Working with System Statistics (SYSSTAT)

The System Statistics (SYSSTAT) is a tool to monitor system resources and their performance on LINUX/UNIX systems. It contains utilities that collect system information, report CPU statistics, report input-output statistics, and so on. The SYSSTAT tool provides an extensive and detailed data for all the activities in your system.

The SYSSTAT contains the following utilities for analyzing your system:

  • sar
  • iostat
  • mpstat
  • pidstat
  • nfsiostat
  • cisfsiostat

These utilities collect, report, and save system activity information. Using the reports generated, you can check the performance of your system.

The SYSSTAT tool is available when you install the appliance.

On the Web UI, navigate to System > Task Scheduler to view the SYSSTAT tasks. You must run the following tasks to collect the system information:

  • Sysstat Activity Report to collect information at short intervals
  • Sysstat Activity Summary to collect information at a specific time daily

The following figure displays the SYSSTAT tasks on the Web UI.

SYSSTAT Task Scheduler

The logs are stored in the /var/logs/sysstat directory.

The tasks are disabled by default. You must enable the tasks from the Task Scheduler for collecting the system information.
