Zeam Dashboards

This repository contains Grafana dashboards and monitoring infrastructure for the Zeam blockchain node.

Overview

This repository provides:

• Grafana Dashboards: Pre-configured dashboards for monitoring Zeam node performance
• Docker Compose Setup: Complete monitoring stack with Prometheus and Grafana
• Prometheus Configuration: Templates and examples for Prometheus setup

Quick Start

Prerequisites

• Docker and Docker Compose installed
• A running Zeam node with metrics enabled

1. Prometheus Configuration

A basic Prometheus configuration is included in prometheus/prometheus.yml that will work out of the box.

Option A: Use the included configuration (Recommended for quick start) The repository includes a basic prometheus/prometheus.yml that will start monitoring:

• Prometheus itself (localhost:9090)
• A Zeam node running on the host (host.docker.internal:9667)
• Node exporter if available (host.docker.internal:9100)

Option B: Generate custom configuration (Advanced users) If you have access to the main Zeam repository, you can generate a custom configuration:

# From your Zeam repository
./zig-out/bin/zeam generate_prometheus_config --output /path/to/zeam-dashboards/prometheus/prometheus.yml

2. Start the Monitoring Stack

# Clone this repository
git clone https://github.com/blockblaz/zeam-dashboards.git
cd zeam-dashboards

# Start Prometheus and Grafana (uses included configuration)
docker-compose up -d

3. Access Dashboards

• Grafana: http://localhost:3001 (admin/admin)
• Prometheus: http://localhost:9090

4. Configure Grafana Data Source

1. Open Grafana at http://localhost:3001
2. Go to Configuration → Data Sources
3. Add Prometheus data source:
   • URL: http://prometheus:9090
   • Access: Server (default)

Dashboard Features

Main Dashboard

The main dashboard (grafana/dashboards/main.json) includes:

• P95 Block Processing Time: 95th percentile of block processing duration
• Block Processing Rate: Number of blocks processed per second
• System Health: Overall node health indicators

Configuration

Environment Variables

You can customize the setup using environment variables:

# Custom ports
export PROMETHEUS_PORT=9090
export GRAFANA_PORT=3001

# Start with custom configuration
docker-compose up -d

Prometheus Configuration

The repository includes a basic prometheus/prometheus.yml configuration that works out of the box. You can customize it for your specific setup:

Basic Configuration Includes:

• Prometheus self-monitoring (localhost:9090)
• Zeam node monitoring (host.docker.internal:9667)
• Node exporter monitoring (host.docker.internal:9100)

Customizing the Configuration:

• Edit prometheus/prometheus.yml to add your specific targets
• Update scrape intervals as needed
• Add alert rules and retention policies

For Advanced Users: If you have access to the main Zeam repository, you can generate a custom configuration using the Zeam CLI:

./zig-out/bin/zeam generate_prometheus_config --output prometheus/prometheus.yml

Development

Adding New Dashboards

1. Create dashboard JSON in grafana/dashboards/
2. Update grafana/provisioning/dashboards/dashboards.yml if needed
3. Restart Grafana: docker-compose restart grafana

Customizing Dashboards

Dashboards are stored in grafana/dashboards/ and can be:

• Modified directly in JSON format
• Exported from Grafana UI
• Version controlled with Git

Troubleshooting

Common Issues

1. Prometheus can't scrape Zeam node:

   • Verify Zeam node is running with --metricsPort flag
   • Check firewall settings
   • Ensure Prometheus config targets match Zeam metrics port
   • If your Zeam node is not on the default port 9667, edit prometheus/prometheus.yml and update the target

2. Grafana can't connect to Prometheus:

   • Verify Prometheus is running: docker-compose ps
   • Check data source URL in Grafana
   • Ensure both services are on the same Docker network

3. No metrics appearing:

   • Verify Zeam node is generating metrics
   • Check Prometheus targets page
   • Review Prometheus logs: docker-compose logs prometheus
