Veritas Access Troubleshooting Guide

To use the iostat command

• To use the Support> iostat cpu command, enter the following:

  Support> iostat cpu [nodename] [interval] [count]

  nodename	The name of the node from where the report is generated. The default is console for the Management Console.
  interval	The duration between each report in seconds. The default is 2 seconds.
  count	The number of reports generated at the interval entered in seconds. The default is one report.

  where the nodename option asks for the name of the node from where the report is generated. The default is console for the Veritas Access Operations Manager console.

  For example, to generate the CPU utilization report of the console node, enter the following:

  Support> iostat cpu access_01
  Linux 2.6.16.60-0.21-smp (access_01)       02/09/16
  
  avg-cpu:  %user   %nice  %system  %iowait  %steal   %idle
             1.86    0.07     4.53     0.13    0.00   93.40

To use the iostat device command

• To use the Support> iostat device command, enter the following:

  Support> iostat device [nodename] [dataunit]
  [interval] [count]

  nodename	The nodename option asks for the name of the node from where the report is generated. The default is console for the Management Console.
  dataunit	The dataunit option lets you generate the report in block(s) or kilobytes(s). The default is block(s).
  interval	The duration between each report in seconds. The default is two seconds.
  count	The number of reports generated at the interval entered in seconds. The default is one report.

  For example, to generate a device utilization report of a node, enter the following:

  Support> iostat device access_01 Blk
  Linux 2.6.16.60-0.21-smp (access_01)       02/09/16
  
  Device:      tps   Blk_read/s   Blk_wrtn/s   Blk_read   Blk_wrtn
