On the San Health Report, SAN Ports tab, what does the "Change" column indicate? Particularly with regard to Frames Transmitted and Frames Received.
SAN Health takes 2 snapshots of the port error counters and the port stats counters. One at the start of the audit and one at the end. The duration between these is set by how long the user chooses to capture throughput data from the switches for. If they say capture 24 hours worth of port throughput data then the port error and port stat counters will be captured either side of that 24 hour period. The change field next to each counter value represents the delta between the two captures and provides a really good insight into potential problems. The time delta between the captures is listed in the heading of that section of the report.
Thank you for your quick reply. Just to clarify, with regard to the transmitted frames and received frames, the change column indicates how many frames were transmitted (or received) in that sample? The reason I ask is for some of the ports in my sample, that number seems too small.
