Fix        You will need to log the output with PuTTY or a similar application.

  1. Log into the floating IP as admin (password: admin).
  2. Run the command detect_bottlenecks and answer the prompts as followsLocal-171> detect_bottlenecks

    Enter mode (select one from the list), or press Enter to default mode (default is System overview and bottleneck analysis)

    1) System overview and bottleneck analysis
    2) Detection of initialization periods
    3) Detection of high load periods
    4) General detection including initialization and high load periods with peak writing analysis

    Select, or press ‘ENTER’: 4

    Enter earliest time, or press ‘ENTER’ for the earliest time available
    (Format: HH:MM [DD/MM/YYYY]  OR  wks/days/hrs/mins ago)

    Enter latest time, or press ‘ENTER’ for the latest time available
    (Format: HH:MM [DD/MM/YYYY]  OR  wks/days/hrs/mins ago)

    Do you want advanced overview? (default is no)

    1) yes
    2) no

    Select, or press ‘ENTER’: 1

    Type of overview? (default is normal)

    1) normal
    2) detailed

    Select, or press ‘ENTER’: 2

    Enter peak_duration(secs/mins/hrs),e.g I/O peaks (default is 5 minutes)

    Enter group name(s), separated by ‘,’ if more than one  (default is all groups)

    Warning: This operation may take a long time. Do you want to continue(y/n)?y

  3. Forward output of command to EMC RecoverPoint Technical support for analysis.
  4. After running the bottleneck command in CLI, download the output file ” bottlenecks.csv ” using a web browser:
    http://<rpa_ip_address>/info – user webdownload, password webdownload

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
