Candidates may include 'top' and 'htop' as tools for tracking system performance in real time. A dynamic view of the system, including CPU, memory, and load average utilization, is displayed by these instructions.
Using 'iostat' for I/O statistics and 'vmstat' for memory statistics provides an additional choice. Performance optimization may benefit greatly from the more thorough breakdown of system resource utilization that these tools offer.
Seek applicants who can describe the significance of tracking various metrics and how they would use this data to identify and address performance problems.
