What's New (since v0.07)

• Top 10 Consumers, merged per app: the panel now lists the top 10 power-draining apps plus an "Other" tail (was top 5). Helper/renderer sub-processes are folded into their parent app — "Google Chrome Helper (Renderer)" and friends now count as one "Google Chrome", including data already recorded by v0.07.
• Interactive chart: hover for an exact value tooltip; click any bar to pin the Top Consumers list to that hour/day (click again to release). The title shows the selected bucket, and switching ranges clears the selection.
• Data management menu (right-click → Data): reset cumulative counters (chart history kept), back up / restore the three data files, and reveal the data folder in Finder.
• Raw-sample retention: raw samples.jsonl now rolls over, keeping 7 days (aggregated hour/day buckets keep full history — charts unaffected). The file shrinks from tens of MB to ~12 MB.
• status.json for integrations: every minute the app atomically writes a snapshot (live power, today/total kWh, estimated cost, top 10 consumers, uptime; ISO 8601 timestamps) into the data folder — ready for scripts, Grafana and home-automation polling. No network service involved.
• Sustained process alert (off by default): when system power exceeds your threshold and a single process holds ≥50% of the energy score for 5 minutes, you get one notification (30-min cooldown per process). Enable via right-click → "Process Power Alert".
• Status bar color cue: the bolt icon turns red while power is at/above your alert threshold.

新功能（相比 v0.07）

• 耗电应用 TOP 10（按应用合并）：列表从 TOP 5 扩到 TOP 10 + 「其他」行。Helper/Renderer 子进程归并到主应用——「Google Chrome Helper (Renderer)」等现在计为一个 Google Chrome，v0.07 已记录的历史数据同样生效。
• 图表可交互：悬停显示精确数值气泡；点击任意柱把 TOP 列表锁定到该小时/当天（再次点击取消），标题显示选中时段，切换区间自动清除。
• 数据管理菜单（右键 →「数据」）：重新累计（保留图表历史）、备份/恢复三个数据文件、在 Finder 中查看数据目录。
• 原始样本滚动清理：samples.jsonl 只保留 7 天（小时/天聚合桶保留完整历史，图表不受影响），文件从数十 MB 降到约 12 MB。
• status.json 对接外部：每分钟原子写出一个快照（实时功率、今日/累计电量、估算费用、TOP 10 应用、运行时长，ISO 8601 时间戳）到数据目录，可直接被脚本、Grafana、自动化轮询，不引入任何网络服务。
• 进程持续高耗电告警（默认关）：整机功率超过阈值且单个进程持续 5 分钟占据能耗分半数以上时通知一次（同进程 30 分钟冷却），右键 →「进程耗电告警」开启。
• 状态栏颜色提示：功率达到告警阈值时闪电图标变红，回落后还原。

What's New (since v0.06)

• Top Consumers panel: a new "Top Consumers" section under the power trend chart — the top 5 power-draining apps plus an "Other" tail for the selected range (24H/7D/30D), each with a share bar, percentage and attributed Wh. Follows the chart's range selector instantly.
• Per-process energy attribution: powered by powermetrics --show-process-energy (Energy Impact). Attribution uses each app's share of the system energy score × measured Wh of the range — a weighted estimate, not metered accuracy; ranking and percentages are reliable. Measurement daemons and OS aggregate pseudo-tasks (powermetrics/ALL_TASKS/DEAD_TASKS) are excluded.
• Hourly accrual with tiny footprint: buckets mirror the existing hour/day aggregation (168h / 365d retention) and persist to an append-only process_energy.jsonl (~0.7 KB/hour); the in-progress bucket survives restarts via flush-and-continue.

新功能（相比 v0.06）

• 耗电应用 TOP 列表：功率趋势图下方新增「耗电应用 TOP」区块——显示当前区间（24H/7D/30D）耗电前 5 的应用 + 「其他」长尾行，每行带占比条、百分比与归因 Wh，随图表区间切换即时重算。
• 按进程能耗归因：数据来自 powermetrics --show-process-energy（Energy Impact）。归因方式为各应用能耗分占比 × 区间实测总 Wh——加权估算值而非电表精度，排名与百分比可靠。已排除测量进程与系统聚合伪任务（powermetrics/ALL_TASKS/DEAD_TASKS）。
• 按小时累积、占用极小：桶结构与既有小时/天聚合一致（保留 168 小时 / 365 天），落盘为 append-only 的 process_energy.jsonl（约 0.7 KB/小时）；进行中的桶经退出补写，重启自动续算。

What's New (since v0.05)

• Net speed component: monitor upload/download rates right in the status bar (↑/↓), sampled via getifaddrs — zero processes, zero permissions; physical interfaces only (no VPN double-counting).
• Composable status bar: replaced the 6 fixed modes with independent toggles — Power / cumulative Cost / cumulative Energy / Net speed. Check any combination; none checked = icon only. Existing preferences migrate automatically.
• Energy now shows cumulative kWh, consistent with cumulative cost.

Critical Fix

• Fixed a CPU spin bug in v0.03: an unconsumed stderr readability handler busy-looped at ~98% CPU once powermetrics wrote anything to stderr. stderr is now redirected to /dev/null. Measured: 98.3% → 0.0% CPU.

If v0.03 made your Mac run hot / showed abnormally high power readings, this was why — please update.

Install

1. Download PowerCumul-0.04.dmg
2. Drag PowerCumul to Applications (replace old version)
3. First launch: right-click app → Open → Open Anyway (once)

严重修复

• 修复 v0.03 空转 bug：stderr 的 readabilityHandler 未消费数据导致 busy-loop，powermetrics 一旦写 stderr 就烧满一个核（~98% CPU）。现改为 stderr 接 /dev/null。实测 98.3% → 0.0%。

如果 v0.03 让你机器发热/功率读数异常偏高，就是这个原因——请升级。

PowerCumul v0.03

What's New (since v0.02)

• Continuous streaming sampling: powermetrics now runs as a long-lived process, parsing every sample block — 100% time coverage, zero extrapolation error. The old approach (spawn every 5s, measure 1s, extrapolate) is gone, along with its ~17k process spawns/day overhead.
• DRAM counted: idle power no longer drops to 0 — DRAM draw is added to the Combined total.
• Sleep gap fix: gaps over 90s (sleep/outage) are no longer charged at full power.
• Throttled disk writes: state/raw files flush every 5s instead of per-sample.
• Cost now cumulative: daily cost at idle is literally fractions of a cent (Mac mini idles at 2–6W), so the panel and status bar now show cumulative cost with 3 decimals — a number that actually moves.

新功能（相比 v0.02）

• 连续流式采样：powermetrics 改为常驻进程逐块解析，100% 时间覆盖、零外推误差。旧方案（每 5s 启动一次、测 1 秒外推 5 秒）及其每天 1.7 万次进程创建开销一并移除。
• 计入 DRAM：空闲时功率不再整段记 0，内存耗电补进总量。
• 修复睡眠缺口：超过 90 秒的缺口（睡眠/中断）不再按满功率记账。
• 落盘节流：状态与原始流每 5 秒写一次，不再逐样本写盘。
• 费用改显示累计：Mac mini 空闲日电费只有几分钱（2 位小数恒为 0.00），面板与状态栏改为累计电费 + 3 位小数，数字真正看得见增长。
