Database cleanup:
- Converted spawn_events to a TimescaleDB hypertable with 7-day retention.
Previously a regular table growing unbounded — had reached 482M rows/66GB
from June 2025. Manual migration copied last 7 days (12M rows) to a new
hypertable, swapped names, and dropped the old table.
Result: DB shrunk from 77GB → 12GB.
- Dropped server_health_checks table entirely. It was write-only (850K rows,
134MB) — only current state in server_status is actually read. Eliminated
the insert from monitor_server_health().
Telemetry handler cleanup:
- Removed 4 per-message INFO log lines (TELEMETRY_RECEIVED, DB_WRITE_ATTEMPT,
DB_WRITE_SUCCESS, PROCESSING_COMPLETE). At 60+ chars × every 2s = hundreds
of log lines/sec. Replaced with single SLOW_* warnings above 500ms/1000ms
thresholds.
- Removed redundant pool-size introspection (try/except + hasattr) on every
telemetry message — useless noise in the hot path.
- Removed debug cache-miss and kill-delta logs.
Log level:
- docker-compose.yml: dereth-tracker LOG_LEVEL DEBUG → INFO (was dumping
entire inventory_delta JSON payloads for every item update).
- inventory-service LOG_LEVEL DEBUG → INFO.
