Note       This feature returns extensive statistics about RecoverPoint system performance, by group, RPA (“box”), and site. The quantity and type of statistics depends on the filters specified in the CLI detect_bottlenecks command.

The standard output includes the following set of statistics:

  • WAN throughput
  • Total incoming data rate
  • Initialization (synchronization) output rate
  • CPU utilization
  • Compression ratio
  • Percentage of time in transfer (group only)
  • Percentage of time in initialization (group only
