Can you describe the tools and methods you use for system state and performance analysis?

To analyze the state and performance of the system, I use the following tools and methods:

• Resource monitoring: top, htop, vmstat, iostat for tracking CPU, memory, disk, and network load.
• Logging: viewing logs of system services (journalctl, syslog) to identify errors and anomalies.
• Profiling: tools like perf, strace for performance analysis and bottleneck identification.
• Monitoring systems: Prometheus, Grafana for collecting metrics and real-time visualization.
• Load analysis: load testing with Apache JMeter or similar.

These methods help identify problems and optimize system operation.
