SAN Performance Monitoring

With SAN statistics taken at preset intervals that are sampled or averaged, detailed performance information is lost as a large amount of traffic passes through between the intervals. Statistics are also aggregated, such as Total MB/sec capacity on a particular port, which means they cannot provide visibility into the individual application transactions that make up the traffic on that port.

With continuous line rate monitoring, performance statistics and calculations are gathered by hardware, which provides the most complete performance information. This offers thorough statistical analysis on complete application transaction times, absolute maximum/average/minimum response times, all CRC errors that occurred, logins/logouts, aborts, etc. The comprehensive performance statistics accessible with NetWisdom's hardware-based probe approach offers an opportunity to accurately measure complete application transaction times within the SAN to improve enforcement of service level agreements. Visibility into this in-depth performance data provides the ability to fully analyze and proactively tune your SAN for optimal performance.
