Tell Me What Does Sar Provides And At Which Location Sar Logs Are Stored?

⟩ Tell me what does Sar provides and at which location Sar logs are stored?

Sar Collect, report, or save system activity information. The default version of the sar command (CPU utilization report) might be one of the first facilities the user runs to begin system activity investigation, because it monitors major system resources. If CPU utilization is near 100 percent (user + nice + system), the workload sampled is CPU-bound.
