System Administration Guide: Advanced Administration

ProcedureHow to Set Up Automatic Data Collection

  1. Become superuser or assume an equivalent role.

    Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

  2. Run the svcadm enable system/sar:default command.

    This version of the sadc command writes a special record that marks the time when the counters are reset to zero (boot time).

  3. Edit the /var/spool/cron/crontabs/sys crontab file.

    Note –

    Do not edit a crontab file directly. Instead, use the crontab -e command to make changes to an existing crontab file.

    # crontab -e sys
  4. Uncomment the following lines:

    0 * * * 0-6 /usr/lib/sa/sa1
    20,40 8-17 * * 1-5 /usr/lib/sa/sa1
    5 18 * * 1-5 /usr/lib/sa/sa2 -s 8:00 -e 18:01 -i 1200 -A

    For more information, see the crontab(1) man page.
