dsh-flash-mem-mon
Memory monitor provider for dsh-flash — registers a host-memory-alert provider (RSS absolute thresholds, RSS growth rate, Major GC frequency) via ctx.get('dockFlashAlerts') and exposes /memory-trend for trend sparklines.
Installation
dsh plugin --profile <profile> add dsh-flash-mem-mon
Requires dsh-flash >=1.0.0 (provides dockFlashAlerts and quickControl services).

All settings are live-editable (volatile) and take effect immediately:

memThresholdError | 1024 MB | RSS error threshold |
memThresholdCritical | 1536 MB | RSS critical threshold |
memPollBase | 30000 ms | Base polling interval |
memPollMin | 2000 ms | Minimum polling interval |
gcThresholdInfo | 2 /min | Major GC info threshold |
gcThresholdWarning | 5 /min | Major GC warning threshold |
gcThresholdError | 10 /min | Major GC error threshold |
memGrowthAlertPerMin | 1 MB/min | RSS growth-rate (linear-regression slope) alert threshold, applied with trend = up |
Architecture
This is a companion plugin following the same two-half pattern as dsh-flash-net-mon:
- Host half (
src/index.ts → tsc → dist/index.js): Memory trend ring buffer, GC observer, /memory-trend HTTP route
- Client half (
lib/client.js): Alert provider, enable toggle, config modal with sparkline, i18n via DSH's locale service
