Monitoring CPU utilization in Unix is a critical task for system administrators and performance analysts. It provides valuable insights into the overall health and performance of the system, helping identify potential bottlenecks and optimize resource allocation.
High CPU utilization can lead to performance degradation, slow response times, and even system crashes. Regularly checking CPU utilization allows you to proactively address issues, prevent outages, and ensure optimal system operation.
Bandwidth utilization refers to the amount of data transferred over a network connection within a given period. Monitoring bandwidth utilization is crucial for network administrators to ensure efficient network performance and identify potential bottlenecks or security breaches.
Understanding bandwidth utilization helps in planning network capacity, optimizing resource allocation, and preventing network congestion. It also aids in troubleshooting network issues, detecting unauthorized access, and ensuring compliance with service level agreements (SLAs). Historically, bandwidth utilization was measured using specialized tools or by analyzing network traffic logs.
