/dashboard/summary endpoint with aggregated metrics
including requests, tokens, latency, masters, keys, and provider
keys statistics with time period filtering
- Add /admin/realtime endpoint for system-level realtime stats
aggregated across all masters
- Add status filter parameter to ListAPIKeys endpoint
- Add hour grouping option to log stats aggregation
- Update OpenAPI documentation with new endpoints and schemas
Add new response types and parameters for logs API:
- Add GroupedStatsItem and GroupedStatsResponse definitions
- Add ListLogsResponse and LogView definitions for detailed log records
- Add group_by enum parameter (model/day/month) to stats endpoint
- Update endpoint descriptions to clarify response types and request_body inclusion
- Update response schema references to use correct types
Add group_by parameter to /admin/logs/stats endpoint supporting:
- group_by=model: aggregate stats per model with avg latency
- group_by=day: daily aggregation with token counts
- group_by=month: monthly aggregation with token counts
Also include request_body field in admin ListLogs response for
full visibility into logged requests.
