---

## Next Steps (Required)

### 1. Change Grafana Password
```bash
# Access Grafana
open http://172.16.3.30:3000

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

### 2. Import Grafana Dashboard

```bash
# 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

```bash
# 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

```bash
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

```bash
# 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

```bash
# 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

```bash
# 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

```bash
# 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

```bash
# 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

```bash
# 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'
```
