新增实时监控模式,agent 1s 并行采集 + 前端滑动窗口
agent - 移除 collector.interval 配置项;按指标类型内置节奏:cpu/memory/network/ disk_io/gpu/network_connection 1s,temperature 5s,disk 30s,host 60s - doCollectAndSend 改为并行执行本 tick 到期的采集器,避免串行累计耗时 超过 1s 节奏;每个 goroutine 加 recover 兜底,单点 panic 不拖垮整 tick server - LatestMetrics 加 sync.RWMutex + Update/Snapshot 方法,HandleMetricData 所有写入走 Update;GetLatestMetrics 返回 Snapshot,handler 在副本上 sanitize,修复 marshal 时与 ws 写入的 data race(go test -race 验证) - HandleMetricData defer Set 缓存项,每次上报刷新 TTL;host case 也走 Update,不再 1 小时后失效 - LatestMetrics.Timestamp 用服务端 time.Now(),agent 时钟倒拨不会冻结 前端实时图;Timestamp/DiskIOSummary 字段补到 LatestMetrics - AutoStep 新增 r ≤ 5m → 1s 档;timeRangeMilliseconds 加 2m frontend - 详情页加"实时"档位(默认),1s 拉 latestMetrics + 1m 历史播种 + 滑动 2 分钟窗口;快图表(CPU/Memory/Network/DiskIO/NetworkConnection)走 useLiveBuffer 追加,慢图表(GPU/Temperature/Monitor)保留 refetch - useLiveBuffer:seed 不再覆盖已追加的 livePoint;resetKey 处理切网卡 / 切 agent 时的语义复位 - formatChartTime live 档位精确到秒;修复 1d/24h 仅显示 HH:mm 跨夜歧义 - 慢图表用 React.memo,阻断 1Hz 节奏的级联重渲染 - GpuChart 修复 utilization/temperature 时间戳错位时温度点丢失 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
