Description

Starts the collection of the read and write statistics with the I/O size and the logical block addressing (LBA) information on

the metro node virtual volumes through periodic polling. This command starts generating the performance data, which helps

resolve I/O performance issues with metro node. The statistics are available in the fe_perf_stats_<timestamp>.log file

at /var/log/VPlex/cli/.

Run this command on each cluster to collect the front-end performance statistics. After you run this command,

the system continues to collect the front-end performance statistics until you run the front-end-performance-stats

stop command.
