Dell PowerVault ME5 Series Administrator's Guide

Retrieve historical disk-performance statistics

Perform the following steps to retrieve historical disk-performance statistics:

1. In the PowerVault Manager, prepare to use FTP/SFTP:
   1. Determine the network-port IP addresses of the system controllers. See Configuring controller network ports.
   2. Verify that the FTP/SFTP service is enabled on the system. See Enabling or disabling system-management settings.
   3. Verify that the user you will log in as has permission to use the FTP interface. See User settings.
2. Open a Command Prompt (Windows) or a terminal window (UNIX) and go to the destination directory for the log file.
3. Type:
   sftp -P <port> <controller-network-address> or

   ftp <controller-network-address>

   For example:

   sftp -P 1022 10.235.216.152 or

   ftp 10.1.0.9

4. Make sure the client is in binary transfer mode. Enter:
   binary
5. Log in as a user that has permission to use the FTP/SFTP interface.
6. Enter:
   get perf:<date/time-range> <filename.csv> where:

   • date/time-range is optional and specifies the time range of data to transfer, in the format: start.yyyy-mm-dd.hh:mm.[AM|PM].end.yyyy-mm-dd.hh:mm.[AM|PM]. The string must contain no spaces.
   • filename.csv is the file that contains the data. Dell recommends using a filename that identifies the system, controller, and date.
   get perf:start.2019-01-26.12:00.PM.end.2019-01-26.23:00.PM Storage2_A_20120126.csv

   In FTP, wait for the message Operation Complete to appear. No messages are displayed in SFTP; instead, the get command returns once the download is finished.

7. Quit the FTP/SFTP session.
