- Extract shared send_event/clear_event into detectors/base.py, removing ~150 lines of duplication across all 6 detectors - Fix default aggregator URL from port 5000 to 5100 in all detectors - Standardize cpu.py and memory.py to use active_alerts set pattern - Fix immediate emote rotation on startup (last_emote_change = time.time()) - Extract magic numbers to named constants in aggregator - Protect write_status() with try/except OSError - Fix notify event ID collision with monotonic counter - Replace blocking stream_output() with background daemon threads in kao.py Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Memory Usage Detector

Monitors RAM usage and reports to the aggregator when thresholds are exceeded.
|
|
|
|
Environment variables:
|
|
AGGREGATOR_URL - URL of the aggregator (default: http://localhost:5100)
|
|
CHECK_INTERVAL - Seconds between checks (default: 30)
|
|
THRESHOLD_CRITICAL - Percent usage for critical alert (default: 95)
|
|
THRESHOLD_WARNING - Percent usage for warning alert (default: 85)
