How often do Perpetual Monitors record stats in VPLEX?

Perpetual Monitors in VPLEX are designed to gather and record statistics at regular intervals to provide near real-time visibility into system performance and health. The correct interval at which these monitors record stats is every 30 seconds. This frequency allows for a balance between obtaining timely data and minimizing the system resources consumed by the constant monitoring process.

Recording stats every 30 seconds enables VPLEX administrators to have a granular view of system performance metrics without overwhelming the system with excessive logging. This interval is particularly useful for detecting trends and anomalies, thereby allowing for proactive management of the storage environment.

Having a more frequent interval, such as every minute or every 15 seconds, could lead to high overhead and potentially impact system performance due to the resource usage required to process and log the collected data. Conversely, a longer interval such as every hour would not provide timely enough insights for effective monitoring and management of system health. Hence, the choice of 30 seconds strikes an ideal balance.
