Monitoring Stack

1. Prometheus Setup

global:
  scrape_interval: 15s

scrape_configs:
  - job_name: 'validator'
    static_configs:
      - targets: ['localhost:26660']

  - job_name: 'node'
    static_configs:
      - targets: ['localhost:9100']

2. Node Exporter

# Installation
apt install -y prometheus-node-exporter

# Service configuration
systemctl enable node_exporter
systemctl start node_exporter

3. Grafana Dashboards

Dashboard Components:
- Validator status
- Block production
- Resource usage
- Network health
- Alert status

Alert Configuration

Critical Alerts

groups:
  - name: validator_alerts
    rules:
      - alert: MissedBlocks
        expr: increase(cosmos_validator_missed_blocks[5m]) > 0
        
      - alert: LowPeerCount
        expr: cosmos_p2p_peers < 10
        
      - alert: HighCPUUsage
        expr: cpu_usage_percent > 80
        
      - alert: DiskSpaceLow
        expr: disk_free_percent < 20

Warning Alerts

groups:
  - name: warning_alerts
    rules:
      - alert: HighMemoryUsage
        expr: memory_usage_percent > 80
        
      - alert: PeerCountDecreasing
        expr: rate(cosmos_p2p_peers[15m]) < 0

Response Procedures

Alert Response Matrix

Priority 1 (Immediate):
- Missed blocks
- Node offline
- Security breach

Priority 2 (30 mins):
- High resource usage
- Network issues
- Peer count low

Priority 3 (4 hours):
- Performance warnings
- Minor anomalies

Incident Management

1. Detection

   • Alert received
   • Issue confirmed
   • Severity assessed

2. Response

   • Team notified
   • Actions taken
   • Status updated

3. Resolution

   • Issue fixed
   • Root cause analyzed
   • Documentation updated

Log Management

Log Collection

# Validator logs
journalctl -u cosmosd -f

# System logs
tail -f /var/log/syslog

# Security logs
tail -f /var/log/auth.log

Log Analysis

Important Patterns:
- Error messages
- Warning signs
- Performance issues
- Security events

Performance Monitoring

Key Metrics

1. Block Production

   • Block time
   • Block size
   • Transaction count

2. Network Health

   • Peer count
   • Bandwidth usage
   • Latency

3. Resource Usage

   • CPU load
   • Memory profile
   • Disk operations

Backup Monitoring

Backup Verification

# Check backup status
0 */6 * * * /scripts/verify_backup.sh

# Verify snapshot integrity
0 0 * * * /scripts/check_snapshot.sh

Recovery Testing

• Weekly backup tests
• Monthly recovery drills
• Quarterly DR exercises

Security Monitoring

Access Monitoring

# Monitor SSH access
tail -f /var/log/auth.log

# Track sudo usage
journalctl _COMM=sudo

Network Monitoring

# Monitor connections
netstat -tunlp

# Track bandwidth
iftop -i eth0
