ALTER USER hyperic PASSWORD 'your_password';
GRANT ALL PRIVILEGES ON DATABASE hypericdb TO hyperic;

Step 3: Install Hyperic Server

# Run the installer
./setup.sh

# Follow the interactive prompts:
# - Accept license agreement
# - Choose installation directory
# - Configure database connection
# - Set admin credentials

Example configuration during installation:

Installation Directory: /opt/hyperic
Database Type: PostgreSQL
Database URL: jdbc:postgresql://localhost:5432/hypericdb
Database Username: hyperic
Database Password: your_password
Admin Username: hqadmin
Admin Password: hqadmin123

Configuring Hyperic Agent

The Hyperic Agent collects metrics from monitored systems and sends them to the HQ Server.

Agent Installation

# Download and extract agent
wget https://support.hyperic.com/download/hyperic-hq-agent-5.8.4-linux.tar.gz
tar -xzf hyperic-hq-agent-5.8.4-linux.tar.gz
cd hyperic-hq-agent-5.8.4

# Run agent setup
./setup.sh

Agent Configuration

Configure the agent to connect to your HQ Server:

# Edit agent properties
vim conf/agent.properties

# Key configuration parameters:
agent.setup.camIP=192.168.1.100
agent.setup.camPort=7080
agent.setup.camSSL=false
agent.setup.camLoginUsername=hqadmin
agent.setup.camLoginPassword=hqadmin123

Starting the Agent

# Start the agent
./hq-agent.sh start

# Verify agent status
./hq-agent.sh status

# Example output:
HQ Agent (pid 12345) is running...

System Resource Monitoring

Hyperic provides comprehensive system monitoring capabilities for Linux environments.

  get metric "CPU Usage" for platform "linux-server-01"

# Example output:
Timestamp: 2025-08-26 07:30:00
CPU Usage: 45.2%
CPU Idle: 54.8%
CPU System: 12.3%
CPU User: 32.9%

Memory Monitoring

Track memory usage and available resources:

# Memory metrics command
hq-cli.sh get metric "Memory Usage" for platform "linux-server-01"

# Sample output:
Total Memory: 8192 MB
Used Memory: 4096 MB (50%)
Free Memory: 4096 MB (50%)
Cached Memory: 1024 MB
Buffer Memory: 512 MB

Disk Space Monitoring

Monitor disk usage across mounted filesystems:

# Disk utilization metrics
hq-cli.sh get metric "Disk Usage" for platform "linux-server-01"

# Example output:
/dev/sda1 (/): 75% used (45GB/60GB)
/dev/sda2 (/home): 60% used (120GB/200GB)
/dev/sda3 (/var): 85% used (170GB/200GB)

Application Performance Monitoring

Web Server Monitoring

Monitor Apache HTTP Server performance:

# Auto-discover Apache services
hq-cli.sh autodiscover platform "linux-server-01"

# View Apache metrics
hq-cli.sh get metric "Requests per Second" for service "Apache 2.4"

# Sample output:
Current Requests/sec: 125.5
Total Requests: 1,250,000
Active Connections: 45
Idle Workers: 105

  --name "High CPU Usage" \
  --description "Alert when CPU usage exceeds 80%" \
  --metric "CPU Usage" \
  --condition ">" \
  --threshold 80 \
  --resource-type "Platform"

[email protected]
hyperic.smtp.password=smtp_password
[email protected]

Performance Optimization Techniques

Agent Optimization

Optimize agent performance for large-scale deployments:

# Edit agent properties for optimization
vim conf/agent.properties

# Performance tuning parameters:
agent.maxBatchSize=500
agent.batchInterval=60000
agent.queueSize=10000
agent.compression=true

Server Optimization

Optimize HQ Server for better performance:

# JVM tuning in startup script
vim bin/hq-server.sh

# Add JVM options:
export JAVA_OPTS="-Xms2g -Xmx4g -XX:NewRatio=2 \
  -XX:+UseG1GC -XX:MaxGCPauseMillis=200"

Troubleshooting Common Issues

Agent Connection Problems

Diagnose agent connectivity issues:

# Check agent logs
tail -f logs/agent.log

# Test connectivity
telnet hyperic-server 7080

# Verify agent configuration
grep -E "camIP|camPort" conf/agent.properties

Performance Issues

Identify and resolve performance bottlenecks:

# Check server logs for errors
tail -f logs/hq-server.log | grep ERROR

# Monitor database connections
psql -h localhost -U hyperic -d hypericdb -c \
  "SELECT count(*) FROM pg_stat_activity;"

# Review system resources
top -p $(pgrep -f hyperic)

Best Practices for Hyperic Deployment

Security Considerations

• Use SSL/TLS encryption for agent-server communication
• Implement strong authentication credentials
• Regularly update Hyperic components
• Restrict network access to monitoring ports

Scalability Planning

• Distribute agents across multiple servers
• Implement database clustering for high availability
• Use load balancers for HQ Server instances
• Plan for data retention and archival

Maintenance Procedures

# Regular maintenance script
#!/bin/bash
# Hyperic maintenance script

# Backup database
pg_dump -U hyperic hypericdb > hyperic_backup_$(date +%Y%m%d).sql

# Clean old log files
find /opt/hyperic/logs -name "*.log.*" -mtime +30 -delete

# Restart services if needed
./hq-server.sh restart
./hq-agent.sh restart

Advanced Monitoring Scenarios

Custom Metric Collection

Create custom metrics for specialized monitoring:

# Custom script for application metrics
#!/bin/bash
# custom_app_metrics.sh

APP_RESPONSE_TIME=$(curl -w "%{time_total}" -s -o /dev/null http://localhost:8080/health)
echo "app.response.time:${APP_RESPONSE_TIME}:gauge"

QUEUE_SIZE=$(rabbitmqctl list_queues | awk '{sum+=$2} END {print sum}')
echo "app.queue.size:${QUEUE_SIZE}:gauge"

Integration with External Tools

Integrate Hyperic with popular DevOps tools:

# Grafana integration via API
curl -X POST "http://hyperic-server:7080/hq/api/measurement" \
  -H "Authorization: Bearer $API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"metric": "cpu.usage", "value": 75.2, "timestamp": 1724646600}'
