The components of IT infrastructure that should be monitored include:
1. Servers
2. Network devices (routers, switches, firewalls)
3. Storage systems
4. Applications and services
5. Databases
6. Virtual machines and containers
7. Cloud resources
8. End-user devices (desktops, laptops, mobile devices)
9. Power and cooling systems
10. Security systems and logs
Log monitoring plays a crucial role in infrastructure monitoring by providing insights into system performance, identifying errors, detecting security threats, and ensuring compliance. It helps in troubleshooting issues by analyzing log data from various sources, allowing for proactive maintenance and quick response to incidents.
SNMP, or Simple Network Management Protocol, is a protocol used for managing and monitoring network devices. It allows network administrators to collect and organize information about devices such as routers, switches, and servers, and to manage their performance and configuration. SNMP operates by using a manager to request data from agents on the devices, which respond with the requested information, enabling effective network monitoring and management.
Key metrics to monitor on a server include:
1. CPU Usage
2. Memory Usage
3. Disk I/O
4. Network Traffic
5. Disk Space Utilization
6. System Load Average
7. Process Count
8. Error Rates
9. Temperature and Power Usage
10. Application Performance Metrics
To monitor cloud infrastructure in AWS, Azure, or GCP, you can use the following tools:
– **AWS**: Amazon CloudWatch for metrics and logs, AWS CloudTrail for API activity, and AWS Config for resource configuration tracking.
– **Azure**: Azure Monitor for performance and health metrics, Azure Log Analytics for log data, and Azure Security Center for security monitoring.
– **GCP**: Google Cloud Monitoring for resource metrics, Google Cloud Logging for log management, and Google Cloud Operations Suite for overall monitoring and management.
Additionally, third-party tools like Datadog, New Relic, or Prometheus can also be integrated for comprehensive monitoring across multiple cloud platforms.
