  - "Splunk uses newline-delimited JSON parsing for search export format"
  - "Kibana uses kbn-xsrf header for saved objects API access"

patterns-established:
  - "Log aggregator source pattern: target exposed instances via base URL override, search API, parse response, apply ciLogKeyPattern"

# Phase 15 Plan 03: Log Aggregator Sources Summary

**Five log aggregator ReconSource implementations (Elasticsearch, Grafana, Sentry, Kibana, Splunk) targeting exposed instances for API key detection in logs, dashboards, and error reports**

## Performance

- **Duration:** 4 min
- **Started:** 2026-04-06T13:27:23Z
- **Completed:** 2026-04-06T13:31:30Z
- **Tasks:** 2
- **Files modified:** 11

## Accomplishments
- Elasticsearch source searches exposed ES instances via POST _search API with query_string
- Kibana source searches saved objects (dashboards, visualizations) via Kibana API with kbn-xsrf header
- Splunk source searches exposed Splunk REST API with newline-delimited JSON response parsing
- Grafana source searches dashboards via /api/search then fetches detail via /api/dashboards/uid
- Sentry source searches issues then fetches events for key detection in error reports
- All 5 sources registered in RegisterAll (67 total sources)

## Task Commits

Each task was committed atomically:

1. **Task 1: Elasticsearch, Kibana, Splunk sources** - `bc63ca1` (feat)
2. **Task 2: Grafana and Sentry sources** - `d02cdcc` (feat)

## Files Created/Modified
- `pkg/recon/sources/elasticsearch.go` - ElasticsearchSource: POST _search, parse hits._source, ciLogKeyPattern
- `pkg/recon/sources/elasticsearch_test.go` - httptest mock for ES _search API
- `pkg/recon/sources/kibana.go` - KibanaSource: GET saved_objects/_find with kbn-xsrf header
- `pkg/recon/sources/kibana_test.go` - httptest mock for Kibana saved objects API
- `pkg/recon/sources/splunk.go` - SplunkSource: GET search/jobs/export, NDJSON parsing
- `pkg/recon/sources/splunk_test.go` - httptest mock for Splunk search export
- `pkg/recon/sources/grafana.go` - GrafanaSource: dashboard search + detail fetch
- `pkg/recon/sources/grafana_test.go` - httptest mock for Grafana search + dashboard APIs
- `pkg/recon/sources/sentry.go` - SentrySource: issues search + events fetch
- `pkg/recon/sources/sentry_test.go` - httptest mock for Sentry issues + events APIs
- `pkg/recon/sources/register.go` - Added 5 log aggregator source registrations

## Decisions Made
- All five sources are credentialless -- they target exposed/misconfigured instances rather than authenticated APIs
- Splunk uses newline-delimited JSON parsing since the search export endpoint returns one JSON object per line
- Kibana requires kbn-xsrf header for CSRF protection bypass on saved objects API
- Response body reads limited to 512KB per response (ES, Kibana, Splunk responses can be large)

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
- Initial Kibana test had API key embedded in a nested JSON-escaped string that didn't match ciLogKeyPattern; fixed test data to use plain attribute value
- Initial Sentry test had invalid JSON in entries field and incorrect event data format; fixed to use proper JSON structure matching ciLogKeyPattern

## User Setup Required

None - no external service configuration required.

## Known Stubs

None - all sources are fully implemented with real API interaction logic.

## Next Phase Readiness
- All 5 log aggregator sources complete and tested
- RegisterAll updated with all Phase 15 sources
- Ready for Phase 15 verification
