Monitoring Resources

(OBJ .)

Monitoring Systems

• Involves observing a computer system's performance, including
  • CPU
  • Memory
  • Disk usage
  • Network performance

Baseline

• A reference point representing normal system behavior under typical operating conditions
• Baseline metrics can include CPU usage, memory utilization, disk activity, and network traffic
• Deviations from the baseline can indicate potential issues, prompting proactive troubleshooting and maintenance
• Check Secure Baselines

Application Monitoring

• Focuses on managing and monitoring software application performance and availability
• Tracks errors, bottlenecks, and issues that may affect an application's performance or user experience
• Tools like New Relic and AppDynamics track response times and error rates
• Slower response times may indicate code problems or resource deficiencies

Infrastructure Monitoring

• Observes physical and virtual infrastructure, including servers, networks, virtual machines, containers, and cloud services
• Provides insights into network traffic, bandwidth usage, and device status
• Tools like SolarWinds and PRTG Network Monitor help monitor network infrastructure
• Overloaded network switches can signal the need for additional capacity or configuration issues
