Configuration

Environment Variables

Edit .env to customize:

# Paths
OPENCLAW_AGENTS_DIR=/home/youruser/.openclaw/agents
CLAWMETER_DB=/home/youruser/.openclaw/workspace/clawmeter/data/clawmeter.db

# Server
PORT=3377

# Budgets (USD)
BUDGET_DAILY_LIMIT=5.00
BUDGET_MONTHLY_LIMIT=100.00

# Telegram alerts (optional)
TELEGRAM_BOT_TOKEN=your_bot_token

Budget Alerts

ClawMeter automatically checks spending against configured thresholds and sends alerts via:

• Telegram — Instant notifications to your phone
• Email — Delivered via SMTP

Alert triggers:

• Daily spend exceeds BUDGET_DAILY_LIMIT
• Monthly spend exceeds BUDGET_MONTHLY_LIMIT

Alert throttling: One alert per type per day (prevents spam).

Agent Integration Examples

Example 1: Daily Spend Check

User: "How much have I spent today?"

Agent Response:

Let me check your spending...

📊 Today's Spend: $2.15
Budget: $5.00 (43% used)

You have $2.85 remaining today.

Implementation:

const res = await fetch('http://localhost:3377/api/summary');
const data = await res.json();
const pct = (data.today / data.budgetDaily * 100).toFixed(0);
return `📊 Today's Spend: $${data.today.toFixed(2)}\nBudget: $${data.budgetDaily.toFixed(2)} (${pct}% used)\n\nYou have $${(data.budgetDaily - data.today).toFixed(2)} remaining today.`;

Example 2: Model Comparison

User: "Which model should I use to save money?"

Agent Response:

Based on your usage history:

💰 Cost per 1K messages:
• Claude Haiku 3-5: $0.12
• GPT-4o-mini: $0.18
• Claude Sonnet 4-5: $0.45
• Claude Opus 4: $1.23

Recommendation: Use Haiku for simple tasks, Sonnet for complex work.

Example 3: Budget Warning

Agent (proactive):

⚠️ Budget Alert

You've spent $5.52 today, exceeding your $5.00 daily limit.

Top sessions today:
1. Code review task — $2.10
2. Research project — $1.85
3. Email drafting — $0.98

Consider switching to a cheaper model or pausing non-urgent tasks.

3. Model Selection Optimization

Scenario: You're unsure which model to use for different tasks.

Setup:

• Run experiments with different models
• Compare costs in ClawMeter dashboard
• Analyze cost-per-message and cost-per-token

Result: Data-driven model selection, optimize for cost/quality balance.

4. Production Monitoring

Scenario: OpenClaw running in production, need cost visibility.

Setup:

• ClawMeter auto-ingests logs in real-time
• Set aggressive budget alerts
• Monitor dashboard for anomalies

Result: Catch cost spikes immediately, prevent runaway spending.

Troubleshooting

Dashboard shows $0.00

Cause: Session logs not found or not yet ingested.

Fix:

1. Verify OPENCLAW_AGENTS_DIR points to correct path
2. Run npm run ingest manually
3. Check that .jsonl files exist in agents/*/sessions/

Auto-watch not working

Cause: File watcher not detecting changes.

Fix:

1. Ensure server is running (npm start)
2. Check terminal for 📥 X new events messages
3. Verify file permissions on session directories

Budget alerts not sending

Cause: Missing or incorrect credentials.

Fix:

1. Double-check TELEGRAM_BOT_TOKEN and TELEGRAM_CHAT_ID in .env
2. For email, verify SMTP settings
3. Check server logs for error messages

Database errors

Cause: Corrupted or locked database file.

Fix:

1. Stop the server
2. Backup data/clawmeter.db
3. Delete database and re-run npm run ingest

Advanced Configuration

Custom Model Pricing

If you use custom models or pricing changes:

1. Edit src/pricing.mjs
2. Add entry to MODEL_PRICING object:

   'your-custom-model': {
     input: 2.50,    // per million tokens
     output: 10.00,  // per million tokens
     cacheRead: 0.25,   // optional
     cacheWrite: 3.75   // optional
   }
   

3. Restart server

Scheduled Reports

Use cron to schedule daily/weekly reports:

# Daily summary at 9 AM
0 9 * * * curl -s http://localhost:3377/api/summary | mail -s "Daily Cost Report" you@example.com

Data Export

Export raw data for external analysis:

# Export all sessions to CSV
sqlite3 data/clawmeter.db "SELECT * FROM sessions" -csv > sessions.csv

Running as a Service

Create systemd service for persistent operation:

# /etc/systemd/system/clawmeter.service
[Unit]
Description=ClawMeter Cost Tracking Dashboard
After=network.target

[Service]
Type=simple
User=youruser
WorkingDirectory=/home/youruser/.openclaw/workspace/clawmeter
ExecStart=/usr/bin/npm start
Restart=always

[Install]
WantedBy=multi-user.target

Enable and start:

sudo systemctl enable clawmeter
sudo systemctl start clawmeter

Security Considerations

Local Access Only

By default, ClawMeter binds to localhost:3377 and is not exposed to the internet.

To access remotely, use SSH tunneling:

ssh -L 3377:localhost:3377 your-server

Sensitive Data

Session logs may contain conversation data. ClawMeter:

• Stores only usage metadata (tokens, costs, timestamps)
• Does not store message content or prompts
• Database is local SQLite (no cloud sync)

API Authentication

ClawMeter currently has no authentication. For production:

1. Run behind a reverse proxy (nginx/caddy) with auth
2. Use firewall rules to restrict access
3. Deploy on a private network

Performance

Resource Usage

• CPU: Minimal (event-driven ingestion)
• RAM: ~50-100 MB
• Disk: Database grows ~1 KB per message (SQLite is very efficient)
• Network: None (all local)

Scalability

ClawMeter handles:

• 100K+ messages easily
• Years of historical data without performance degradation
• Multiple agents (separated by directory structure)

For massive deployments (millions of messages), consider:

• Periodic database archiving
• PostgreSQL backend (requires code changes)

Roadmap

Planned features:

• Multi-user authentication
• PostgreSQL support for large deployments
• Export to CSV/JSON
• Cost forecasting (predict monthly spend)
• Slack/Discord webhook support
• Token usage heatmaps
• Model performance tracking (latency, quality)
• Budget recommendations based on usage patterns

• Issues: GitHub Issues
• Community: OpenClaw Discord
