The SnapMirror audit log provides a running log of SnapMirror relationships. It shows starting, restarting, and ending information for each SnapMirror relationship. This script reads in the log file(s) and parses the information into a usable CSV or XLSX file. The output produces the following details:

Source (the source of the SnapMirror relationship)
Destination (the destination of the SnapMirror relationship
Type (request, start, or end)
KB Transferred (produced only for end type entries)
Time Stamp (the time stamp associated with the log file entry)
Duration (recorded in seconds)
Throughput (in KB/s of data and Kb/s of actual network throughput taking in account compression)
Network Compression Ratio
Concurrency (number of total SnapMirrors transferring during any part of the time this SnapMirror was transferring)
Detail of SnapMirror
