Jira link: https://specterops.atlassian.net/browse/BED-4597

Adds configurable log rotation and retention for file-based logging, preventing AzureHound log files from growing indefinitely.

  • Rotates logs based on a configurable maximum size.
  • Prunes archives by age and backup count.
  • Compresses rotated logs with gzip by default.
  • Adds the new settings to CLI flags and the interactive configuration flow.
  • Validates logging settings and rejects directory-valued log paths.
  • Documents the behavior and adds test coverage.

Defaults retain up to 20 archives or 14 days of history and rotate the active log at 100 MiB.

  • Bug Fixes

    • Invalid logging configurations now prevent startup with clear errors.
    • File logging failures and directory-based log paths are reported instead of silently ignored.
  • Tests

    • Added coverage for configuration validation, rotating file output, compression, and invalid log paths.

Walkthrough

The PR adds persistent log rotation settings, interactive prompts, validation before logger initialization, and lumberjack-based file logging. Tests cover configuration validation, writer settings, invalid paths, and log output.

Changes

Logging configuration and rotation

Layer / File(s) Summary
Configuration and validation
config/config.go, config/utils.go, config/utils_test.go
Configuration includes rotation size, age, backup count, and compression. Validation checks log paths and retention limits.
Interactive configuration prompts
cmd/configure.go, cmd/configure_test.go
Prompts support defaults and collect validated rotation settings.
Rotating logger integration
logger/..., cmd/utils.go, cmd/svc_windows.go, logger/utils_test.go
Logger setup uses cached lumberjack writers, propagates errors, and validates configuration during startup. Tests cover writer creation, invalid paths, permissions, and log output.
Rotation support documentation and dependency
go.mod, README.md
The dependency enables rotating file logging. Documentation describes rotation, compression, retention, disabled limits, and the single-process constraint.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to 5c4c2

A configured but non-writable log file can let the application start successfully and fail only when the first log entry is written, potentially leaving users without expected logs; the PR is otherwise mergeable with explicit owner awareness or follow-up for this bounded reliability risk.

Poem

A rabbit tunes the logs at night
Gzip keeps rotated files light
Prompts collect each setting true
Invalid paths stop the queue
Rotating files hop into view

In `@logger/utils.go`:
- Around line 41-48: The getFileLogLevelWriter flow must preflight the
configured logfile before assigning and caching the lumberjack.Logger, so an
existing inaccessible regular file causes GetLogger to fail rather than the
first Write. Validate that the destination is writable using the existing
logging configuration helpers, preserve directory rejection, and add a
regression test covering an inaccessible regular file.
