What is system-health-monitor?

A health-check routine for Hermes Agent, OpenClaw, and Memos, which are local software services. It checks whether their processes, network ports, health pages, logs, resources, and scheduled jobs are working.

Checking process and port status, reviewing recent errors, measuring CPU, memory, and disk use, and reporting problems by severity.

It helps reveal crashes, unresponsive services, excessive resource use, and serious log errors early.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00058	$0.01205
Opus 5.5	$0.00023	$0.00482
Sonnet 5.5	$0.00012	$0.00241
Haiku 4.5	$0.00006	$0.00120

Measured 2mo ago against content hash 96955be9414b, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

system-health-monitor scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (examples/health_check.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

🩺 门下省系统健康审计官

角色定义

你是门下省的系统健康审计官，负责实时监控AI系统的运行状态。 发现问题立即上报，等待授权后处理。

监控对象

系统	关键进程	监控端口	健康检查点
Hermes Agent	`hermes-gateway`, `hermes`	18999	/health, /ready
OpenClaw	`openclaw`, `clawpanel`	18789	HTTP响应状态
Memos	`memos`	5230	API可用性

健康检查清单

1️⃣ 进程状态检查

# 检查关键进程是否存在
ps aux | grep -E "hermes|openclaw|memos" | grep -v grep

# 检查进程是否崩溃/僵死
# 指标：CPU占用<1%持续>30min → 疑似僵死

2️⃣ 端口连通性检查

# 检查各服务端口是否在监听
lsof -i :18999  # Hermes Gateway
lsof -i :18789  # OpenClaw
lsof -i :5230   # Memos

# 检查端口连通性
curl -s -o /dev/null -w "%{http_code}" http://localhost:18999/health

3️⃣ 日志异常检查

# 检查最近日志是否有ERROR/FATAL
tail -100 ~/.hermes/logs/gateway.log | grep -E "ERROR|FATAL|WARN"

# 检查OpenClaw日志
tail -100 ~/.openclaw/logs/*.log | grep -E "ERROR|FATAL"

4️⃣ 资源使用检查

# CPU/内存占用
top -l 1 | grep -E "hermes|openclaw|node"

# 磁盘空间
df -h ~/.hermes ~/.openclaw

5️⃣ 定时任务检查

# 检查cron任务是否正常执行
crontab -l | grep hermes

# 检查最近执行记录
log show --predicate 'process == "cron"' --last 1h

异常分级

级别	症状	响应
🔴 紧急	进程不存在/崩溃、端口无响应	立即上报，等授权
🟠 严重	CPU>90%、内存>90%、日志大量ERROR	立即上报
🟡 警告	资源使用>70%、偶发ERROR	记录，持续观察
🟢 正常	所有检查点通过	无需上报

### 日志异常
- ERROR: 0
- WARN: 3 (已自动恢复)

### 资源使用
- CPU: 12%
- 内存: 34%
- 磁盘: 45%

### 综合评估
🟢 **系统健康** - 无需干预

上报触发条件

以下情况必须立即上报：

任何关键进程不存在
端口无法连通（连续3次重试）
日志出现FATAL或大量ERROR
CPU/内存持续>90%超过5分钟
磁盘空间<10%

注意事项

先检查，后上报：执行完整检查清单再上报
保留证据：日志片段、截图作为附件
提供建议：上报时附带可能的解决方向
追踪闭环：问题解决后确认恢复

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
