Monitoring stack configuration

better-openclaw includes optional monitoring with Prometheus (metrics), Grafana (dashboards), and Loki (logs).

Enabling monitoring

Add monitoring services when generating your stack:

npx create-better-openclaw
# Select "Include monitoring stack" when prompted

Architecture

Prometheus: Scrapes metrics from services every 15 seconds
Grafana: Visualizes metrics and logs with dashboards
Loki: Aggregates logs from Docker containers

Prometheus configuration

Generated files

When monitoring is enabled, better-openclaw generates:

config/prometheus/prometheus.yml - Scrape configuration
docker-compose.yml - Prometheus service definition

Scrape configuration

better-openclaw automatically detects which services expose Prometheus metrics and adds them to prometheus.yml:

config/prometheus/prometheus.yml

global:
  scrape_interval: 15s
  evaluation_interval: 15s
  scrape_timeout: 10s

scrape_configs:
  # Prometheus self-monitoring
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]
        labels:
          service: "prometheus"
          component: "monitoring"

  # 🔴 Redis
  - job_name: "redis"
    metrics_path: "/metrics"
    static_configs:
      - targets: ["redis:9121"]
        labels:
          service: "redis"
          component: "database"

  # 🐘 PostgreSQL

          service: "postgresql"
          component: "database"

  # 📊 Grafana
  - job_name: "grafana"
    metrics_path: "/metrics"
    static_configs:
      - targets: ["grafana:3000"]
        labels:
          service: "grafana"
          component: "monitoring"

  # 🐾 OpenClaw Gateway
  - job_name: "openclaw-gateway"
    metrics_path: "/metrics"
    static_configs:
      - targets: ["openclaw:18789"]
        labels:

Grafana configuration

Generated files

config/grafana/provisioning/datasources/prometheus.yml - Auto-configure Prometheus datasource
config/grafana/provisioning/dashboards/default.yml - Dashboard provider
config/grafana/grafana.ini - Grafana server config
config/grafana/dashboards/openclaw-overview.json - Default dashboard

Datasource provisioning

config/grafana/provisioning/datasources/prometheus.yml

apiVersion: 1

datasources:
  - name: Prometheus
    type: prometheus
    access: proxy
    url: http://prometheus:9090
    isDefault: true
    editable: true
    jsonData:
      httpMethod: POST

Grafana automatically connects to Prometheus on startup—no manual configuration required.

Dashboard provisioning

better-openclaw includes a default OpenClaw Stack Overview dashboard:

Service Health: Count of healthy services
Memory Usage: Container memory utilization
Request Rate: HTTP requests per second

Docker Compose

docker-compose.yml

services:
  grafana:
    image: grafana/grafana:10.2.2
    volumes:
      - grafana-data:/var/lib/grafana
      - ./config/grafana/provisioning:/etc/grafana/provisioning:ro
      - ./config/grafana/grafana.ini:/etc/grafana/grafana.ini:ro

Loki configuration

Loki aggregates logs from all Docker containers.

Docker Compose

docker-compose.yml

services:
  loki:
    image: grafana/loki:2.9.3
    ports:
      - "${LOKI_EXTERNAL_PORT:-3100}:3100"
    command: -config.file=/etc/loki/local-config.yaml
    networks:
      - openclaw-network
    restart: unless-stopped

  promtail:
    image: grafana/promtail:2.9.3
    volumes:
      - /var/log:/var/log:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./config/promtail/config.yml:/etc/promtail/config.yml:ro
    command: -config.file=/etc/promtail/config.yml
    networks:
      - openclaw-network
    depends_on:
      - loki
    restart: unless-stopped

Promtail ships Docker container logs to Loki.

Add Loki datasource to Grafana

Open Grafana → Configuration → Data Sources
Click “Add data source”
Select “Loki”
URL: http://loki:3100
Click “Save & Test”

Query logs

In Grafana, go to Explore:

# All logs from openclaw-gateway
{container_name="openclaw-gateway"}

# Errors from all services
{job="docker"} |= "error" or "ERROR"

# PostgreSQL slow queries
{container_name="postgresql"} |~ "duration: [0-9]{4,} ms"

Custom dashboards

Creating dashboards

Open Grafana
Click ”+” → “Dashboard”
Add panels with PromQL queries:

# Service uptime
up{job="openclaw-gateway"}

# Memory usage
container_memory_usage_bytes{name="openclaw-gateway"}

# Request rate
rate(http_requests_total[5m])

# Error rate
rate(http_requests_total{status=~"5.."}[5m])

Importing dashboards

Grafana has thousands of community dashboards:

Browse at grafana.com/grafana/dashboards
Find a dashboard (e.g., “Docker and system monitoring”)
Copy the dashboard ID
In Grafana: Dashboards → Import → Paste ID

Recommended dashboards:

1860: Node Exporter Full (system metrics)
893: Docker monitoring
6417: PostgreSQL Database
7362: Redis Dashboard
11074: Traefik 2.0

Alerting

Prometheus alerting rules

Create config/prometheus/alerts.yml:

groups:
  - name: openclaw
    interval: 30s
    rules:
      - alert: ServiceDown
        expr: up == 0
        for: 1m
        labels:
          severity: critical
        annotations:
          summary: "Service {{ $labels.job }} is down"
          description: "{{ $labels.job }} has been down for more than 1 minute"

      - alert: HighMemoryUsage
        expr: (container_memory_usage_bytes / container_spec_memory_limit_bytes) > 0.9
        for: 5m
        labels:
          severity: warning
        annotations:
          summary: "High memory usage on {{ $labels.name }}"
          description: "{{ $labels.name }} memory usage is above 90%"

      - alert: HighErrorRate
        expr: rate(http_requests_total{status=~"5.."}[5m]) > 0.05
        for: 5m
        labels:
          severity: warning
        annotations:
          summary: "High error rate on {{ $labels.service }}"
          description: "{{ $labels.service }} has >5% error rate"

Mount in docker-compose.yml:

services:
  prometheus:
    volumes:
      - ./config/prometheus/alerts.yml:/etc/prometheus/alerts.yml:ro
    command:
      - '--config.file=/etc/prometheus/prometheus.yml'
      - '--storage.tsdb.path=/prometheus'
      - '--web.enable-lifecycle'

Update prometheus.yml:

rule_files:
  - 'alerts.yml'

alerting:
  alertmanagers:
    - static_configs:
        - targets: ['alertmanager:9093']

Grafana alerts

Open a dashboard panel
Click “Alert” tab
Create alert rule:
- Condition: WHEN avg() OF query(A, 5m, now) IS ABOVE 90
- Frequency: Evaluate every 1m
- Notification: Send to Slack/Email/PagerDuty

Uptime monitoring

Add Uptime Kuma for HTTP/ping monitoring:

npx create-better-openclaw --services uptime-kuma --yes

Uptime Kuma provides:

HTTP(s) monitoring
TCP port monitoring
Ping/DNS monitoring
Status pages
Multi-channel notifications (Slack, Discord, Email, etc.)

Access at http://localhost:3001

Performance tuning

Prometheus retention

Adjust data retention in docker-compose.yml:

services:
  prometheus:
    command:
      - '--storage.tsdb.retention.time=30d'  # Keep 30 days
      - '--storage.tsdb.retention.size=10GB'  # Or 10GB max

Scrape interval

Reduce scrape frequency for less critical services:

prometheus.yml

scrape_configs:
  - job_name: "high-priority"
    scrape_interval: 10s
    static_configs:
      - targets: ["openclaw:18789"]

  - job_name: "low-priority"
    scrape_interval: 60s
    static_configs:
      - targets: ["uptime-kuma:3001"]

Grafana performance

config/grafana/grafana.ini

[database]
# Use PostgreSQL instead of SQLite for better performance
type = postgres
host = postgresql:5432
name = grafana
user = grafana
password = ${GF_DATABASE_PASSWORD}

[dashboards]
# Cache dashboard queries
min_refresh_interval = 5s

Troubleshooting

Prometheus not scraping targets

Check Prometheus logs:
```
docker compose logs prometheus
```
Verify service is exposing metrics:
```
curl http://localhost:9090/metrics
```

Check network connectivity:

docker compose exec prometheus ping redis

Grafana can’t connect to Prometheus

HTTP Error Bad Gateway

Verify datasource URL in Grafana settings:

✅ http://prometheus:9090 (Docker network)
❌ http://localhost:9090 (won’t work inside container)

High disk usage

Prometheus data grows over time. Clean up old data:

# Check volume size
docker system df -v

# Remove old Prometheus data
docker compose down prometheus
docker volume rm prometheus-data
docker compose up -d prometheus

Or configure retention (see Performance tuning above).
