In performance monitoring, which log type captures statistics across performance counters over time?

• A. Counter logs
• B. Event logs
• C. Security logs
• D. System logs

Answer: (A)

Capturing statistics across performance counters over time requires a log that records each counter’s value at regular intervals, producing a time-series dataset. That is what counter logs provide. They collect data from multiple performance counters, timestamped, so you can observe trends, compare counters, and establish baselines. This is different from event logs, which store discrete events with messages, security logs for audit-related events, or system logs for general operating-system events. In performance monitoring tools, you set up counter logs to continuously log counter values, enabling analysis of how resource usage changes over time. So, the log type that captures statistics across performance counters over time is counter logs.
