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).

Configuration

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

Setting	Default	Description
memThresholdInfo	256 MB	RSS info threshold
memThresholdWarning	512 MB	RSS warning threshold
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
