• Target monitoring

Grafana

URL: http://172.16.3.30:3000 Login: admin / admin (MUST CHANGE ON FIRST LOGIN) Data Source: Prometheus (pre-configured)

---

Next Steps (Required)

1. Change Grafana Password

# Access Grafana
open http://172.16.3.30:3000

# Login with admin/admin
# You will be prompted to change password

2. Import Grafana Dashboard

# Option A: Via Web UI
1. Go to http://172.16.3.30:3000
2. Login
3. Navigate to: Dashboards > Import
4. Click "Upload JSON file"
5. Select: ~/guru-connect/infrastructure/grafana-dashboard.json
6. Click "Import"

# Option B: Via Command Line (if needed)
ssh guru@172.16.3.30
curl -X POST http://admin:NEW_PASSWORD@localhost:3000/api/dashboards/db \
  -H "Content-Type: application/json" \
  -d @~/guru-connect/infrastructure/grafana-dashboard.json

3. Verify Prometheus Targets

# Check targets are UP
open http://172.16.3.30:9090/targets

# Expected:
- guruconnect (172.16.3.30:3002) - UP
- node_exporter (172.16.3.30:9100) - UP

4. Test Manual Backup

ssh guru@172.16.3.30
cd ~/guru-connect/server
./backup-postgres.sh

# Verify backup created
ls -lh /home/guru/backups/guruconnect/

---

Next Steps (Optional)

5. Configure External Access (via NPM)

If Prometheus/Grafana need external access:

Nginx Proxy Manager:
- prometheus.azcomputerguru.com → http://172.16.3.30:9090
- grafana.azcomputerguru.com → http://172.16.3.30:3000

Enable SSL/TLS certificates
Add access restrictions (IP whitelist, authentication)

6. Configure Alerting

# Option A: Email alerts via Alertmanager
# Install and configure Alertmanager
# Update Prometheus to send alerts to Alertmanager

# Option B: Grafana alerts
# Configure notification channels in Grafana
# Add alert rules to dashboard panels

7. Test Backup Restore

# CAUTION: This will DROP and RECREATE the database
ssh guru@172.16.3.30
cd ~/guru-connect/server

# Test on a backup
./restore-postgres.sh /home/guru/backups/guruconnect/guruconnect-YYYY-MM-DD-HHMMSS.sql.gz

Monitoring Dashboard

Once Grafana dashboard is imported, you'll have:

Real-Time Metrics (10 Panels)

1. Active Sessions - Gauge showing current active sessions
2. Requests per Second - Time series graph
3. Error Rate - Graph with alert threshold at 10 errors/sec
4. Request Latency - p50/p95/p99 percentiles
5. Active Connections - By type (stacked area)
6. Database Query Duration - Query performance
7. Server Uptime - Single stat display
8. Total Sessions Created - Counter
9. Total Requests - Counter
10. Total Errors - Counter with color thresholds

Alert Rules (6 Alerts)

1. GuruConnectDown - Server unreachable >1 min
2. HighErrorRate - >10 errors/second for 5 min
3. TooManyActiveSessions - >100 active sessions for 5 min
4. HighRequestLatency - p95 >1s for 5 min
5. DatabaseOperationsFailure - DB errors >1/second for 5 min
6. ServerRestarted - Uptime <5 min (info alert)

Troubleshooting

Service Won't Start

# Check logs
sudo journalctl -u SERVICE_NAME -n 50

# Common services:
sudo journalctl -u guruconnect -n 50
sudo journalctl -u prometheus -n 50
sudo journalctl -u grafana-server -n 50

# Check for port conflicts
sudo netstat -tulpn | grep PORT_NUMBER

# Restart service
sudo systemctl restart SERVICE_NAME

Prometheus Not Scraping

# Check targets
curl http://localhost:9090/api/v1/targets

# Check Prometheus config
cat /etc/prometheus/prometheus.yml

# Verify GuruConnect metrics endpoint
curl http://172.16.3.30:3002/metrics

# Restart Prometheus
sudo systemctl restart prometheus

Grafana Can't Connect to Prometheus

# Test Prometheus from Grafana
curl http://localhost:9090/api/v1/query?query=up

# Check data source configuration
# Grafana > Configuration > Data Sources > Prometheus

# Verify Prometheus is running
sudo systemctl status prometheus

# Check Grafana logs
sudo journalctl -u grafana-server -n 50

Backup Failed

# Check backup logs
sudo journalctl -u guruconnect-backup -n 50

# Test manual backup
cd ~/guru-connect/server
./backup-postgres.sh

# Check disk space
df -h

# Verify PostgreSQL credentials
PGPASSWORD=gc_a7f82d1e4b9c3f60 psql -h localhost -U guruconnect -d guruconnect -c 'SELECT 1'
