Trace Retention and Pruning Manager

Module

Scanner

Status

IMPLEMENTED

Description

Manages runtime trace lifecycle with configurable retention periods (default 30 days), automatic pruning of old traces while preserving those referenced by active slices, trace aggregation, and storage quota enforcement.

Implementation Details

  • Trace Retention Manager:
    • src/Scanner/__Libraries/StellaOps.Scanner.Runtime/Retention/TraceRetentionManager.cs - TraceRetentionManager managing runtime trace lifecycle with configurable retention periods (default 30 days), automatic pruning of expired traces while preserving those referenced by active reachability slices, trace aggregation, and storage quota enforcement

E2E Test Plan

  • Configure a 30-day retention period and verify traces older than 30 days are automatically pruned
  • Verify traces referenced by active reachability slices are preserved even if they exceed the retention period
  • Verify trace aggregation combines repeated observations into summary records before pruning individual traces
  • Configure a storage quota and verify the retention manager prunes oldest traces when quota is exceeded
  • Verify pruning is idempotent (running multiple times produces the same result)
  • Verify retention configuration can be updated without data loss
