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/.

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

stop command.
